No backpressure equals lost horsepower, sounds good at idle but sounds like someone is firing a machine gun under your car at acceleration, gets old after awhile. My opinion I've had this before and flowmasters were on my car the next day. Seems like alot of threads of no mufflers are popping up....
I have not had this happen... I can get it to backfire if I just shift the AOD through 1, and 2nd and letting off the gas.. but it isn't even that loud and it may crackle just once.... I think it sounds awesome, it is loud I agree but nothing like "machine gun under your car at acceleration"
