Precisely matched to the E839 3.0T single-turbo engine architecture, this upgrade replaces the restrictive factory downpipe immediately after the turbocharger to free up exhaust flow across these platforms.\u003c\/p\u003e\n\u003cp class=\"redstar-intro\"\u003eA big bore layout with smooth, flow-optimised transitions reduces back pressure to speed turbine acceleration, delivering faster spool and sharper throttle response while elevating overall power. The optional OEM-style heat shielding features a ceramic inner liner that cuts radiant exhaust heat by up to 80%, helping control under-bonnet temperatures and supporting turbo longevity. For high-output builds, the GESI GEN2 400cpsi catalytic converter option supports up to 1000hp with smoother flow and improved efficiency compared with factory units.\u003c\/p\u003e\n\u003cp class=\"redstar-intro\"\u003eBuilt as a 100% bolt-on solution, every Redstar downpipe is crafted from 2.0mm-wall 304L stainless steel with TIG-welded, back-purged construction, OEM-spec V-band flanges, and factory-style brackets. Motorsport-inspired thermal management and precision fabrication deliver a richer exhaust tone, proven performance gains, and the durability expected from Redstar downpipes for Audi Q7, Audi Q8, and Bentayga Hybrid owners.\u003c\/p\u003e\n\n\u003ch2 class=\"redstar-section-title\"\u003eAvailable Options\u003c\/h2\u003e\n\u003cul class=\"redstar-options\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGESI GEN2 400cpsi Catalytic Converters:\u003c\/strong\u003e The latest GEN2 series from GESI is rated to support up to 1000hp while offering smoother exhaust flow and improved efficiency compared with factory units.
