New exhaust

[yellowshed]

Roush doesn't have a rolling road as such, but we have a very good relationship with one twenty minutes away. They are very accomodating and I trust the numbers implicitly - we've had multiple good correlations between engines on our dynos and (once installed in a car) their figures.

washy, feel free to drop me a note if you want a health check and I'm sure we can arrange something.
