Popping exhuast please help!
I took out the catalytic converter on my 93 z28 and the exhaust pops upon deceleration.
I have the stock exhaust manifolds and a flowmaster muffler.
Has any one else had this problem when dumping the cats. Will headers solve this problem.
Thank you

Last reply sounds good to me. But then again I have my cats and when I added my SLP loudmouth with stock manifolds and cats I too sometimes get a slight popping sound when I let off the gas after reving it up a little??? Almost like the old Glasspacks used to sound, but not quite as loud. weird...

Like Shoe Box said, it's just back pressure and the sound is more pronounced with an M6 as opposed to the A4. If headers will do anything it would make the popping louder, less back pressure = louder popping. Consider this a good thing. When my friend took the muffler off of his 00 Z71 5 speed and just ran on his cats it popped loud and hard,cool but annoying, this lasted three days and he got a flow master put on.

My friend has a 95Z with MAC headers, ORIP, stock pipe and a flow, the thing pops really loud if he revs it up to about 3500. Also when he is driving the car hard, when he shifts it pops. The car is really loud and sounds different, it has a metallic sound to it, it doesn't sound like a truck like most F bodies I have heard.

Might check for manifold leaking problems,or vaccum leaks.
I just got off the freeway tonight,and downshiffted to 3rd from doing 75mph,down to about 30mph,and no popping or nothing(smooth),since I had the map sensor fixed.Myo2.
