Onto the exhaust - The car arrived with no gasket or support for the exhaust and a simple U-Bolt clamp i.e. in need to love.
I found a company that makes nice billet aluminum 3" exhaust supports - I was able to use that with some aluminum plate and bar stock to make a support off on the engine. It seems like its holding it well at the moment. In due course (with the help of Mike @ RC-Monster) I'll see if I can tidy up the setup.
A stepped band clamp and titanium exhaust wrap finish it off nicely.
I've bought some high temp exhaust paint and in due course will paint the box and tips to match if i decided to retain that setup. Its VERY loud - Sets my wifes car alarm off if I rev the car in the garage - LOL.
