I bent the **** out my b-pipe yesterday on a tree root sticking out of the ground. sweet right?! SO the question is, would my 3" tanabe muffler attach to an 05-06 B-pipe with no problems because there different sizes? And would the .25-.50 inch (not sure how big the stock exhaust is)difference make a real noticeable differencedifference in performance? Thank you

 

try it and find out if it fits. No harm in that. and no you aren't going to have a difference in performance. the 05-06 exhaust stock alone has almost the same performance as an aftermarket exhaust.
