Redstar Audi Q7/Q8 / Bentley Bentayga Hybrid V6 EA839 Downpipes
Pairs well with
Unleash performance in your Audi Q7 4M/4M.5 E839 3.0t Turbo, Audi Q8 4M/4M.5 E839 3.0t Turbo, and Bentayga Hybrid E839 V6 3.0L Turbo with the Redstar performance exhaust downpipe. 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.
A 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.
Built 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.
