i love the sound of mine. i want headers so bad but i cant spend the money right now.

also have no cat, they dont check in Illinois

I'm in the same boat. I want to get an exhaust (mostly for the sound) and I want to be loud w/o having straight pipes on it. I've read the Magnaflow cat-back is quiet?? I really want a Corsa or Borla Cat-Back but to my knowledge neither make one for the Impala.

My magnaflow cat-back is LOUD, took the resonator off and cat.

It's gotta be. Even with the cat and resonator installed, mine's still loud enough to set off car alarms in the parkade at work.

I have cheap Thrush welded mufflers with the res removed and get complements quite a bit. I would like to remove my cat as well but the cost of the catless dp and tuner to get rid of the cel is a bit much given I just put in a new "used" motor and rebuilt trans.

Can anyone verify for sure that a single 3" to 2.5" dual system made for a GTP will fit on a Monte Carlo?

Catless DP --> No res --> Super44s

Rasp for days. Loud as hell. Turns heads. Sounds pissed. Stanks.

I think I decided on an exhaust. Gonna keep the stock mufflers, and get an electric cut-out from DMH right after the Res, heard a couple of them and they sound nasty. Now I gotta find someone to weld it and wire it.
