mountune Sport Down Pipe - Fiesta ST 2013-2019


The mountune Sport Cat Down Pipe 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. 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. Additionally, robust factory type mounting brackets and hangers are utilized to maintain perfect alignment and OE like fitment. We also incorporate a 6” stainless steel Flex Section to help absorb shock, prevent OE hanger failure, and a reduced chance of false knock signals causing engine power reduction.

Revised engine calibration will be required for optimal performance. This product is for off road and motorsport use only.

  • Large diameter motorsport type, high flow 200 cell count catalyst - Larger than the competition- ensures higher flow rate.
  • 3” AISI 304 Mandrel bent Stainless Steel tube with 2.5" flanged exit
  • Robust OE Type mounting bracket
  • 6” Stainless Steel Flex joint-will not damage lower exhaust hangers like others on the market.
  • TIG Welded construction
  • Limited Lifetime Warranty
