Popping Exhaust... Cause? A week or so ago I pulled my rockers and such to check my pushrods. Pushrods checked out fine so I put everything back together.
Car has been ran for about 800 miles since, from a trip to Panama city and such... but yesterday and today I seem to have a problem. My car would always pop when I would decel, from backpressure building in my custom exhaust system.. but now its a much worse problem. If I rev loud, it'll pop a few times as the RPMS come down.. its a very quick pop.. not like backpressure building. If I bring hte RPMS down from anything over 4 grand it'll pop... sometimes once and sometimes 2 or three times in sucession.. its pretty loud and quick.
Could a loose rocker.. or something I didn't put back on the car cause this?
The car is also quieter then before... yet still very loud. I switched back to the stock MAF.. could this cause the fuel mixture to be off and its just slowly fixing itself?

prob just running rich for one reason or another. Check and make sure you have no obvious leaks around the maf or lid. If still no go get some atap or a tech II on it and see what your ltrims are at.

. Loud as hell, but has a great tone and sounds bad ***. I'd say the popin is normal, just back pressure building up. By the way, when did you go to panama city beach, i was jsut down there last week for spring break. It was tight as hell

My custom exhaust is LT headers !CATS and 2.5" true duals.
I've always had the backpressure pop.. but this a few quick pops when backing off the gas... and it has just started.... *shrug* car still feels pretty strong I guess.

Yea it did, I've since removed the ones on the side, but kept the actual stripes.
Don't remember your car... but there was so many cars it was hard to keep up.

Atlanta GA.. just below Atlanta rather.
It was only about a 4 1/2 hour drive cruising 85mph the whole way.
