RVNG 6” Gen 3 B58 Downpipe – The Largest on the Market

Fits all Gen 3 B58TU2 models

Unleash the full potential of your Gen 3 B58-powered BMW with the RVNG 6” Race Downpipe, designed specifically for the latest B58TU2 engine platform.

Most Gen 3 B58 downpipes on the market use a 4.5” or 5” design. RVNG takes it a step further with a massive 6” inlet, giving your turbo more room to breathe and a smoother path to evacuate exhaust gases.

The difference is more than just size. A 4.5” downpipe has roughly 15.90 square inches of cross-sectional area. A 5” downpipe has roughly 19.63 square inches. Our 6” design provides roughly 28.27 square inches of area, giving it about 44% more flow area than a 5” downpipe and about 78% more flow area than a 4.5” downpipe.

On a turbocharged car, restriction after the turbine is the enemy. By increasing flow area and reducing post-turbo backpressure, the RVNG 6” Gen 3 B58 Downpipe is designed to help improve turbo efficiency, support better response, and provide more headroom for higher-power setups.

Built from premium 304 stainless steel, TIG-welded for strength, and finished with CNC-machined flanges for OEM-like fitment, this downpipe was designed, tested, and proven in-house by RVNG RaceWorks.

Whether you are chasing high horsepower or simply want the best-flowing bolt-on option for your Gen 3 B58, the RVNG 6” Downpipe gives you the airflow advantage no one else can.
