Pairs well with
Unleash the authentic V8 character of your Mercedes SUV with Redstar performance exhaust downpipes engineered for the M278 4.7L V8 BiTurbo and M157 5.5L biturbo AMG engines. Precisely developed for 2012-2015 GL450 X166 M278 4.7L, 2012-2014 ML550 4.7L V8 BiTurbo M278, 2012-2015 ML450 4.7L V8 BiTurbo M278, 2012-2015 GL550 4.7L V8 BiTurbo M278, 2016-2019 GLS550 4.7L V8 BiTurbo M278, as well as 2012-2019 ML63 W166, 2013-2019 GL63 GL63S X166, 2015-2020 GLE63 GLE63S C292, 2015-2020 GLE63 GLE63S W166, and 2017-2020 GLS63 X166, these downpipes replace the restrictive factory units to free up flow and soundtrack.
CAD-led development and motorsport-informed manufacturing focus on reducing backpressure for faster turbo response, stronger mid-range torque, and a more engaging throttle feel. Optional OEM-style heat shielding cuts radiant temperatures by up to 80% to help control under-bonnet heat and protect nearby components, while the exhaust note deepens into a richer V8 soundtrack with burbles and crackles.
Built for longevity and precision fitment, each system uses 2.0mm wall 304 stainless steel, is 100 percent TIG welded and back purged, and employs OEM-spec 304 stainless steel flanges with all factory-style brackets and mounts. The result is a true bolt-on performance exhaust upgrade from Redstar that integrates cleanly with your vehicle while delivering a decisive improvement in response, tone, and durability.
