Scorpion Cat-Back Exhaust System - Ford Focus ST170 (Mk1) Hatch - 57.1mm
This Scorpion cat-back exhaust replaces the factory system from the catalyst back on the Ford Focus ST170 (LR) hatch. It is made from T304 stainless steel with 57.1mm (2.25") pipework and finishes in a 100mm Tuner tailpipe. This is a resonated system, which keeps the tone deep and reduces cabin drone when cruising. Scorpion lists it as fitting to the factory front pipework or Scorpion's own front sections.
Note: Suits the Focus ST170 hatch; Australia received the 3-door (2003–2005). Installation by a professional is recommended.
Features
- 57.1mm (2.25") T304 stainless steel pipework
- Tuner tailpipes, 100mm
- Fits the factory front pipework or Scorpion's own front sections
