Overview

The MSC Performance R129 M113 SL500 Headers are exhaust manifolds designed for the R129 platform with M113 and M113 AMG engines.

These headers allow exhaust gases to escape more quickly from the cylinders, reducing back pressure. This results in higher engine power output and a more aggressive exhaust sound.
