Ships Direct from Manufacturer

This is the COBB Tuning 3in Stainless Steel Cat-Back Exhaust System which has been designed to improve the performance, the looks and the sound in your vehicle. This exhaust system has been designed with minimal bends which will help reduce turbulence and back pressure for increased horsepower, torque while improving throttle response and reducing turbo lag.

COBB Tuning fabricated this exhaust system using quality 304 stainless steel materials which will last the life of the vehicle and will endure the elements. The piping has been TIG welded and the exhaust gasses will go through a combination of 3in and 2.5in piping diameters. Exhaust hangers are welded onto the OEM locations on the piping so that no further alterations are required on the chassis of the body for fitment.

Hardware, as well as a gasket, are included to make this exhaust system ready for installation. It is also compatible with the stock, or COBB Tuning downpipe.
