Fabspeed Competition Catalyst Bypass Pipes for McLaren 675LT

Remove the 675LT factory catalysts with straight-through competition pipes and included thermal insulation. The assembly is a catalyst-free alternative to the separate HJS sport-catalyst product. Based in Fort Washington, Pennsylvania, Fabspeed Motorsport designs exhaust, intake and ECU-tuning products for Porsche and other sports cars. Development includes evaluation on a dynamometer, on the road and at the racetrack.

Use restrictions
