RENNtech Sport Mufflers are made out of T-304 stainless steel (SS) and 100% hand crafted in the USA.

This exhaust system is 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.

The RENNtech Sport Muffler System for the W222 - S550 Sedan comes with an integrated valve system and utilizes the electronic OEM actuators. The system comes with all the required hardware.

Note:

• Cutting of the OEM exhaust is required. No welding required. Utilizes OEM vacuum actuators 

Gains:

• up to 10 HP & 15 TQ
