I have a used Greddy from the downpipe back exhaust system in great condition (estimated 6000 miles with it on). This tip and polished muffler look great, the tubing before that is ceramic coated. I just don't like the tone it has with my test pipe. So its still on the car, but if anyone is intested, let me know so i can get working on the other custom setup, and swap them! PM me!!!
