  • Complete high-performance exhaust & exclusive tuning upgrade for 750+ HP. Fabspeed's X-Pipe Exhaust System with your choice of tips, HJS German-imported Sports/Race Cats, BMC F1 Air Filters, and our ECU Tune.
  • Fabspeeds OEM Style tips are available in a matte black finish for a stealthy tip option.
  • Fabspeed is dedicated to McLaren performance and through our two development vehicles (MP4-12C and 570S) we've crafted the highest performance Sport Cat Downpipe possible. We now use the highest quality 200 cell HD cat core from HJS Racing in Germany. We’ve incorporated a cast outlet pipe which allows for the smoothest possible flow, the most possible power especially when paired with a tune, and ultimately a superior solution.
  • During dyno testing on a completely stock MP4-12C, we experienced max gains of almost 96 whp and 85 ft-lbs of torque at 5900RPM, and peak gains of 60whp and 73 ft-lbs of torque.
  • Fabspeed's Performance Package for the McLaren MP4-12C includes BMC F1 High Performance Air Filters for improved cold air induction and increased power.
  • Constructed from TIG-welded high-quality T304L stainless steel with premium 321 stainless steel flex-sections and smooth cast sections for improved fit and ease-of-installation. Fabspeed is dedicated to offering the best performing downpipes for McLarens and has invested in bespoke components to increase power.
  • Fabspeed LT-Style tips are our newest addition to the X-Pipe Exhaust system. Completely made in house, we cut, brush, and weld each tip by hand and our surrounds are straight from our Flow Mach4 XDCNC 5-Axis Waterjet.
  • Keeping the heat in the exhaust maintains the velocity of exhaust gasses, allowing the turbos to spool faster while ensuring maximum power is extracted through increased efficiency. Our included heat blankets consist of a 13mm thick ceramic fiber refractory mat interior rated to 1800 degrees. Stainless steel mesh over liner covering ceramic insulation makes direct contact with the downpipes. The basalt fabric exterior covers sewn with stainless steel mesh covering all edges and high quality stainless steel spring fasteners ensure longevity.

  1. Nice fitment. Good performance gain. 5 Star Review

    Posted by on 7th Feb 2017

    Installed myself. Removing stock catalytic converters was a challenge, especially the drivers side. The new sound is very good, not too loud, not too quiet. Performance gain is very noticeable, will light up the tires at 6k rpms in 1st & 2nd gears.
