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.
Recommended to fit in conjunction with mk3 Focus RS Cat Back Exhaust.
Excellent quality, great welding. No fitment issues; typical Mountune fits like OE parts. With V2 exhaust , charge pipe kit & FPM 375 it deepens the exhaust note & turbo spools up noticeably quicker making the car even more responsive or FAF (Fast as F!!!)
