This cat-back system for the BMW G20 M340i and G22 M440i is a direct replacement for the factory exhaust from the catalysts back, delivering improved flow, more volume and a more aggressive tone. Available using the OE tailpipe trims or with quad GT-100 trims.
Please note: Designated a race product for off-road/motorsport use and not E-marked. On OPF/GPF-equipped cars this system replaces the particulate filter section and an ECU remap may be required. For an E-marked, OPF-retaining option see the OPF-back system.
