Project Red MK7 is undergoing for Stage 1 modification on our editor’s 2011 Fiesta MK7 Powershift. Still on testing stage. Mods done are custom cat-back exhaust with twin exit tail pipe (Milltek sound & style), sport cat, 4-1 headers & J1 Automotive Air Intake.
Notice a drop performance on acceleration in low end. Slight power comes in mid-high end but not good enough (is my feet too tame to the pedal all this while?).
Might need some exhaust back pressure or a larger diameter exhaust piping? Dyno is needed for sure!
Low fuel consumption which is great for daily drive!
