Quiet 4" turbo back exhaust

[BigRedChevy]

either you get a "finger stick", a diablo preditor, or EFI live. All three of these will block the P0401 and P0404 codes. You can also just clear the codes and try again. Sometimes the codes won't come back untill you get after it pretty hard.

i did get the codes cleared and so far so good, thats how they got thrown in the first place is by getting on it from like a 50 roll and it downshifting, which sent it into pissed off mode. time to take her easy

I bolted up a down pipe back, 4" MBRP system this weekend and it's perfect. I was tired of having loud cars and trucks, but really wanted an aftermarket exhaust. You can hear the turbo and engine just enough to satisfy the crave.
