I am wonderin if a can that people put on there car would work on a bike???

Well, I am sure that somebody could make it work(Pablo).  But there are so many cool cans that are MADE for motorcycles (even the GS), that begs the question: "Why would you try?"  

It is likely that such an experiment would lead to "infinity" of carb jetting problems, poor performance, and crappy sound.  

Let the hot rod cagers put Supertraps on their Willy's coup.  We'll stick with Wileyco., Cobra, V & H, et al..

I'm pretty sure that you could use the same jet settings for any other aftermarket can.  I mean, the WileyCo would have the same amount of back pressure as a car exhaust...proly even less.  I'm sure you could get a pic posted at www.ratbike.org with it.

Check out these headers, speaking of wierd ass exhausts...

I wonder what that piece of ......art sounds like.
