Akrapovic Slip-on vs GT4

s14_kev · 04-20-2013, 04:49 PM

GT4 sounds money. I have the slip on with test pipes but man that GT4 is beastly. I'm sure you do get a few extra hp out of the catless setup too. Are GT4 x-pipes hard to come by?

Why not just code out the cold start? No need for it without cats.

^^True, I am going to try and hear the set up at bimmerfest this year. Im sure someone will have it there, at least I hope

GT4 sounds great but would be hard to live with as a daily driver IMO.

^^I def need to hear this set up in person. I can't imagine it being crazy loud but based off the post it must just be monstrous.
