i wanna know what the best head gasket i can get....and were

when i drive and let off the gas at high rpm's.....my Exhaust sounds like a fart fest
it never sounded like that when i got it...plus would my Air flow converter cause that

 

if it's just backfire b/c of not a lot of backpressure that not a bad thing ( look at srt-4's).... if you are completely convinced thatit'sthe head gasket, best one on the market is Cometic, i get all my parts from CIMotorsports.net but you can find them many other places.

 

maybe you have an exhaust leak somewhere.

 

My exhaust manifold is warped and leaks and causes that noise also.

 

Cometic...yup, and don't forget to get ARP head studs since you're already there...hell, just build it up, lol. I keeeed.

I'm going with an exhaust leak too. You would be blowing out smoke from the exhaust if your head gasket was "bad". Check your flexpipe, bolts that connect the sections, cat...just check the entire exhaust tract for tell tale signs of black soot escaping. I know I have an exhaust leak (albeit a tiny one) right at the flexpipe because it has scraped a few speed bumps out here.
