Modern Horsepowers stainless steel 1 7/8" longtube headers and 3" Mids feature 321 laser cut flanges, 304 primaries, 316 high velocity merge collectors, 316 back purged TIG welds, 02 extensions, clamps, and 3" 304 mids without metallic substrate cats. Everything needed to install on the spot is included. These systems require no cutting or welding of the OEM exhaust to install; they mate to the factory catback at the OEM mounting point (factory "resonator" or mini H-pipe). All components are 304/316/321 stainless steel and carry a lifetime warranty on all materials and workmanship.

When paired with the MHP V3 CDT tune (Not Included with Header Purchase), the Mercedes-Benz 63 AMG shows gains of 115rwhp and 75rwtq.
