Description
The Mountune Downpipe / Sports Cat has been engineered for the mk3 Focus RS. Its aim is to reduce exhaust back-pressure at the turbo charger. This allows faster response, and additional power.
Features include a large diameter 5” motorsport-type, 200 cell count metal substrate honeycomb catalyst. This ensures effective, ultra high flow performance in extreme environments.
Additionally, robust OE-type mounting brackets and hangers are utilized to maintain perfect alignment and OE-like fitment. Also incorporated is an 8” stainless steel flex section to help absorb shock and prevent OE hanger failure.
Supplied with adaptor sleeve to suit either the OE cat-back or Mountune cat-back exhaust.
Revised engine calibration will be required for optimal performance and may emit the EML without it (our m380 / m400 calibrations both support this).
