MAD B58 V2 4.5" Downpipe W/ Bracket

Upgrade from the stock B58 downpipe to the MAD B58 race downpipe for maximum airflow, power, and sound!

The Mad Race B58 Downpipe is an essential upgrade for any BMW enthusiast looking to maximize the performance of their B58 engine. Made from high-quality materials, this downpipe is designed to provide maximum exhaust flow and improve turbo spool time, resulting in increased horsepower and torque.

The Mad Race B58 Downpipe is constructed from High quality 304 stainless steel, which provides excellent durability and resistance to corrosion.
