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

• Note:The RENNtech sport mufflers on the E 63 (W212 Pre FaceLift) utilize the OEM tips and need to be modified to fit our sport mufflers and will require welding of OEM tips. 

Gains:

• up to 10 HP & 15 TQ
