Elevate your BMW’s performance with the Palenon Performance Version II BMW B58 Downpipe. Specifically engineered for 2020+ Toyota Supra 3.0T and 2016–present BMW models—including the 440i, 340i, M340i, M440i, M240i, X5 40i, Z4, 540i, 640i, and 740i—this high-flow downpipe significantly enhances turbocharger efficiency by replacing the restrictive OEM catalytic converter.

Crafted from 4.5” 304-grade stainless steel with precision-formed smooth radius bends, it promotes faster turbo spool, increased horsepower, and a deeper, more aggressive exhaust tone. Designed for straightforward installation, it integrates seamlessly with both OEM and aftermarket exhaust systems—making it an ideal upgrade for enthusiasts seeking maximum performance and sound.
