DESCRIPTION
Release Deep Aggressive B58 Inline-Six Sound & Boost Exhaust Flow.
The factory muted exhaust system suppresses the full deep tone potential of BMW G20 M340i / G22 G23 M440i B58 3.0T inline-six engine and creates unnecessary flow restrictions. Our mirror polished SS304 electronic valve catback exhaust is a perfect street and track upgrade for B58 platform owners. Equipped with optimized high-flow mid pipe and balanced rear muffler chamber, this exhaust drastically cuts exhaust backpressure to unlock smoother airflow and noticeable power gains. Dual electronic valvetronic system supports two sound control ways: wireless remote key or mobile phone app, allowing you to freely switch between quiet drone-free daily mode and loud deep racing roar at any time. Crafted with smooth mandrel bent stainless steel and full airtight TIG welds, it delivers stable heat resistance and long service life. Matched quad carbon fiber tail tips upgrade the rear sport appearance, and OEM mounting design enables simple bolt-on installation without cutting or modification.
