Transform your Mercedes-Benz SUV with Redstar Exhaust SUV M276 Downpipes, purpose-built for the M276 3.0L V6 biturbo engine. Engineered for GLE43, GLE400, GLE450, GLE320, GL450, GLS450, and ML450 models, these performance exhaust downpipes target the crucial downpipe section on M276-powered vehicles to let the engine breathe more freely.

By improving exhaust flow through the system, these downpipes help reduce restriction that can mute response. The result is sharper throttle feel, stronger on-road performance, and a more assertive soundtrack. Expect a deeper, more dynamic exhaust note complemented by the burbles and crackles enthusiasts appreciate, adding character to both daily driving and spirited use.

Developed by Redstar with a focus on precision and reliability, this upgrade reflects the brand's performance exhaust expertise. Built to elevate response and sound quality while respecting the integrity of your vehicle, Redstar downpipes deliver an authentic performance uplift and the unmistakable Redstar tone.
