AIRTEC Motorsport BMW M2C, M3, M4 J Pipe



As part of our expanding BMW S55 product range, AIRTEC Motorsport are proud to launch our replacement J-pipe for the M2 Competition, M3 and M4 suitable for track or fast road use.

In original form, due to the thin plastic construction these pipes are known to split or fracture along the seam or flange even at standard levels of boost, and when pressure is increased with a remap they are even more prone to fail. Our direct replacement uprated pipe is made from high quality aluminium and can withstand any increase in boost pressure and features a CNC-machined billet flange for a perfect fitment.

Finished in powder coated black with a laser-etched AIRTEC Motorsport logo, there’s also a port for meth injection and the comprehensive fitting kit includes a Pro Hoses silicone connector, o-ring, spring clip and jubilee clips, as well as detailed installation instructions.
