AIRTEC Motorsport's improved replacement J-pipe for the M2 Competition, M3 and M4. The original thin plastic pipe is known to split or fracture even at standard boost levels.
Made from high quality cast aluminium at 3.5" diameter throughout (vs the original 3.3"), this represents a huge increase in internal capacity to optimise flow. Features a CNC-machined billet flange, meth injection ports, and cast AIRTEC Motorsport logo. Includes all fixtures and fittings.
