BMW 230i Performance Exhaust - Dinan - Axle Back - Polished - 2017–2021. This precision-built system delivers a refined daily demeanor with a confident growl under throttle.

Designed by Dinan to reduce back pressure and improve flow, the Free Flow axle-back produces gains of up to +4 hp and +3 lb-ft at 6600 rpm. Constructed from 100% 16-gauge 304 stainless steel, it resists corrosion and is tuned with drone-abatement technology to keep low-RPM cabin resonance in check. It bolts on using factory brackets and hangers, includes mounting hardware, and removes the factory computer-controlled exhaust valve. Twin 76 mm (3 in) polished, laser-engraved tips complete a purposeful look.
