This unit was driven only roughly 12,000 miles before removal, so it has plenty of life left in it.

The 200 cell design gives noticeably better flow than the factory cat while still keeping things emissions friendly, and owners typically report a deeper, more aggressive flat-six exhaust note along with a mild bump in horsepower and torque.

Direct fit, no cutting or welding required. Please verify fitment for your car before purchasing, and reach out with any questions.
