Changed from 3 chamber flow's to and now the car is popping and banging at 500! The car smells much richer than before but I can feel it reving much more freely? Could a change in mufflers cause a need to drop fuel pressure? I am running a 6 lb paxton edelbroc heads and a e cam?? please help thanks

all the cars that i've heard with dynomax, seem to pop, but only under deceleration, or when the rpms come down, personally i like the sound, my next exhaust is going to be dynomax.....

as far ass smelling rich, if you have an off-road pipe, then that would be the cause of it
