Congrats on the 13. How do you like it so far and how does it compare to your tuned GTR you just traded in? Thanks.Sorry to disappoint guys. I took off the exhaust and traded the car in for a 13. I think I am going to keep this car relatively stock. I have an aam dp, cobb, and the Meisterschaft exhaust that I am about to put up for sale in the next couple of days.
