Our performance and sound pipes bypass the stock Mercedes resonators for increased exhaust gas flow, reduced back pressure and improved sound.

Combined with RENNTECH's ECU software and stainless steel headers, our sound pipe produces noticable gains and improved power in the mid-to-high rpm range.

High-strength T-304 stainless steel construction ensures lasting quality and a rich, consistent sound.
