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. NO OTHER CATALYSER WILL DO THE SAME JOB AS EFFICIENTLY AS THE HJS HD DESIGN.

https://www.rrrengineering.co.uk/ have been working with https://www.facebook.com/joetaylorracing/ to develop their stand-alone ECU for this install. Joe has had real success on track and this R&D will ensure a superb product to integrate with the 2bular exhausts for this car.
