Hello everyone! I'm a new member and I just wanted to introduce myself.
I have a 2005 Grand Prix GXP. Love it. I lived in Colorado and I needed a front-wheel drive car but didn't want a 4-banger. The GXP worked great on the snow days! In the past, I also had a 2000 Grand Prix GTP.
A quick question...I'm considering upgrading my exhaust system but I've been told that the DOD engine won't work very well with some systems. Does anybody have any experience they can share with upgraded exhaust systems on their GXP?
Thanks!
Scott
