Title: Re: Thoughts on after market muffler Post by justin_o_guy2 on 05/09/20 at 17:24:28 The easiest to tune the bike to, most affordable, with an easy tone, is a Harley muffler..The Dyna muffler, the right model, fits pretty easily. REquires a piece added, with a few degrees of turn out,, |

Title: Re: Thoughts on after market muffler Post by batman on 05/09/20 at 17:56:32 If loud pipes save lives ? No ,common sense saves lives. I don't think Voodoo makes a good muffler ,they sell a fiberglass baffle, if I'm not mistaken ,and fiberglass cooks and blows out the tailpipe in short order leaving you to retune your carb because it's now a straight pipe. Loud makes you deaf, gives bad performance and bad mileage. I run an unmolested H-D with great results. |

Title: Re: Thoughts on after market muffler Post by SoC on 05/09/20 at 18:04:44 Jason, I have one of these on my '03'. Have been riding with it since Oct. This muffler is sold under a couple different names, but VooDoo is the big purveyor of it. First thing I will tell you is, it is not a straight up fit. The whole thing does not align very well and if you look at pictures and videos a lot of folks don't attach it to anything beyond the header. That is not a good idea. You can finagle everything to get it to bolt to mounting bracket but it is not positioned very well. I will start by saying that the fast, quick fit up position, the turn out is basically perpendicular to the bike, hence a turn out. There are 2 things. One it doesn't look all that great and second it has some position issues. I am the first guy to promote the concept of "Ride Safe, Ride Loud", and the thing is loud. But, if just installed as out of the box, it has a couple issues. First it makes the bike sound kind of like an obnoxious lawn mower. Second, that sound is emphasised because it is being broadcast out at 90 degrees. So you are in effect projeting it out from the side of the bike. How to address the sound and fit issues gets a little complicated. First it works better if you convert the mounting to a 3/4 turn down. Now you are not projecting the sound out to the side but rather down towards the road. Second you need to add a baffle or 2 to deepen and make the sound a little richer. When you install it and hear it on your bike it does not sound like it does in the you tube videos, phone camera's do not really capture good sound for things like this. So now you are at the situation where the thing does not just fit up with a bolt holding it onto the bracket, or maybe nothing more then mounted to the header. So what do you do to make it a safe and complete install. Well you need to get a connector between the header and it and you need to fabricate a mounting bracket/plate to attach it to the bracket on the bike. I did it by buying some exhaust pipe and having a muffler shop bend and expand it on the header end and I fabricated a stainless mounting plate to attach it to the bracket on the bike. To get the sound right I installed small baffles in it, one at the end of the connector to the header and another in the rear of the muffler. With the sound right now I have still not figured the carb adjustments necessary to control the back fire it has created due to increased flow and reduced back pressure. The second catalytic baffle at end helped. They are inexpensive so give it a try and if you are happy with sound, just bolt it up and ride. Mufflers really do need some shock mounting though and there is really not a way to effectively do that out of the box with what is provided. I will add the chrome one I installed began to blue imediately. Some could be attributed to the placement of a diversion baffle right in the front end of it. I do have all the parts needed to do a mount like mine, I fabricated extras as I was doing it, as I have not only an '03' but a 2011 also. I will post pictures of the parts fabbed. So now you have it on |

Riding at times of day with good lighting saves lives. Not riding over your head saves lives. Good maintenance saves lives. Loud pipes make you appear to be some type of a-hole biker. |

Title: Re: Thoughts on after market muffler Post by eau de sauvage on 05/09/20 at 19:22:25 If the Dyna muffler is not loud enough for someone then that person is a pest. Relying on other people to see/hear you is not going to save your life. Instead of a SMIDSY, you'll get hit by a SMIDHY. FFIW I have a modulator on my headlight it's a passive safety feature not used often enough IMHO Having said that, the Dyna is $700 a pair new but able to be found for under $50 in as new condition, ie never used. What's nice about it is that when cruising it's not obnoxiously loud but if you give it some wellie, it definitely pieces through the din. |

Title: Re: Thoughts on after market muffler Post by srinath on 05/10/20 at 09:47:21 There are clearly 2 cases where nothing but a loud pipe saved case 1. Someone from me, and case 2 me from someone. Case 1. 20012-13. I am about to turn left in my car, its near about dark, when I look left and see a jeep with high beams on far far away. But I am hearing a loud twin cyl sound. I look to my right. Nothing. Look back left and the far away Jeep was a Harley with twin headlights and really close. And no high beams. He was just close. No loud pipe he'd be down and likely pretty badly hurt. Case 2. 2018. I am riding down a frontage road. There's a temporary road sign that's 3' high and 3X the size of a normal sign, but I see a car at the stop sign waiting to turn left, but I am going too fast to stop. The car is a bit tentative in turning - likely he heard me, but the highway to my left was likely making him less able to pinpoint it. He moves 1/2 way in and slams the brakes and I see a look that says oh that was what the sound was. Ever since I hate those temporary stupid short and huge road signs. Nothing but sound saved me and someone from me. Cool. Srinath. |

Title: Re: Thoughts on after market muffler Post by justin_o_guy2 on 05/10/20 at 16:06:59 I know one thing for sure.. I can holler louder than the horn on the savage.. After the horn had no effect, I screamed at some broad in a pasrking lot and she woke up. |

Title: Re: Thoughts on after market muffler Post by batman on 05/10/20 at 17:39:13 Jasongibby, You're correct I'm not a nice guy ,however I am an honest guy ,everything I said was straight forward and correct. I've been riding over 40yrs and aSavage for 25, and I'll be 72 next month. does that qualify me as old school or do I have to run an obnoxiously loud muffler to past your test? |

Title: Re: Thoughts on after market muffler Post by Gary_in_NJ on 05/10/20 at 18:03:17 Then why bother with a muffler at all? You need to make all the noise. Be heard man. Save a life. |

Title: Re: Thoughts on after market muffler Post by ohiomoto on 05/11/20 at 20:36:21 RANT ALERT!!!!! Loud pipes are obnoxious and there is no actual proof that they save lives. Plenty of riders with loud pipes die every year. That myth is mostly purveyed by self-centered douchbags who are in fact breaking the law in most cases. I prefer to be semi-considerate to my fellow human beings and try to keep my noise within reason. People have the right to reasonable peace and quiet. That's why we have laws regarding noise. Helmets have been proven to save lives. But, far too many loud pipe douchbags refuse to wear them. It's their right they say. Go figure?? Choosing a loud pipe affects society as a whole and it's not actually your right to make noise. Don't get me wrong, I'm not against rights. I choose an open face helmet and don't wear any other real protective clothing. It's my right to choose in Ohio. Sure, I'll be in a world or hurt if I get in an accident. I just hope my helmet might save my life. But those are choices that mostly affect my life along with my family. I do not have the right to make as much noise as I want. And ANYONE who throws a leg over a bike is an ACTUAL rider. Grow up. Loud pipe or not, I sincerely hope you are safe out there. |

Title: Re: Thoughts on after market muffler Post by badwolf on 05/11/20 at 21:18:56 Just when the ''oil wars'' cool down a little, we get a new ''LOUD PIPES WAR''. I often ride 10 - 12+ hour days, so loud pipes are out of the question. The test of your pipes being too loud is- 1- Do your neighbors throw rotten fruit or vegies at you? ( or do they want to ) 2- Can you still hear anything over that ringing in your ears? I won't ride near bikes with really loud pipes, but that is not a issue for long as most of them think 10 miles is a LONG trip. BUT, I will admit if you are not paying attention to EVERYTHING & EVERYONE around you at ALL times,( like you should IF you want to make it home without bleeding ) loud pipes annoying everyone around you MIGHT help them know you are there. And it might give them a reason to do something bad. Just ride like everyone else on the road is sooner or later going to try to kill you! |

Title: Re: Thoughts on after market muffler Post by Psydton3 on 05/13/20 at 04:00:00 I run a dyna muffler on my 2016 S40. It has a built in catalytic and to be honest once warmed up it's quite loud at highway speeds but quite tame through traffic. Just what I wanted and very cheap. I scored a pair of dyna mufflers for $40 aud. Great value imho. ;) |

Title: Re: Thoughts on after market muffler Post by SoC on 05/13/20 at 12:21:40 Hey, sorry to have started a fire storm here. Just trying to pass some advice to someone considering a VooDoo exhuast. For the record, there is a difference between louder and loud. Many have made the Dyna swap, why, often for some, a more dignified sound. But it is louder then the stock muffler. I stated right up front that the VooDoo is loud and obnoxious. That is why I have put not 1, but 2 additional baffles in mine. As it is now it is louder then a Dyna, but not exceptionally. I actually built and installed the first baffle so as it is not a stright shot. It is now set up so there is an offset in direction of all the various inward bent diversion baffles in the set-up, you can not see any light through the thing. At the back end I added a second catalytic baffle to quite it more. I have spent most of my life in the sound industry. I have worked as a live mix engineer and speaker cabinet designer and builder and custom fabricator to the sound and stage lighting industry. One thing I will bring up, and I did mention this in my post was the issue of directionality of sound. As a quick explanation, sound is actually the propagation of a wave and waves move in direction based on the source of the energy that created it. In the case of a muffler that would be the exit of the tailpipe. On most tailpipes that is straight out the back, so the wave is projected out away from where you actually sit on the bike and hear it. The point being your pipe may be loud you just don't get the full effect of it unless you are behind the bike. The thing with a turn out (like the VooDoo) is just that, the source of the wave is pointed outward towards the side, hence why I recommended it also must be modified to be a partial turn down. Proprogation as a turn down is not out into the open air but more down towards the pavement. Often exhausts (turn outs or straight fire back are perceived as excessively loud because they are broadcasting the waves directly outward. So what I am saying is the direction of the exit of the exhaust can also influence the perception how loud it is. My VooDoo with the mods is not too loud when at idle, or low rpm cruising, but it does annonce you when you accelerate in passing through the blind spot in a cars rear view mirror. I agree with the concept that nothing replaces responsible attentive riding practices. But noise is a factor that does get people to realize there may be a motocycle in their peripheral. In the era we all ride in today cars have become more vacuumed sealed, climate controlled, internet connected isolation boxes. It's not like the old days where people drove around with their windows down and exposed to their surroundings. With the windows up, A/C on and stereo blasting in my Lexus, the outside world could conceivably not exist. As a rider, I have trained myself for when I drive to exercise extra caution constantly looking for and listening for motorcycles and driving in accordance with how I would hope all drivers would do around me when on my bikes. What I see though are far too many riders who do not do the same when on their bikes. The reality is there are a lot of bad riders out there so if they feel a loud bike helps protect them, maybe it does, or maybe it makes them less cautious, can't answer for that. But if it does keep them from becoming a victim of some inattentive driver reading a text while driving or fiddling with the info system in their car, I guess that could be considered a good thing. As I think we have all been there I will quote Srinath on this "Nothing but sound saved me and someone from me". As a preference I don't necessarily promote the concept of "Loud Pipes, Save Lives", I prefer "Ride Loud, Ride Safe". |

Title: Re: Thoughts on after market muffler Post by badwolf on 05/13/20 at 13:52:12 Hopefully we have come to a cease fire in the ''LOUD PIPES WAR, without bloodshed! Everyone rides a little differently, and has different likes & dislikes. (that is why they make more than one motorcycle ) |

Title: Re: Thoughts on after market muffler Post by philthymike on 05/14/20 at 15:36:04 In my observations of riders in my local area I've noticed that those with the loudest pipes ride the least. So for them the loud pipe may benefit their lifespan because they spend less time actually riding and negotiating traffic. It's not that the loudness is unbearable to them because they all wear hearing protection. It's that they're only out there for purely narcissistic reasons. Look at me, rev, look at me, rev, look at me rev, rev. After a few laps of the neighborhood they park at a bar and sit on their bikes outside until they've formed a little sewing circle. IMHO it's the same exact mentality as a 5 year old with a box of snaps throwing them at everyone in throwing distance to get attention. In fact I think all the Harley guys in my neighborhood rev, rev, revving away obnoxiously at the traffic light on my corner would probably be just as happy with a box of snaps as the average 5 y/o. Snaps cost much less than motorcycles and insurance too. For a mere fraction of the cost of motorcycle ownership they could invest in a lifetime supply of snaps and happily obnoxiously seek the attention of grownups until they are in a wheelchair outside of a nursing home participating in actual sewing circle :D |

Each day I rode my Ducati to work I would really open her up on that street because it's long and straight with no intersections and nothing but offices. And when I crank up the Duck she lets an unholy roaring howl usually only heard on the highway. One thing I never paid much attention to was those 3 little houses on that street just before the office parks. Turns out one of those houses belongs to a local cop. Oops. Yeah, he started waiting for me each day and trying to speedtrap my tushy. My reflexes and situational awareness frustrated him so he just started following me home. Finally one day he made it clear he didn't appreciate my howling passed his house every evening. If he was a prick he could have given me a real hard time. I do the speed limit on that street now. Sometimes you just attract the wrong kind of attention. I should point out that my Duck has the stock muffler. But there's a servo valve built into the exhaust. At low RPM it restricts the sound pressure so the bike will pass noise regulations. When you hit it the valve opens all the way and sound pressure goes way up. |

Title: Re: Thoughts on after market muffler Post by Gary_in_NJ on 05/15/20 at 06:44:53 The OP, Jasongibby94, has not been back since declaring that we aren't "actual" riders since some us don't like to make a lot of noise. I can clearly see how making a lot of noise is the very essence of motorcycling, just as smoking is the very essence of breathing. It all goes together, don't you see. |

Title: Re: Thoughts on after market muffler Post by batman on 05/17/20 at 17:09:15 It seems odd that someone would take as fact that loud pipes save lives ,when research shows that 77% of motorcycle accidents are from frontal crashes and only 3% from bikes that are struck in the rear. I think that until exhaust pipes start facing forward , I'll be more inclined to rely on defensive driving. Driving like you're invisible ( assuming a car pulling out doesn't see you) will allow you a longer life than hoping he hears your loud pipe. Who hasn't had a car pull out in front of them? |
