Finally got round to sorting it yesterday. 
The exhaust thats on there is only 1.75" and for a different car so not sure what gone on there. He didnt have the parts to change it all so just chopped it at the centre silencer and put some 2.25" pipe on with the irmscher back box and it sounds just reight. Will have to get the rest done as it drives much better with just that done. 😃
