crackle exhaust

[helliviknow]

hey guys i just got my hp racing catback exhaust on paired with my tsudo header n downpipe. only problem was i had to reuse the stock cat for now till i find a hi flow. this exhaust was somewhat quiet and then i yanked the silencer out and bout shit myself when i started it. thing is loud. real loud. its not as ricy as i thought it would sound but its close. heres my issue. when i let off the gas or downshift it crackles and sounds sounds sound very choppy.. is this normal with the 420a with an exhaust or u all think its the stock cat? peace

Happens on all cars.. well I am not sure about all but a majority of them yes it is normal. It happens on my friends V8 just not as crackly. My solution don't downshift put the car in neutral

Happens more on some cars, especially horizontal engines.. Maybe not more, but louder. I think it sounds mean, but in any case there's not much you can do about it.
