Downpipe / Sports Cat [Mk3 Focus RS]
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 utilised 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).
Features:
- Large diameter motorsport-type, high flow 200 cell catalyst
- 3” AISI 304 mandrel bent stainless steel tube
- Robust OE-type mounting bracket and hangers
- 8” stainless steel flex joint
- Compatible with OE / mountune cat-back exhaust
Recommended to fit in conjunction with mk3 Focus RS Cat Back Exhaust.
WARNING:
Whilst this product will pass current UK MOT tailpipe emissions regulations, it utilises a high-quality motorsport catalyst, which is therefore designated for off-road use only in the UK.
If outside the UK, please check your local territories laws and regulations relating to emission requirements and motor vehicle safety standards prior to purchasing.
