    Welcome! Everyone has their own opinions when it comes to exhausts on these cars. Some will tell you to stay stock, some will tell you borla, magnaflow or slp, etc. Others will tell you an exhaust spinner (turbo) is best. The general consensus is get rid of that restrictive u-bend where the front o2 is plugged into, keep some kind of resonator in the mid-pipe and the rest depends on how loud you want it and how far your looking to mod your car. If you let us know we can be of more assistance. Also a search on youtube will yield plenty of videos with all kinds of setups on our cars

    I like Full cat-backs for the simplicity of mixing and matching and imo its just cleaner. I would say Magnaflow. I have an SLP system on my 99 GTP and its a little raspy at high rpm + SLP parts you'll have to source as they dont make em anymore. Magnaflow your guaranteed a high quality system with a clean look and nice sound but your going to be paying a little more. Dynomax I have no opinion on, but they have also been around for a while and is a popular system for these cars.

    Check out black widow and Spin tech mufflers. They both sound wicked! I personally love the neighborhood haters from Black Widow.

    There is no reason to run headers on these cars.

    best exhaust is cutting and welding your own equal length primary's and secondary's headers.

    makes it sound like a pissed off 2 stroke v6 outboard
