i am going to buy a new 8.8 rear end for a 2001 cobra. im gonna buy a cat back exhasut at the same time and i was wondering if i would buy an exhaust system for a 2001 cobra or if it would be from i different year mustang because of the change in rear ends. this is the link for the rear end. http://www.brothersperformance.com/s...m4006b373.html
