BMW B58 3.0T IHC CATTED 400 CELL DOWNPIPE (2/3/4/5 SERIES & SUPRA)

Sharpen the exhaust performance and acoustic tone of your vehicle with this IHC catted 400-cell sport exhaust downpipe, precision-engineered exclusively for 2019–2024 BMW models equipped with the B58 3.0T turbocharged inline-six engine (including M240i, M340i, M440i, 540i, and OPF-equipped configurations). Featuring an integrated 400-cell high-flow metallic sport catalytic converter, this performance downpipe significantly reduces exhaust backpressure to unlock faster turbo spool and increased horsepower while maintaining clean emissions and a refined, aggressive exhaust note.

Manufactured from premium SS304 grade stainless steel with precision TIG welds, this downpipe is engineered to withstand extreme exhaust gas temperatures and high boost pressures. Designed as a direct bolt-on replacement for the restrictive factory downpipe, it offers seamless integration with both OEM and aftermarket exhaust systems, optimizing underbody gas flow and thermal efficiency for a superior street and track performance setup.
