Hey everyone. I just got my flowmaster series 50 muffler put on, kept stock pipe out the side, and yesterday as was playing with it, revin' up to 4k or so, and back off, then kinda hit it again, the exaust sounded like a backfire, or a crackle or somthing. Is this normal? possibly b/c the muffler is so new?

I got the orginal 40 on mine and I reved mine to about 2600rpm and when I let off the gas I heard a cackle!!!
I LOVE IT!!! hahah It's normal probably because when you rev on the engine gas probably enters the pipin and when you let off it goes back in and hs a minor explosion.. possibly?
