Gaines: +15HP & 20TQ

RENNtech T-304 stainless steel (SS) sport mufflers are hand made and rigorously tested to remove any unwanted resonances in the cabin to deliver a deep sound that keeps with the character of a luxury performance vehicle.

Our mufflers with 2 3/4 inch diameter tubing offer lighter weight than the stock exhaust and improve performance by reducing exhaust back pressure, increasing exhaust gas flow and cylinder scavenging.
