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.
Recommended to fit in conjunction with mk7 Fiesta ST Cat Back Exhaust.

I recently purchased this part for my fiesta. Wow, superbly made.I am an engineer, worked in cnc machining, fabrication and toolmaking and like all mountune parts it is real quality. Only shame is i was not allowed to mount it on the wall at home. So it had to go on the car! You get what you pay for and this part matched to the cat back is a joy to have. Great sound, great quality, great service. Thanks Mountune.
Fitted as the last piece of the Mr230 kit.it really is a stunning bit of kit, it’s a shame you can’t see it once fitted. The exhaust sound so much nice now. It sounds deeper and burbles loads. Well done Mountune
Excellent service as always from the guy's at mountune, quality you can trust in, will be fitting the sports cat very soon
