Im thinking of getting a full size can for my 03 and cutting it down to the size I want. One reason I want to do this is to have a short can like Ive got now but with a more power friendly design. Im looking for a NON straight through style slip on. If anybody has one for an F4ithat they think boosted torque and didnt rob them of any low end power let me know. Loud is fine. Looking for one that comes with a new midpipe as well. Willing to consider trades for my HR1 Riot Pipe.

 

Just cut the stock can down to the size you want. Member f4isvt cut his stock pipe and made it a shorty and it sounds good. Sounds like an aftermarket pipe without the high cost. Not sure if he lost anylow end or not but he keeps up with me pretty well
