New Problem: Exhaust Pops between shifts and hard decel
It didnt do this before, running FLPs, !cats, magnaflow catback. It was always smooth as can be, but the other day I was damn near out of gas (just got back from Hot August Nights the day before) so I didnt let the car warm up very long and drove it to the gas station. (didnt get on it)
Now the exhaust pops between shifts, did I break a spring, foul a plug? Thanks

Mine does this fairly regularly, and I guarantee you your car did this before your FLPs, !cats, and magnaflow, it just got muffled by your stock exhaust. If you don't let the car warm up all the way and get on it, it is going to do this because you are still in open loop and your car is dumping in fuel indiscriminately, which is igniting in your exhaust when you let off the pedal.
You can help keep it from doing this when you are running closed loop if you have Edit or HPTuners, but people with a modded exhaust usually get to deal with this. How bad do you think it would scare your average owner that isn't used to this type of thing?

Well no it didnt do this before. I know my car fairly well and know when there is a difference. After I filled the car up and it warmed up all the way it still pops, and I mean a lot of pops. This is definately something new. Hell I've had the exhaust on for over a year, never heard it pop like this. Sometimes I would shift and I might get one little pop every once and a while.

mine did the popping thing. and i found what was wrong with my car.
it was one of the spark plug wires that was not on the spark plug all the way. i just pushed all the plug wires on a little bit harder and it ran fine after that.

Mine does this also at times and im sure most of the backfire/popping is small exhaust leaks at y-pipe to collector connections and also at cat back to
y-pipe fit. I figure the fix is using muffler cement or putty on all slip fit connections. Any exhaust leaks let air into exhaust on de-accelleration, and this causes extra combustion in exhaust that you can hear.
