This is direct bolt on and uses the stock hoses/couplers. No trimming or modifications required.







Dyno Results - Stock vs Evolve FMIC/Exhaust vs Evolve FMIC/Exhaust/Tune

NB. The spike at 2750RPM is caused by the car being released after being held under load on the dyno. It is not present while driving the car on the road.

WHP



WHTorque



BHP (Flywheel)



Torque (Flywheel)



Decat Downpipes next on the list.
