Yes, I searched.
I currently have 3 in mak cat deletes, 2.5 in lethal x pipe and 2.5 pipe to GT500 axleback. My plan is to convert to a 3 in x pipe, 3 in pipe to 3 in mufflers. I have a GT350 manifold and tb that spins to 7800rpm. Would the 3 in benefit me at this point? I also wonder at...
That manifold inlet will only let so much air in...I'm always looking for an edge at the track, so, at one time bought the adapter and tb in hopes of doing this very swap. EVERY tuner I spoke with discouraged me from doing it, they said there would be no gain. Glad I listened, I used that GT350...
Slow for a tune IMHO. My wife's A6 went 12.33 at 113 with catback, panel filter on nittos. I went 11.88 at 116 with catback, cai and 93 tune on nittos...
