Title: HD muffler 65747-94 install for noob-updated pix Post by Tiefighterpilot on 05/22/10 at 14:16:26 This is my first real contribution to this awesome site for Savage (s40) owners. It is assumed that you know what the header pipe and muffler looks like. The bike is 2007 S40 from California. http://lh6.ggpht.com/_wejzwuyidIA/S_hPXqkHjpI/AAAAAAAAALk/OzWBMl5MN-g/s1024/IMG_0161.JPG This is the installed muffler http://lh5.ggpht.com/_wejzwuyidIA/S_hPX1XdeKI/AAAAAAAAALo/gWHcfNPd0eo/s1024/IMG_0162.JPG No issue with exhaust being to close or at angle against the brake cable http://lh6.ggpht.com/_wejzwuyidIA/S_hPXE0dVHI/AAAAAAAAALg/XZLW93aHyF4/s1024/IMG_0159.JPG the adapter, clamps mounted. This instruction is aimed at showing one way of taking off the stock muffler and installing a Harley Davidson stock sportster muffler (part number 65747-94). This muffler has a sliding bracket (not tab) mount that can be mounted on the Savage (S40) muffler mounting bracket. Following tools and parts were used: Tools: 1. Socket wrench 2. Socket wrench extender 3. Open end wrench or adjustable wrench http://lh3.ggpht.com/_wejzwuyidIA/S_hIQ0Nr3XI/AAAAAAAAAJ4/td7CqE1sY5w/s720/ScreenHunter_01%20May.%2022%2012.10.jpg -From Clymers manual Parts: 1. Muffler sealer- Permatex 80335 Muffler & Tailpipe Sealer (rated at 2000F degree)-seem to dry and harden well (smells bad when riding until cured). $2. 2. Muffler to header pipe gasket (part 13 aka Connector). From cheapcycleparts.com. 3. Muffler to header pipe clamp (part 12) and bolt (part 10). My bolt broke while being removed due to rust. From cheapcycleparts.com. 4. Header pipe gasket (part 1). From cheapcycleparts.com 5. Harley Davidson Muffler (part number 65747-94). $40 before shipping. 6. Harley Davidson exhaust muffler clamp 1-7/8” from ebay. $9.95 before shipping. 7. Straight 3 to 3.5 inch adapter (at local muffler shop). http://lh3.ggpht.com/_wejzwuyidIA/S_hJIsPARAI/AAAAAAAAAKY/peWDmgP_Cws/s128/IMG_0158.JPG This is a 3" adapter. The diameters were custom fitted at the muffler shop to my header pipe and muffler. a. There will be a gap of .5” between the header pipe and muffler when the muffler mounting slide is lined up to the bikes mounting bracket two bolts can be used to secure the muffler. The adapter will allow the muffler to be moved back far enough to line up the muffler to the bracket, so two bolts can be used to secure. b. This is not needed, but you will only be able to use 1 mounting bolt to mount the muffler to bikes mounting bracket if you do not use the adapter to fill the gap. Also the muffler will be moved closer to the front, so it will look shorter. c. $0 to $15 depending on shop. 8. 8 Stainless steel washer for muffler mounting bracket. These were used to fill the gap created by the angle of header pipe. These washers will sit between the muffler and the bikes mounting bracket. Also 2 will be used to buffer the nut against the mounting bracket. http://lh6.ggpht.com/_wejzwuyidIA/S_hPYzUGARI/AAAAAAAAALw/xDzg9frqaVY/s1024/IMG_0165.JPG This is picture of muffler and bracket from rear of bike. Note the 3 washers (1 is hidden) directly below the muffler, and 1 washer between the nut and the bracket at the bottom. http://lh4.ggpht.com/_wejzwuyidIA/S_hPZL5bDnI/AAAAAAAAAL0/W1wn5oPlOU4/s1024/IMG_0166.JPG This is picture from top of bracket and muffler. Note that muffler sits flushed and tight against the bracket. Gaps are filled with washers. This should provide better securing of the muffler. 9. 2 Bolts and nuts to mount the muffler to bracket on frame (grade 8). This is the strongest available at local hardware store. Locking nut would be best. This is automotive grade. How to: 1. Remove Header pipe and muffler: a. Remove front heat shield (part 20) by removing the two bolts holding it on to frame. You may need to hold the bolt on the other side of bike with a wrench to get the bolt to come out. b. Reinstall the bolts that held the heat shield, as this holds the engine to frame. c. Remove nuts and washer (parts 6,7,8,9)holding the muffler bolts to frame. d. Detach header pipe and muffler from bike. 2. Detach muffler from header pipe: a. Remove bolt (part 18) to detach rear heat shield clamp from header pipe. b. Loosen bolt (part 10) from clamp (part 12) that joins the header pipe and muffler. c. Pull muffler from header pipe. 3. Clean area to join: a. Clean the area that will join with sandpaper (if needed) or rubbing alcohol (if needed). Cleaner joints will allow for better seal. 4. Test join the parts: a. Header pipe, adapter, muffler to ensure length is correct and diameters are good for a snug fit. b. Mount the header pipe, adapter and muffler to ensure that everything will fit properly on bike. Do not need to tighten the bolts. This is so you don’t have a surprise after you use the sealer. Once the sealer dries, it is very hard to take the parts apart. c. Mark where the joints meet. This will help ensure that the adapters and joints are installed in right distance from each other in step 5. d. Inspect the muffler mounting bracket on bike and slide. Note the gap. Estimate the number of washers needed to fill the gap. Gap will not allow for proper mounting. e. Remove header pipe and muffler from bike. 5. Installing the goods: a. Join the adapter to muffler. i. Put the HD muffler clamp on the muffler. ii. Apply muffler sealer inside the muffler. Do not apply sealer to adapter. iii. Insert the adapter in the muffler. iv. Remove excess muffler sealer from inside the muffler where the adapter ends before it dries. v. Finger tighten the muffler clamp. Actual tightening for seal will happen at the end when all the bolts are tighten little by little after the header pipe and muffler has been installed. b. Join the muffler/adapter to header pipe: i. Put Suzuki Muffler to header pipe clamp (part 12) and bolt (part 10) on the header pipe. ii. Install the muffler to header pipe gasket (part 13 aka Connector) on the header pipe. iii. Apply muffler sealer inside of the adapter end that will join with the header pipe. Do not apply sealer to header pipe. iv. Insert the header pipe in the adapter. v. Finger tighten the clamp (part 12). c. Installing the muffler and header pipe: i. Slide two bolts into the muffler mounting slide. Install washers to fill the gap between the slide and bikes mounting bracket. I’ve used 3 on rear bolt and 1 on front bolt. Your bike may require different number. ii. Install header pipe gasket. Use new one if old is damaged. iii. Carefully, install the assembled pipes to the bike. iv. Install header pipe bolts. Finger tighten. v. Install front heat shield. Tighten with wrench. You will need to hold the other end (on other side of bike) to turn the bolt. vi. Install 1 washer on each bolt on muffler to mounting bracket, install nut and finger tighten. vii. Tighten all bolts little at a time, alternating between the bolts. Do not tighten one area first. 1. Tighten header pipe bolts. Do not over tighten. 20lbs on torque wrench is what I read as being appropriate. I just hand tighten using a wrench on mine. 2. Tighten muffler mounting bracket bolts. 3. Tighten clamps on joints. 4. Repeat step 1,2, & 3. d. You are done (you may want to install a generic heat shield to cover the gap). I was not able to take many pictures during the installation, as my hand was a mess. I will post some after pictures and hand drawn shortly (I need to go to work to use my work scanner). |

Title: Re: HD muffler 65747-94 install for noob-updated p Post by Routy on 05/22/10 at 16:59:03 Whew !....sorry,...for me, very overwhelming. Can it possibly take that many steps to connect a muffler to a header pipe, and one bolt to a bracket ? I think this could convince a lot of people to not to even attempt it. Sorry, just tellin it from a readers point of view. |

Title: Re: HD muffler 65747-94 install for noob-updated p Post by Tiefighterpilot on 05/22/10 at 18:14:01 It looks worse than it is. Actually, at one point I wished I just stayed with my drilled stock. This was when I found out that I had to make a third trip to the muffler shop. |

Title: Re: HD muffler 65747-94 install for noob-updated p Post by bill67 on 05/22/10 at 18:35:19 So how much power difference is there in stock and the one you put on? |

Title: Re: HD muffler 65747-94 install for noob-updated p Post by Gort on 05/22/10 at 18:52:43 Mine took 30-45 minutes of light work, without the header pipe adapter. Absolutely no discernible difference in power. Just noisier. |
|
Title: Re: HD muffler 65747-94 install for noob-updated p Post by Tiefighterpilot on 05/22/10 at 23:17:03 I would agree with Gort on how long it takes... there is just lots of little things to buy and do. So a new person doing it, it seems a lot. As to the power, it feels like I have more, but I am sure its in my head. I prob won't see any power increase until I change the other end (intake) and rejet. It sure sounds nice tho. No more sewing machine whine. |

Title: Re: HD muffler 65747-94 install for noob-updated p Post by jabman on 05/23/10 at 08:16:51 For some reason the person who has not attempted the conversion is the biggest anti-dyna install member on this whole forum. |

Title: Re: HD muffler 65747-94 install for noob-updated p Post by Tiefighterpilot on 05/23/10 at 09:38:53 Just so this thread does not devolve into discussion that it was not intended to be, I would like to ask (at least for my threads) to remain civil. Thanks. Having said that I really do love the sound. It is much deeper than the stock with holes (which was inspired by Routy's post). But as I have been bitten by the Mod bug, I just can't stop thinking and planning to modify my bike... so HD muffler it was. IMHO, if I wanted to go for slightly deeper and louder sound without all the trouble of uninstalling the original muffler, header, visiting the mufflershop, order gaskets, getting bolts, as well as looking forward to rejeting... I would have stayed with the stock with holes drilled. Again, this is just my opinion and preference, if I was not bitten by the modification bug. And since I am really enjoying the modification (even with the frustration, the satisfaction of having done the work with my own hands is immense) I would eventually get to my muffler so it was matter of time. Well, I hope this post is helpful and nothing more... either to help you do the mod or help you avoid it. :) |

Jabman, I could slam back,....but I won't stoop to that level. Now, go back and read my post again, and see that it was only the long overwhelming post from a readers standpoint that I was anti about. And I tried to do it in a helpfull and civilized manner. If you are referring to the "Direct Fit" that was discussed long ago, maybe you should go back and read that better also. Yes, I was, and still am, and always will be anti about it being a "direct fit". Anybody that can read,....????? knows better, and most that have done the dayna install knows better, whether they admit it or not. No where was I ever anti about the install itself. I'm sure I could do it as easily as "you" or anybody,......and I may one day if I find a good muffler cheap. |

Title: Re: HD muffler 65747-94 install for noob-updated p Post by Tiefighterpilot on 05/23/10 at 19:14:33 I agree. Direct fit=almost direct fit... at least it my case. |

Title: Re: HD muffler 65747-94 install for noob-updated p Post by jabman on 05/24/10 at 00:32:47 the 65388-95 is a direct fit. |

Title: Re: HD muffler 65747-94 install for noob-updated p Post by Moofed on 05/24/10 at 08:45:39 Nice post Tiefighter. Too much information is better than too little. I put my 65747-94 on over the weekend. After 2 years riding with a mac muffler, the dyna pipe sounds as quiet as I remember the stock sounding. I know it's actually a bit louder, and I'm sure my new neighbors will appreciate the change. As you might expect, low end response seems improved compared to the effectively open mac muffler. No crackle/pop on decelerating like the mac liked to do, though a bit of a puff when I turned her off. I mounted it directly to the header with one bolt. I had to drill another hole in the frame's mount because the front hole was too close to the entry point for the rail mount. The exhaust is pointed towards the brake cable a bit, but there is sufficient clearance. I don't see an adapter pipe being necessary unless the mount doesn't hold for some reason. |

Title: Re: HD muffler 65747-94 install for noob-updated p Post by Tiefighterpilot on 05/24/10 at 10:05:00 Thank you. Just trying to be helpful to those who are considering a HD muffler. I agree that it could be mounted without an adapter, but it would mean drilling a hole to use both bolts or just using 1 bolt. As to the muffler pointing at the brake cable, have you tried loosening the headerpipe and re-aligning? That worked for me. |

Title: Re: HD muffler 65747-94 install for noob-updated p Post by Moofed on 05/24/10 at 10:50:35 Yes, I resealed the head > header joint and had it loose enough to swivel while mounting the muffler. I'm not too concerned about it pointing towards the brake arm more than before, and I think forcing it to point away without a 3rd pipe piece would compromise the other joints' alignment. Having good seals to prevent air leaks is more important to me than getting some soot on a piece of shiny. |

Couple questions: Were you able to use both mounting bolts? What year is your savage? Clearance to brake cable good? Thanks[/quote] If I may chime in here, mine is a '96. I didn't need to drill any holes nor make any adapter or weld anything. I used both mounting bolts. the Savage heat shield fit over everything. Muffler # is: 64941-01. Good clearance from the brake cable. This was a simple, easy direct fit and simple work, and has been done by many Savage members on this site and other sites with no issues. Your description is very helpful but I would advise everyone to attempt the install before spending money on pipe sleeves or adapters, since in the past most members have not needed them. |
