VRSF Primary & Secondary Downpipes for BMW M5/M8 (F90 F91 F92 F93) S63/S63M 2018+ Race/Off-Road Catless SS304 Mandrel Bent, TIG Welded, Direct Fit, Lifetime Warranty

Transform the way your F9x M car pulls, sounds and responds with this complete front and mid exhaust pipe set for the S63 twin turbo V8. This de-cat turbo pipe upgrade replaces the restrictive factory catalysts with free-flowing 304 stainless tubing, unlocking proper performance gains, sharper boost response and a far more purposeful soundtrack. It is one of the most effective hardware changes you can make ahead of a remap on the BMW M5 and M8 platform.

Why enthusiasts choose this upgrade

• Big power potential when paired with a calibration upgrade, with proven increases of up to 112 bhp and 130 lb ft
• Lower backpressure for earlier boost, stronger mid-range and harder-hitting top end
• Complete set for both turbo banks covering the front and secondary sections for maximum flow and volume
• 304 stainless construction with precision TIG-seam welds and CNC-machined flanges for a gas-tight seal
• Smooth, constant-radius pipework helps maintain exhaust gas velocity and reduces turbulence
• Bolt-on fitment for right-hand drive and left-hand drive vehicles with no cutting or fabrication required
• Backed by a manufacturer lifetime warranty for peace of mind

What you will feel and hear

Expect faster spool, crisper throttle response and a serious step up in power once tuned. The exhaust note deepens with a more aggressive, motorsport-style tone that suits the S63’s character without the rasp associated with poor-quality systems. It is an ideal foundation for Stage 2 setups and track-focused builds.

Compatibility

• BMW M5 F90, 2018 to 2021, including Competition
• BMW M8 F91 F92 F93, 2020 onward, including Competition Coupe, Convertible and Gran Coupe
• Engine: S63 twin-turbo V8

Built for performance and reliability

This kit prioritises flow where it counts. Unlike designs that neck down near the turbine outlets, the constant-diameter pipework preserves velocity from the turbochargers through to the exhaust system. The result is a freer-breathing setup that supports higher power levels once calibrated, while the quality stainless material and premium welds deliver durability under heat and load.

Proven with our customers

We have installed these on multiple customer cars and the feedback is outstanding. Owners consistently report quicker boost build, noticeable gains once mapped and an exhaust note that finally lets the S63 breathe properly.
