220 4-1 manifold and HJS HD 200Cell Catalyser
The 2bular 4-1 manifold + the HJS HD catalyser combine to release some serious gains in power AND torque. A tricky task as the standard torque figures were very good to start with.
The factory manifold design is very poor for a supercharged install and the stepped 2bular 4-1 manifold is a vast improvement. Adding a catalyser is always problematical to achieving best power but the big HJS HD version ensures you can meet all emissions tests and still gain +32bhp.
The ECU mapping was carried out at Komo-tec and a specific 2bular tune is available to download.
