Ford Focus RS MK3 de-cat downpipe AIRTEC Motorsport 70mm, stage 2 track day

For the MK3 Focus RS owner who’s done stage 1 and now wants proper exhaust flow: this AIRTEC Motorsport de-cat downpipe swaps out the restrictive OEM unit (55mm exit) for a full 70mm bore - over 50% more cross-sectional area. No flange warping, no gasket leaks, no guesswork.

• Direct bolt-on to the stock turbo and cat-back - uses OEM mounting points and hardware
• Stage 2 essential for track day or fast road builds running aggressive maps; pairs cleanly with Cobb, Mountune or Stratified tunes
• Motorsport use only - decat = no catalytic converter, fails UK MOT; not for daily driver or show car intent
