Unleash performance in your Aston Martin DB11 4.0L M177 and Vantage 4.0L M177, including AMR and F1 Edition, with Redstar performance exhaust lower Secondary Downpipes engineered for a precise secondary cat delete. These pipes replace the restrictive lower Secondary Pipes and remove the secondary catalytic converters, delivering a direct, hassle-free bolt-on upgrade that maintains factory drivability and does not trigger a check engine light.

The meticulously flow-optimised layout improves gas velocity and lowers backpressure for quicker turbo spool, sharper throttle response and noticeable power gains, while adding a deeper, more engaging exhaust note. Specify Redstar's OEM-style heat shielding to cut radiant heat by up to 80%, helping protect nearby components and supporting turbo longevity during sustained performance driving.

Crafted from 2.0mm wall 304 stainless steel and 100% TIG welded and back purged, each system uses OEM-spec V-band flanges with all brackets and mounts mirrored from the factory unit for reliable sealing and fitment. Designed as a true bolt-on solution, Redstar downpipes integrate seamlessly with the OEM system to deliver a durable, high quality performance exhaust upgrade for the Aston Martin DB11 and Vantage M177 platforms.

Available Options

• OEM-Style Heat Shielding: Redstar's signature thermal management system reduces radiant exhaust heat by up to 80%.
