What would it take to get a m8 exhaust to fit on a twin cam touring bike. I understand the inlets are different size. How much else is different

 

For starters, I believe those bikes have different frames.

 

Why would you want to do that?

 

I think the cylinders/heads are taller, probably mounting angles of the ports are slightly different too. And, the muffler lengths may be different.

 

the cylinders are different an on the touring models the left exhaust is different diameter than the right where as on the TC they are the same.

 

Mufflers are tuned to the motor. So, putting M8 mufflers n a 103, even if you have to Rube Goldberg them, is a bad idea.

 

 

Thanks for everyone’s help on understanding the difference. I find that sometimes when I’m looking at buying used parts I might not get the whole truth. Better understanding help make better decisions.
