I found out that supersprint make a race exhaust for the 318is, so I thought I would get one, this was the easy part, the UK distributer was stating that they were not available in the UK, so I went to the italian makers direct and that told me that they had them in stock, but I had to order through the UK distributer.
I managed to get the UK distributer to cooperate, and 3 weeks after the order, they informed me that it had arrived and was waiting to be dispatched (this is a 2 part exhaust)
I received the back box today, but the connector pipe is MIC (Missing in transit) so as all the offices are closed over the weekend, I am going to have to wait till monday to see whats happening.
