Thanks, I am going to look at the rear disk conversion but will probably drive it this way for the rest of the year. I am considering the SSBC conversion or just doing a SVT conversion.

As for the exhaust see 14.10 D and 14.10 E in the 2013 rule book:

14.10 D This allowance does not permit relocation of the catalytic converter.
14.10 E Catalytic converters: Any catalytic converters are allowed, but must attach within 6 of the original unit.
So perhaps you could use a SVT header and cat since it was a similar US model, but just to be safe I went with the shorty and the cat in the same location.

I'm old and slow anyway so a couple of horsepower either way won't make much difference.
