The 2.5-inch mandrel-bent tubing ensures maximum flow, reducing backpressure to help your V6 engine breathe more efficiently. The dual rear exit configuration features polished 3.5-inch stainless steel tips, providing a sleek, performance-oriented aesthetic that perfectly complements the S197 body style.
