Designed as a direct, bolt-on replacement for the factory downpipes across 2015-2021 models, this system unleashes that distinctive AMG V8 character with the burbles and crackles enthusiasts demand.\u003c\/p\u003e\n\n\u003cp class=\"redstar-intro\"\u003eBy relieving backpressure and improving gas flow, Redstar downpipes sharpen throttle response, promote faster turbo spool and unlock meaningful power gains. Under-bonnet heat is also significantly reduced when specified with Redstar's OEM-style heat shielding, cutting radiant exhaust heat by up to 80% to help protect surrounding components and support turbo longevity. The result is a cleaner, more assertive exhaust note that elevates every drive.\u003c\/p\u003e\n\n\u003cp class=\"redstar-intro\"\u003eBuilt to Redstar's exacting standards, each assembly uses 2.0mm wall 304 stainless steel, is 100% TIG welded and back purged, and interfaces via OEM-spec flanges with factory-style brackets and mounts.
