Show original supplier description
The Redstar Exhaust Downpipes are designed as the ultimate upgrade for Mercedes-AMG GT models equipped with the M178 V8 twin-turbo engine. By reducing exhaust restriction, they enhance power output, sharpen throttle response, and contribute to a more aggressive AMG V8 exhaust tone. Constructed from the highest quality 304 stainless steel with a 2.0mm wall thickness, these downpipes are TIG welded and back purged for maximum durability and performance. They feature OEM-spec flanges and utilize all original brackets and mounts for a 100% bolt-on installation. The engine type is specified as a 4.0L Bi-Turbo. Important compatibility notes: These downpipes are NOT compatible with the AMG GT Black Series. Furthermore, this product is intended for OFF ROAD/MOTORSPORT USE ONLY. It is not certified and may not be legal for use on emissions-controlled vehicles in any jurisdiction.
