The biggest restriction to making high power with the M113K engine is the limited flow of the factory exhaust manifolds. Whether you want to make as much power as possible with the AMG Kompressor, or are looking to run the Weistec M113K Supercharger Systems, it will be necessary to upgrade to long tube headers.

To make for the best power possible, the headers feature 2” primaries that allow for as much flow out of the cylinder head as possible. The large primaries and proper O2 sensor placement of these headers work extremely well when coupled with our Software and Supercharger System, resulting in the best performance and drivability out of all the headers that are currently on the market.

*Actual system may be different than picture depending on chassis.

Packaged with the headers are 3” Stainless Steel Midpipes, and a 3” Stainless Steel X Pipe resulting in a bolt on installation that retains the factory resonator and mufflers.

When paired with Weistec ECU Upgrade and Weistec Modular Crank Pulley, power gains are typically 120+hp at the wheels.
