Overview

Fabspeed McLaren MP4-12C Cat Bypass Pipes: cat bypass pipes, for the 2012-2014 McLaren MP4-12C.

Design

These pipes replace the restrictive factory catalytic converters with straight-through tubing for maximum flow, faster turbo spool and an aggressive exotic exhaust note. Direct bolt-on replacement for the heavy factory converters.

Build

14-16 gauge CNC mandrel-bent T304L stainless steel. Fabspeed reports gains of 33 whp and 24 lb-ft, and the pipes save 10 lbs versus the factory converters.

O2 spacer option

You can add universal 90-degree catted O2 spacers at no extra cost on this listing. Fabspeed says they help reduce check engine light occurrences; an ECU tune is recommended for competition use.

Use

Cat bypass parts remove the catalytic converters and are sold for off-road and competition use only. They are not legal for use on public roads in the US.
