MERCEDES BENZ M113K/M113 LONG-TUBE HEADERS

Designed for Mercedes-Benz vehicles powered by the M113 and M113K V8 platforms, DIAVOLO Long-Tube Headers are built for customers looking for maximum exhaust flow, a more aggressive exhaust note, and stronger performance potential from modified and high-output builds.

Constructed from polished stainless steel with long mandrel-bent runners, merged collectors, and matching connection pipes, this system is designed to reduce restriction and let the M113 platform breathe more efficiently throughout the rev range.

Fitment

Fits most M113 and M113K-powered Mercedes-Benz applications, with one important exception:

W220 S-Class models are not our recommended application for the long-tube setup.

For the W220 S55 AMG and S500, DIAVOLO recommends our Mid-Length Headers for better chassis clearance and easier fitment. Long-tube headers may still be installed on certain W220 builds, but clearance issues and additional fabrication or modification may be required depending on the vehicle and exhaust configuration.
