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.

Installation of this part on a vehicle that is driven on public roads outside the UK may violate other territories laws and regulations relating to emission requirements and motor vehicle safety standards.
The quality of the materials and the welds are excellent. However, I purchased this as a stand-alone item with the intent to fit to the Borg Warner EFR7163 turbo (as supplied in the m520 kit). If you're planning on doing the same, be warned, it doesn't fit! The downpipe for the 7163 turbo uses a v-band rather than ****** adapter and the pipe itself has a more acute angle bend to access the larger turbo. Otherwise a great product.
Which is why we supply a v-band downpipe as part of the m520 upgrade, which you can also see in the m520 kit shots.
Build quality is excellent as would expect from Mountune performance parts. Waiting to install and connect to the V3 exhaust already fitted
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!!!)
