exhaust popping.... i have some pacesetter LT's with matching Y-pipe w/3" pipe into a 3" bullet (magnaflow) dumped just before the axle. its EXTREMELY "poppy".
will adding 2 1/2" pipe over the axle into another bullet muffler help get rid of the poppiness??? i love the sound of my bullet....just not at high rpms when it gets really "poppy".
oh yea...and it backfires if i rev it really quick???

Mine does the same thing, but not as much as you describe. I have the same exact setup, but with a Dynomax Bullet, with a 2.5" turn down. It's just really open, if you want to get rid of the pops, that might work. It just needs a little more back pressure.

Mine had it with the stock SS exhaust but was harder to hear/recognize it. Now the Pacesetter LTs and TSP x-pipe there's no hiding it but, usually only happens when I downshift and let the engine slow me down "pop-pop-pop"... You can hear it in my video clip a little. I'm not to worried... not sure if I should be though... any thoughts?

i have the stock exhaust, i used to have a popping sound when the revs were coming down (like if revving in neutral), since my tune.. no popping at all.

This is a vid, this is the old motor. The new one is a little more crisper.

ok ... good. im glad im not the only one with this. i didnt think it was a problem....just wonderin if there was a way to help make it a lil less noticeable. my second bullet should be here sometime next week and i will def be adding it after the axle.
hopefully i can "hide" it up high. like really close to the frame rail. i really love the clean look of nothing under my bumper!

the popping is the stock tune. It is PIG RICH and needs tuned down a bit and it will stop. Some guys also have had good luck with H and X pipes calming it down a bit.
