The mountune downpipe / sports cat has been engineered for the mk3 Focus RS to reduce exhaust back-pressure at the turbocharger, allowing faster response and additional power.
Features include a large diameter 5” motorsport-type, 200 cell count metal substrate honeycomb catalyst, to ensure 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.
Features:
Recommended to fit in conjunction with mk3 Focus RS Cat Back Exhaust.
