I bought a set of Rinehart slip-ons for my 09 SG. The add says they fit 95 thru 10 baggers. I just went to install them, and there is a huge difference in diameter between the Rinehart and the stock muffler. Do I need a gasket and a larger clamp, or different pipes? The length seems fine. As you can see the Rinehart is on the right.

 

Seems you bought a set that fits the Rinehart Tru Dual headpipes. Not the same size as stock headpipes.

 

Yeh, the add said they fit tru duals or stock. I e-maild the guy, I guess we'll see if he is a stand up guy, and does the right thing...I hope so.

 

I think once you install them and tighten the clamp you will see the diameter collapse around the pipe and you will be fine. The inlet should be about 1 3/4". Do not know the diameter for true dual mufflers, but I think they are the same. As far as clamps. My opinion is you can reuse the stock clamp, but I the manual says to replace the clamps

 

I dont believe my stock clamp will even go around the Rinehart. I didnt measure it, but I think we are talking like a 1/4 inch difference in size.
