ZZP DP and new front O2 sensor is on (new sound clips posted) - 03/24/08 09:52 PM
The install was a snap, even with 110K miles on the car. I have been putting penetrating oil on the DP bolts and O2 sensors every day for the last week. Everything came off so easily. I forgot to go rent a O2 socket from Autozone until the car was in the air, so I jumped on the motorcycle and went for a little ride. The sound is much deeper and louder. Since I had the resonator taken off when I first bought the car, the sound is now rather raspy in my car with my summit race welded mufflers. I will have the wife drive it by the house and see how it sounds. I will give it a few days to see if it grows on me, but I will probably end up getting a high quality glass pack welded in. I will be installing one on my wifes Monte Carlo probably Wednesday. I will post how hers sound with no resonator and straight thru magnaflows. I know here resonator was much more restrictive than the one on my GP, so it needed to come off anyway. Here is a pic of the old and the new.

I put a DP on my wife's Monte Carlo SS today. It has Magnaflow straight thru mufflers with no resonator and 2.5" piping. The sound stayed much the same but louder. It is not as raspy as the GP with it's chambered mufflers. I will say the GP sounds bad arse at idle, but aweful when it is cold and your accelerating. My wife drove it to work this morning and ICK did it sound bad as she left the house and accelerated easy up to 40 on our road. I am doing a glasspack ASAP.
