Hi,has anyone fitted a high flow manifold/cat to a JCW S?
Will it effect emissions and cause a warning light? Will it pass dealer services and M.O.T
Also are noticeable power gains achieved?
I am considering the GTT manifold with 120cspi Cat,have heard its good for 10 or 11 BHP on a JCW.

Wibbly has a Milltek manifold on his rather cool Black JCW MCS

Ive had exactly that done by GTT - Roland said it would be more like 8bhp. Sounds great, definate improvement on mid range pick up and top end. Also got a straight through replacement pipe for the cat for track days

Thoroughly recommended
