Anyone else's car make this nasty sound?

[98Firebird]

sometimes, not all the time, when i shift anywhere past 3k rpms just cruising, i get some nasty *** BLAAHDFLOF fart kind of sound... its loud, its obnoxious, and it sounds like total **** and is really really embarrassing. i have pacesetters, 3" gutted cat, 3" piping, and ravin muffler... and it did this before headers and gutted cat as well. i hope its just not my car [img]redface.gif[/img]

Does it sound like a small backfire, like backpressure enduced?

If I think I know what you're talking about I like that sound. Here's my demonstration:

(1st gear) vroooooommmmmmmm blagegjjgs (2nd gear) vrooooommmmmm blagejsdfjsdf (3rd gear) vrooooommmmm etc...

Heh, I like how cars sound during the short period between gears. Depends on the car of course, I can't imagine yours would sound that bad given the exhaust mods you have.

I have almost the exact same setup and the exact same sound. Just change when you shift. I find 6300 rpms works pretty good. :D :D :D

6300 RPMS huh? does your motor still run?

I shift at 6500 [img]graemlins/rofl.gif[/img]

Oh yea. Ran it to 6550 on the dyno the other day. X-P Hot Cam, 105# springs, and hardened push rods make a world of difference.
