This premium cat-back system delivers a deep, aggressive exterior sound with a moderately aggressive interior tone while providing maximum performance benefits and proven durability.

Constructed from 16-gauge 409 stainless steel, the system features 3.00-inch tubing flowing into dual 2.50-inch mandrel-bent pipes to maximize exhaust flow.
