Catback exhaust or catless downpipes
Hey guys, recently tuned my car, and now Im seeking a bit more power/sound.
Im not a power freak so it doesnt bother me to scarifice a bit of power for getting a lot more sound. I want to reduce back pressure to help my spool up and also put less stress on the turbos, so I want to get a ae catless exhaust. My question is would this reduce back pressure by a big amount, or should I forget the exhaust and just get some ar catless downpipes? I want an exhaust due to better sound and less trouble to swap oit with stock for warranty claims Do you guys think I should just get downpipes? or would an exhaust reduce backpressure enough for me to help spool up and even allow me to run map2 on my procede(it would be dci the ae exhaust and 94 octane). Thanks |

Quick question, sorry about the highjack, PM won't work yet.
How do you find using your Procede with your snow meth kit? Particularly like how i can use Stetts CP with a BOV has with the procede meth kit I'm stuck in using their CP for compatibility reasons and a DV instead. Was going to go for a proceed tune, and to keep it easy get their meth kit. But SP's looks good. |

Best though is to go with their pwm kit since is better integrated software wise.
