hey guys
so when do you guys hear backpressure pops in your car? i have 3 inch exhaust the only time i really hear backpressure popping is if in low in rpms and just cruising and then let off, like 1500-2000 rpm.
i also hear CRAZY popping when i shift fast in high rpm from 2-3. it sounds amazing. i'll bring second to like 6200, and then shift fast, get back into it, and all i hear it pop pop pop. i reallly only heard it the other day for the fist time while going through a tunnel. it sounded awesome.

do you guys get any sound like that??

it's because now you're running even richer than before and the popping is all the extra unburnt fuel. If you did a PCM reset by disconnecting the battery for a while then resetting the fuel trims it wouldn't do it again for a while.
