I fired an e-mail off to BCS this morning after I discovered they didn't list anything for the Golf .:R. 
The APR exhaust sounds great too. 
John, wasn't Mikes a 'development' car?
I am sure they would welcome you with open arms to make an exhaust for you.
Mine should be here next week.

Really friendly even after I messed them around with the specs after I found I could have something else
