Downpipe / Sports Cat [Mk3 Focus ST]
The mountune Downpipe / Sports Cat has been engineered for the mk3 Focus ST 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. Constructed of 3” AISI 304 stainless steel mandrel-bent tubing with a CNC machined V-band flange that allows easy installation.
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.
Please Note: Revised engine calibration will be required for optimal performance and may emit the EML without it.
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 2.5” and 3” exhaust systems
- TIG welded construction
- Limited 2 year warranty*
Recommended to fit in conjunction with mk3 Focus ST Cat Back Exhaust.
*Please contact us for warranty terms and conditions.
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.
