Unleash your 2020+ Mercedes AMG GLE580 or Mercedes GLS580 with the Redstar performance exhaust engineered for the 4.0L biturbo M176. Precisely reverse-engineered to optimise flow on the M176 platform, this system integrates seamlessly with factory V-band interfaces and mounting points to transform the exhaust path without compromise.
Expect tangible performance improvements from reduced backpressure and quicker turbo response, with an enhanced, more characterful exhaust note. Optional HJS HD 200cpsi or GESI GEN2 400cpsi catalytic converters are available to suit your goals, along with OPF for European emission controlled cars. Redstar’s OEM-style heat shielding option cuts radiant exhaust heat by up to 80% to help manage under-bonnet temperatures and protect surrounding components.
Built for durability and precision, every assembly is crafted from highest quality 2.0mm wall 304 stainless steel, 100% TIG welded and back purged, and finished with OEM-spec V-band flanges. The result is a true bolt-on upgrade that fits both LHD and RHD vehicles. Redstar brings motorsport-inspired thermal management and proven manufacturing quality to your Mercedes, combining performance exhaust expertise with the brand’s renowned downpipes know-how.
