Exhaust backfiring

**LOCKDOWN** · 04-29-2008, 08:56 AM

I have the SLP Loudmouth exhaust like the title implies it is backfiring lately. I get it sometimes right when i start the car but it is inconsistent. I get it rarely when I let off the gas, but I read some forums that said it's normal? All I know is that it didn't used to backfire at all and it is slowly doing it more and more. It's pretty embarrassing though to be honest. Can anyone help?

there's a difference between the exhaust popping and a backfire. If it's exhaust popping then that is normal with a free flowing exhaust like a loudmouth. I would bet that's what your hearing. A backfire is more of just one loud pop and the car will stumble usually.

I would guess it is normal popping. A backfire will scare the crap out of the general population and send mothers with children into WOT.

LMAO @ mothers w/children into WOT...

Anyways, if you haven't tuned the car since opening up the catback, its probably just popping @ startup due to the idle speed the car is calling for when cold.

Shouldn't be a problem.

I have the SLP Loudmouth as well but with stock cats and have the same issue (I get some popping when I shift too) I have edelbrock headers as well. I thought it was because I have stock cats and they were holding back. But I think it is because we have a resonator instead of a muffler. Do you have stock cats and or headers?

I do have headers. I think the cats are gone (not sure though)

It does seem mostly when it's cold. But still inconsistent, like today colder than yesterday and no popping. Yesterday it did however. From the sounds of it, it is only popping and not backfiring.
