Title: Ain't whistling dixie no more..... Post by T-Mack1 on 09/21/07 at 14:29:09 It ain't whistling dixie no more..... Or....it doesn't sound like a old VW bug any more either. I was told it sounded like a ATV (ouch!!) and another "friend" said it sounded like his Dad's old Beetle (I admit that it did sound like that whistle the old VW's had just over idle and at a easy cruise speed. ) http://www.users.fast.net/~tommack/Dyna-Muffler.jpg Had a day off (had to burn up vacation or lose it) so mounted the Dyna muffler I got on Ebay. It's a little louder than I wanted but it does sound better. It "sort of" bolted up. I didn't get any mounting hardware with the muffler so I had to make a threaded piece to slide into the Dyna muffler mounting bracket to act as a nut. I used a piece of flat stock steel 1/4 "(zinc plated) and drilled a hole and ran a tap thru to fit the bolt I had. The stock doughtnut exhaust gasket was too thick so temporarliy used aluminum foil that I folded over several times and then wrapped around the header pipe (not sure where I'm going to look for gasket material). I reused the factory heat shield so I had to make a bracket to hold the back of the shield (normally mounts to factory muffler). Here's some pict's of the mounting . http://www.users.fast.net/~tommack/Dyna-Muffler.jpg see bigger pict at: http://www.users.fast.net/~tommack/Dyna-Muffler.jpg Mounted......it fit Yea!!! http://www.users.fast.net/~tommack/Muff-n-pipe.JPG see bigger pict at: http://www.users.fast.net/~tommack/Muff-n-pipe.JPG The mount bolted to the front stock bracket hole http://www.users.fast.net/~tommack/mount.JPG see bigger pict at: http://www.users.fast.net/~tommack/mount.JPG The heat shield bracket http://www.users.fast.net/~tommack/Shield-bracket.JPG see bigger pict at: http://www.users.fast.net/~tommack/Shield-bracket.JPG Took it for a drive.....yes bug on the teeth type ride Performance ? ? ? Stock'01 pilot jet, and a 150 main (thanks Lancer) with white spacer mod using washers (three metric washers from an old computer (hey, it's a good use for for the old clunker's)). Adjusted the pilot screw after warmed up, also had to adjust the idle a bit. Well,... when rev'ing the bike it does give some black puff's....but it didn't get black when running. Actually is a nice gray color. I think the puff while rev'ing is the fact that the slide is not perfect and doesn't get down fast enough on a quick rev. Back fire? ? ?......only if I get on it then let off otherwise it does not back fire on deceleration. It is much more throatier on deceleration. acceleration: Hard to say....but I do notice that it seems better when I lug it (2K rpm's on the tach). Before it sounded like it was almost pinging or knocking.... Other than it's a bit louder than I wanted, I am happy I did it. |

...please, don't say "Harley type". It is much easier on my sensibilities if you just use the terms "aftermarket" or "custom". The other phrase is just way too "wannabe", if ya know what I mean :P |

Title: Re: Ain't whistling dixie no more..... Post by Savage_Greg on 09/22/07 at 07:10:17 Oh, if it's any consolation, when a stock exhaust sounds like a whistling VW, that's a good thing. Why? Because when a VW engine whistles, that means it is actually tuned properly ;D |

Title: Re: Ain't whistling dixie no more..... Post by Hell, Billy on 09/22/07 at 19:30:12 Tell you what, I rejetted mine, did the spacer thing, monkeyed around with the belt tension, and took off about 15lbs of bogus bling. It goes like stink now, pulls real fast & hard-BUT- I haven`t touched the muffler. It`s quiet, real quiet, and my ears seem to have actually lost that high pitched ringing I was getting when I climbed off of all my old bikes. Yesterday I decided to scope out this old colonial cowpath of an abondoned road I been checking out- so I pull in the clutch and coast downhill [motor`s still running] on to the wooded trail, where upon I spy this beautiful young buck [whitetail], rolled up to less than 10 feet away and stared at this dear for maybe a half a minute til he finally noticed me and bolted! Now thats quiet, eh? I think maybe instead of spending the $$$ on a loud and fancy chrome can, maybe I should be looking for a good deal on a sturdy luggage rack and a shotgun. B |

Title: Re: Ain't whistling dixie no more..... Post by josh85716 on 09/22/07 at 22:04:19 nice job! i mounted my exhaust with a car clamp, for good reason too, i need to fix the motor, but cant run it when it was straight piped (stupid sound laws) |

Title: Re: Ain't whistling dixie no more..... Post by Bigzuk on 09/24/07 at 10:19:53 T-Mack1, Your pipe looks good. But I'd like some information on the luggage rack? Can you let us know who makes it? Thanks, Bigzuk |

Title: Re: Ain't whistling dixie no more..... Post by Rockin_John on 09/24/07 at 12:35:23 Nice looking pipe & install. I'm wondering if you looked through it before putting it on, to see what kind and how much baffling it had in it? I ask because I've got a similar looking turnout style muffler, except mine has about a foot of straight pipe before the muffler. Mine is really loud! So loud that I didn't leave it on but a couple of hours. I don't want a pipe so loud that it makes my ears ring when I wear my shorty helmet. So anyways, I looked through mine, and all it has is one little round tab of metal sticking up from the side wall to act as a snuffer, and that's all it has for baffling! You say your turnout is a "Dyna" but I have the straight type Dyna muffs on both of my Savages, so is yours a Screaming Eagle, or just a different model Dyna muffler? I'd sure like more details on exactly what yours is...? I sure wish there was some way for all of us to quantify how loud our pipes are, short of everyone having to buy a sound level meter! |

Title: Re: Ain't whistling dixie no more..... Post by T-Mack1 on 09/24/07 at 13:15:07 First, took the main jet to the 152.5 jet. After a long ride Sunday, it was a bit hotter than before. Now has more power definitely. The Luggage rack is from a friend. They took it off a Honda CB750 (fm the '70's) and stuck it on a shelf for 20 years. But.....it's a universal luggage rack because of the sliding back bracket. It originally had a sissy bar & pad (adjustable) but that went on my former bike ('82 Honda CM250C). After I cleaned the dust, found the chrome near perfect. I would search Ebay. Try using the search text " Honda sissy bar ''. http://www.users.fast.net/~tommack/Lugg_Rack.JPG It was about 2 inches too wide, so I cut a section out of the center. Yes, measured twice cut once (actually measured 3 times). I used the cut off pieces to attached the halves together. A piece of All-thread in the back pipe. http://www.users.fast.net/~tommack/Lugg-rack2.JPG see bigger pict: http://www.users.fast.net/~tommack/Lugg-rack2.JPG I had to make the bracket for the rear bracket. Used a threaded hole just in front of the turn signal screw on my '01. Used a 1/4" anodized Aluminum L-bracket and piece of medium wall steel pipe. Also had to replace the turn signal screws to clear the bracket. http://www.users.fast.net/~tommack/Lugg-rack-mount1.JPG see bigger pict at : http://www.users.fast.net/~tommack/Lugg-rack-mount1.JPG http://www.users.fast.net/~tommack/Lugg-rack-mount2.JPG |

Title: Re: Ain't whistling dixie no more..... Post by Bigzuk on 09/24/07 at 20:29:48 Thanks for the info on the rack. You do very nice work! I had a '70 Honda CB750 with a sliding back rest on the rack, so I should have noticed the look. You have made something stronger than anything I've seen on any Savage. Thanks, Bigzuk |

Title: Re: Ain't whistling dixie no more..... Post by T-Mack1 on 09/26/07 at 19:51:31 Rockin John, Sorry I missed your questions. Yes, the muffler you have sounds exactly like mine. Little tab sticking down and side wall acting as a baffle. I really like the look. It was advertised as a Dyna muffler. BUT.....I think it's a aftermarket muffler because the stamped on EPA noise warning does not say Harley anywhere. HD likes to put their name on things when they can. Loud, yes....I wear a open face full helmet so it's a little deadened. I tried to add some stuffing to make it quieter. First used some Stainless Steel "steel wool" from the grocery store. It was too thin and couldn't take the heat. Lasted about 10 miles. Monday I took it apart and tried taking some copper wire and wadded it up in the front. Couple of feet of it (14 gauge, solid, old house wire, ...Yes it was tedious to strip the plastic off). I'm pretty sure it won't last but it is a little quieter. SO, I have learned that I can add more baffle and it does get quieter. Maybe next would be getting some steel pipe and drilling a gazillion holes in it. It would take the heat. I figure the sum of the area of the holes should be equal to or greater that the diameter of header the pipe. The added turbulence should cause muffling. I just have to get motivated. A comment: I do notice that I'm shifting earlier to keep the the noise down. Only jump on it once an a while. Maybe I'll get better MPG.........keep wishing.....too much fun watch the HD riders do a double take. |

Title: Re: Ain't whistling dixie no more..... Post by MAYES on 05/05/08 at 20:28:45 My bike has a straight through pipe with a fishtail end. The darn thing shoots flames when deaccelerating. It is too loud!!I have a muffler(factory takeoff) of a Harley Sportster. Anybody have a sportster muffler? Does it sound good? Was it hard to install? |

Title: Re: Ain't whistling dixie no more..... Post by buttgoat1 on 05/06/08 at 09:20:23 I put on a similar turnout (screamin chicken something or another............) and the only baffle was a perforated piece of metal set at an angle in the main bore. I fabbed up a baffle to put a cross piece directly inline with the headpipe. I cut and bent a piece of tubing so that there is a 1-1/2" round piece for the sound/gases to hit and hafta go around. I may eventually get a baffle, but I did this while it was still easy on and off. I tried posting some pice but had trouble. |

Yep, that's sounds like my ear popper. I cut up some muffler pipe I bought at Auto-Zone, then drilled holes in it and slide it down the intake side. helped a little. I was thinking of adding a baffle in the output side. I cut a cardboard template (round circle with 2 tabs). Just have to think of what metal to use. |

Title: Re: Ain't whistling dixie no more..... Post by Mr. Hyde on 05/06/08 at 10:49:53 When you're buying an HD muffler off of e-Bay you should ask the seller if the baffles have been punched out. With the guys I rode with it was standard practise to take a pipe and drive it down the muffler and through the baffles. |

Title: Re: Ain't whistling dixie no more..... Post by jomiyo on 05/06/08 at 11:07:43 Mayes- if you are loosing that fish tale pipe, i might be interested in keeping it out of the garage for you. |

Title: Re: Ain't whistling dixie no more..... Post by Ed L. on 05/06/08 at 13:38:08 Mayes, if you switch to a sporty muffler drill a 3/8 inch hole in the baffle, brings the volumn up just about right and gives a good crackle when backing off from speed. |

Title: Re: Ain't whistling dixie no more..... Post by MAYES on 05/06/08 at 20:39:44 Hey Ed L. thanks for the tip,I don't want to lose the deep rumble, just trying too quiet it down alittle. Jomiyo, I'll keep you posted. |

Title: Re: Ain't whistling dixie no more..... Post by T Mack 1 on 06/19/08 at 08:11:55 My home made baffler has bit the bullet. The bike was getting louder and louder and the mixture had to be adjusted and adjusted. So..... for the time being I switched to a Stock Dyna take off. Don't like it.... too quite and the bike no longer has a unique sound. Sounds like every other bike..... :-[ But..... will be making a baffle out of all steel not copper this time.... and welded. Just have to get motivated...... |

Title: Re: Ain't whistling dixie no more..... Post by sidny4 on 07/24/08 at 00:12:13 I made a lollipop baffle. I just took a bolt with an eye hole, two washers, a smaller bolt and it's corresponding nut. I used the washers and the smaller bolt to block the eye hole, then I put a hole a few inches from the end of the muffler. I put the eye hole bolt through and tighten. It did help deaden the noise a bit. |

I've got two sportster mufflers. Just today I pulled off my unaltered sporty muffler, grabbed my extra sporty muffler, popped out the baffle plug so that it's straight thru, installed it and went for a ride. It sounds much better to me. It's not too loud. WOT in 1st gear is getting up there in volume a little but the other gears, highway riding, etc., it's not too loud in my opinion. On a scale of 1 to 10, with the volume of a stock S40 muffler at 1 and header only at 10, it's about a 5. I've certainly heard louder, baffled aftermarket mufflers. Anyways, I figured if I didn't like it I'd just throw the other muffler back on. But I like it a lot and will keep it on. |

Title: Re: Ain't whistling dixie no more..... Post by matt_savage on 03/25/09 at 09:46:37 How did you pop out the baffle plug? I've got a stock sporty muffler I was planning on putting on and drilling a 1/2 hole in the baffle. But if I can just pop out the baffle easily and be done with it I will. TIA -Matt |

Title: Re: Ain't whistling dixie no more..... Post by diamond jim on 03/25/09 at 09:58:13 After riding with it and making the new longshot, I realize that Ed L.'s idea of drilling a 3/8" hole is probably better. But, if you want to try it, here's what I did. I got a 2" section of heavy pipe that was just a hair smaller in diameter than the inside of the muffler exhaust tube. I put a piece of 2x4 on the garage floor, set the pipe upright on it, inserted the pipe and went to banging with a 3 pound sledge hammer. It took a lot more pounding than I thought it would. But it came out. It's much louder with the piece fully removed. My DIY longshot isn't at loud as the modded HD muffler. |

Title: Re: Ain't whistling dixie no more..... Post by verslagen1 on 03/25/09 at 10:26:04 From what I've read, silencers for firearms are made with several expansion chambers. And in performance expansion chamber for 2 stokes the idea was to size the chamber to reflect the sound wave back so that the flected wave at least partially cancelled out the new one. |
