Shoot an e-mail to [email protected] and tell him what make and model of Jeep you have. Kolak (real name is Nick Ianuzzi) can fix you up with a header, high-flow cat, muffler, and tailpipe. His prices are very good and his customer service is second to none. You can tell him that Dino referred you.
