Aside from the noise of most of them, it's the look that really turns me off.
If the diameter of the exhaust system is only 2 1/2" or 3" for its entire length, how on earth can adding a 6" diameter coffee can at the very end have any effect on performance?

Don't get me wrong: I'm sure Sideshow's new exhaust sounds great and offers some performance improvement. I just think the huge can on the back is a bit over the top. All IMHO, of course.
