Removing the restrictive primary catalytic converters entirely hugely reduces back pressure, improving engine breathing for faster throttle response, increased power output and a more aggressive exhaust note.
Made from high-quality stainless steel, the downpipes mate to standard or aftermarket exhaust systems and come wrapped in heat-reducing covering. Includes AIRTEC Motorsport laser-cut plaque and full fitting kit. Fits G87 M2, G80 M3 and G82 M4 (left and right-hand drive).
Note: Sold for motorsport and off-road use only. ECU recalibration required to prevent EML illumination.
