This performance exhaust upgrade replaces the factory downpipe assembly to let the M139 breathe as it should, delivering a transformative step for tuning-focused builds.\u003c\/p\u003e\n\u003cp class=\"redstar-intro\"\u003eEngineered with a flow-optimised smooth transition design, these downpipes sharpen throttle response and promote faster turbo spool, while the optional OEM-style heat shielding cuts radiant under-bonnet heat by up to 80% to help protect surrounding components and support turbo longevity. Tailor your setup with high-output catalytic options, including HJS HD 200cpsi and GESI GEN2 400cpsi converters, both rated to support up to 1000hp, or opt for a competition catless configuration for maximum flow.\u003c\/p\u003e\n\u003cp class=\"redstar-intro\"\u003eBuilt for durability and seamless fitment, each Redstar downpipe uses highest quality 2.0 mm wall 304L stainless steel, is 100% TIG welded and back purged, and features OEM-spec bottom ball flanges with factory-style brackets. The result is a true bolt-on solution that integrates cleanly, is LHD\/RHD compliant, and adds a refined, more engaging exhaust tone to your Mercedes AMG.
