ever since i put on my off road pipe inplace of my converter and put my flowmaster on my car sounds like i am setting off 50 M80's in my exhaust pipe after i rev the car up and let off the gas.... it does it around 5500-6 rpms every time...

the popping really sounds bad.... almost like backfiring... what causes this and is there any way to stop it???

 

I've heard of people putting a Dynomax bullet muffler (resonator) on your i-pipe. This stops the notorious crackling you hear.

 

thanks, i might try that
