The mountune Downpipe / Sports Cat has been engineered 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.

A large catalyst cross section means increased exhaust flow compared to other smaller catalyst equipped down pipes on the market.

Constructed of 3” primary AISI 304 Stainless Steel mandrel bent tubing with a CNC machined flange that allows easy installation, whilst robust factory type mounting brackets and hangers are utilised to maintain perfect alignment and OE like fitment.

Also incorporated is a 6” stainless steel flexi section to help absorb shock, prevent OE hanger failure, and a reduced the chance of false knock signals causing engine power reduction.

Revised engine calibration will be required for optimal performance and may emit the EML without it (our m235 / m285 / m310 calibrations both support this).

Features:

• Large diameter motorsport type, high flow 200 cell count catalyst 
• 3” AISI 304 mandrel bent Stainless Steel tube with 2.5" flanged exit
• Robust OE type mounting bracket
• 6” Stainless Steel flexi joint 
• TIG Welded construction
• 2 year limited warranty*

Recommended to fit in conjunction with mk7 Fiesta ST 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.
