S63 Catless Downpipes - BMW M5/M8

Upgrading your BMW M5 (F90) or M8 (F91/F92/F93) with 304 stainless steel catless downpipes significantly enhances engine performance and exhaust flow. These downpipes replace the restrictive factory catalytic converters, reducing backpressure and turbo spool time, resulting in increased horsepower, torque, and a more aggressive exhaust note.

Key Features:

• Material Quality: Constructed from high-grade 304 stainless steel, these downpipes offer superior durability and resistance to corrosion.

• Enhanced Performance: By eliminating factory catalytic converters, these downpipes can add up to 112 horsepower and 130 lb-ft of torque, improving acceleration and throttle response.

• Optimized Design: Features mandrel-bent tubing with smooth radius bends to minimize turbulence and maximize exhaust flow. Precision TIG welding and CNC-machined flanges ensure a perfect fit and reliable performance. 

• Fitment: Designed for direct bolt-on installation without modifications, compatible with both left-hand drive (LHD) and right-hand drive (RHD) models.

• Sound Enhancement: Provides a deeper, more aggressive exhaust tone, enhancing the auditory experience of your vehicle.

• Fitment Compatibility:

• 2018–2021 BMW M5 (F90), including Competition models.

• 2020+ BMW M8 (F91/F92/F93) Coupe, Convertible, and Gran Coupe, including Competition models.

Note: Catless downpipes are intended for off-road and track use only. Installation may trigger a check engine light (CEL); an ECU remap or a delete-R module is recommended to prevent this. Ensure compliance with local laws and regulations regarding emissions and vehicle modifications.
