AIRTEC Motorsport Downpipe Sports Cat for BMW G Series – M2, M3 & M4
£895.00
By replacing the restrictive primary catalytic converters located in the original downpipes with specially designed high-flow sports cats, or removing them entirely with our optional de-cat downpipes, back pressure is reduced, which effectively improves the engine’s breathing by allowing it to expel gases more quickly. This in return means faster throttle response, increased power output and a more aggressive exhaust note.
Complete with replacement fitting kit, the downpipes will mate to a standard or aftermarket exhaust system and come wrapped in a heat reducing covering.
