Re: exhaust crackling

Is this with the flowmaster 40's? My car used to
do that when i had flowmasters too, i think its normal.
However mine was not too loud, try to post some sound clips to help determine the problem.

Re: exhaust crackling

My Flows do that, I haven't heard of any ways to stop them from poping.

Re: exhaust crackling

I found a way to get my flowmasters to stop popping. I went with a full magnaflow catback.

Nice.

I think the poping is caused by water in either the mufflers or cats...

Re: exhaust crackling

I've never had my exhaust setups pop. Been through about 4 setups now, just never flowmaster. It must be something in the muffler design.

Flowmasters just do that.

Re: exhaust crackling

Uhh.... chambered mufflers pop nowhere near as much as straight through mufflers.

I don't know where you guys are getting this one. :dunno:

It's in the design of certain mufflers. I have straight throughs on my car and it doesn't pop at all, one bit. But I have a friend with flows on his 6, and it pops like there's no tomorrow.

Re: exhaust crackling

It is in the design of a number of exhausts that when "engine breaking", it will crackle. However, some excesive crackling can be cause by an exhaust leak as well. Check all of your connection points for leaks as well.

Re: exhaust crackling

The flows on my '90 have never popped. That's also with no cats, and moving a good amount of air.

The JBAs on the '06 (also a chambered muffler) also don't pop.

Maybe it has to do with how much exhaust is (or more importantly, is not) being moved through them and how quickly it is doing so. I know if I had turndowns on the '90, it would make a damn good leaf blower...
