'Best" is very subjective. What are you criteria; loud vs subtle, large vs small tips, y-back vs cat-back, etc....Top Speed or Invida are ones I like to recommend as they are not too crazy regards to sound and priced well. Also check the review section in this forum and of course youtube for sound clips.

 

Then, check the Classifieds forum. You might find a used exhaust for sale by a fellow Canuckistanian.

 

Thaitanium has a group buy for exhaust in our Group Buy section. My personal opinion would be his, GThaus, Motordyne, and Ark. I like stuff more on the louder end.
