Product Info
TCM B58 5" Catless Downpipe – Performance Exhaust Upgrade for BMW & Supra Maximize your B58 engine's potential with TCM's premium catless downpipe. Engineered from 304 stainless steel, this 5-inch diameter downpipe eliminates the restrictive factory catalytic converter to deliver maximum exhaust flow and reduced backpressure. Experience up to 30HP gains on stock turbos, improved turbo spool time, and noticeably faster throttle response. The smooth internal design minimizes air turbulence while the larger diameter produces a deeper, more aggressive exhaust tone. Direct bolt-on fitment requires no modifications—compatible with factory and aftermarket exhaust systems on both RWD and AWD platforms. Fits B58 and B58TU engines across 2016–2024 BMW models (240i, 340i, 440i, M340i, M440i, 540i, 640i, 740i, 840i, X3/X4/X5/X6/X7 M40, Z4 40) and 2019–2024 Toyota Supra 3.0L. Built to last with 304 stainless steel construction
