i had a corksport 3 inch cat back. I installed the PE yesterday and it was way better.

Makes driving my car fun again. It isn't insanely loud but not stock tone. Has more torque and seem to actually run about the same (wich is in increase b/c my boost is down .2-.3 bar). I beleive it's truly a masterpeice.

i don't like the huge cannons but doesn't weight that much more than the single 3 inch SS.

i have a corksport exhaust for sale btw

 

Yea, I was debating on single or dual for a while, but after getting this Im really happy that I stuck with the duals, just because it looks and probably sounds a lot better.
