RVNG Raceworks - S63 3.5" Fatboy Race Downpipes for BMW F9X M5 / M8

For your 2018+ BMW M5 (F90) & 2020+ BMW M8 (F92) with the V8 Twin Turbo S63R Engine

RVNG S63M Stainless Steel Race Downpipes for 2018+ BMW M5 (F90) & 2020+ BMW M8 (F92) with the V8 Twin Turbo S63R Engine**

Introducing our RVNG Race Downpipes for your 2018 and newer M5 or M8! These downpipes are the best value modification available for your M5 or M8, with potential gains of up to 112 hp and 130 lb-ft of torque when tuned. By eliminating the restrictive catalytic converters in the factory downpipes, back pressure is significantly reduced, leading to faster turbo spool, increased power, and a more aggressive exhaust note.

The F9x M5 and M8 have a total of four catalytic converters—two primary and two secondary. Depending on your preference, you can retain either the factory or aftermarket primary or secondary downpipes. Unlike many competitors, our race downpipes feature a smooth mandrel-bent design that enhances flow without narrowing near the turbos. Crafted from SS304 stainless steel, these downpipes come with a lifetime warranty and our “No Hassle” satisfaction guarantee covering fitment and defects. Both primary and secondary downpipes are included.

**Features:**
- Adds up to 112 hp to the wheels and 130 lb-ft of torque to the wheels
- CNC flanges optimized through CAD/CAM, made from 304-grade stainless steel
