SPOOL B58 5 Inch 200 Cell Catted Downpipe
SPOOL's 5-inch B58 downpipe is engineered in-house from 304-grade stainless steel with a thicker 2mm wall for strength and durability. Its 200-cell Euro 5 catalytic converter and large flex section make alignment with your exhaust simple, while the 5-inch diameter delivers a deeper exhaust tone.
Reduced backpressure supports faster turbo spool and smoother flow, and with a proper tune it can deliver significant horsepower and torque gains. This downpipe fits Gen 1 and Gen 2 B58 2-port and 6-port engines across a wide range of BMW models and the 2019+ Toyota Supra A90/A91, and it is backed by SPOOL's lifetime warranty.
