Release the flow fron the new Ford Mk7 Fiesta ST180 Ecoboost engine with an R-Sport exhaust decat downpipe.

The original catalyst and down pipe of the new Mk7 Fiesta ST 180 Ecoboost are made in one piece.
This new one piece design features a restrictive bend and very small 48mm internal bore. Under 2 inches!

This 48mm small bore is nowhere near the optimum flow rate of the Fiesta ST180 Borg Warner Turbocharger.

The larger bore size of the new R-Sport decat down Pipe is 76mm, the largest on the market it has over 100% more capacity to generate added power. This is the perfect way to add flow and power to all world variants of the new 2013 onwards Mk7 Fiesta ST180.

What is the MIL cheater Option?
The Mil Cheater elbow is a small device that relocates the secondary lambda probe (Post Catalyst), away from the direct flow of the exhaust gases. This causes the probe to read a less accurate signal which will then not trigger the ECU into recognising the catalyst is being less efficient than the ECU would allow. In short the MIL light or Decat light as some call it will be much less prone to coming on for the cat not being there.
