HONDA !
Honda conversions! The need for more power than a K-Series motor. More power means a better exhaust manifold than the factory Honda design and if you want to enjoy the car on a UK track a silencer that controls the decibels without costing horse-power. If you need a catalyser to pass an emissions test without stealing some of that expensive horsepower you've just fitted, you need the German HJS HD Euro 6 compliant design.
