Thread: Exhaust

I've got an 04 GT and I was wondering if that piece of pipe in the middle that is expanded some is the resonator

yes

and DON'T REMOVE IT.

Or it will sound like ass

Unless you like the sound of ass. Then remove it

So I removed it to see if I could hear what it sounded like when the engine shutters and it makes a popping, and it has a random pop every once in a while. I feel like there could be a miss, and also it sometimes almost stalls out when I stop. Could this be a problem with the alternator?

If you've got a random miss/pop removing the exhaust is only going to make it more noticeable, not help diagnose anything.

Check your plugs/wires, easiest thing to do to tell if theres a bad miss.

Is there a check engine light?

yeah, but when I got it read it says O2 sensor, my abs and trac are on too

I was running open DP and my car was just backfiring without missing. No Engine lights or anything.
