I wanna put in an exhaust on my car. 96 GT with 70000 miles. Its a daily driver and I am not planning on racing. Just looking for Great sound and a little more performance. What do you guys thing is a good way to go as far as the exhaust. Partshopper.com has a great deal on this Magnaflow. Including the rebate and free shipping I am looking at about $390. What do you think?
