I have a new contact who prepares race cars, one being a clio cup car in Hampshire and Id like to get my hands on a cup car exhaust. This i can do, but he tells me (after making a few phone calls) that the whole exhaust including manifold is £925. But, after looking in my engine bay, he says that my 2001 March 172 mk.1 already has the 4-branch manifold. I looked under the cup car and couldnt see a CAT, but he tells me its there? where?! or does the manifold go directly into one? would this exhaust be road legal (they are rather loud!) and would the racing CAT also be legal? Id really like to get this exhaust soon, as the new ECU hes fitted seems to be crying out for one. Thats that group n stage one ECU i was talking about ages ago!
