If your muffler is still intact you should be able to keep bending it until you get it to a point where it works. I usually take 4 or 5 tries at it before I get the muffler where I want it. A poo-poo pipe will need adjusted also. There is no such thing as "one size fits all" with these bikes! Good luck!

If you need to put a slight bend in your stock exhaust, I will give you a great tip on how to hold it down when you bend it.
Use an old piece of steel plate, channel Iron, anything you have laying around. Drill the hole pattern that fits your muffler in it. Bolt it down solid with a couple 6 mm or 1/4" bolts. Clamp that in the vise and bend away, That way you can give it a little bend without it pulling out if the vise.

That's not me. It is the "Gyro-Captain" from the second Mad Max movie.

I generally clamp the flange from the muffler assembly in my vise and use that to hold one end still while I heat the pipe and try to shape it.

That's ok if you only have to move it a few 1/100ths but not practical for any larger distances.

Good idea, John. I put two 1/4" bolts in the vice, really tightened it and that worked too.


Beetle,
You can weld, (solder) copper to steel. If you know anyone in the air conditioning trade they use a product called, Silv-Aloy. That's a brand name, there are others. It is a high temperature solder alloy used in refrigeration piping. It is a type of silver solder that takes high heat to use and some practice to master. You'll need an oxy-acetylene torch or one called a Turbo-Torch to achieve enough heat to flow the stuff and it requires a special flux. A good air conditioning guy will have some on his service truck and if you offer him a beer he might do that soldering job for you. Plumbers don't typically use it but air conditioning / refrigeration people do. Good luck.
Tom

they sell a muffler adapter(it looks like a 1" thick gasket made out of aluminum). you could make one yourself. on mine im going to use a 1/2" gasket to move muffler away from my peddals and the muffler will tuck right next to frame.
