I have a back box, what size is standard pipe?

[blueturtle]

Hi guys,

I have a custom chrome racing ccr400 with a 2 inch inlet
http://www.custom-chrome.co.uk/shop/catalog/product_info.php?cPath=8&products_id=77 (it used to be on my dads saab 95 for a short while but he took it off and it hasnt been used since).

My question is, what is the size of the standard 1.3 micra k11 exhaust? As I will obviously need a reducer. Im guessing its 1.5 but im not sure. And will adding this pipe effect the performance at all?

I have very little clue about this, what exactly will I need? And I dont want to cut the current pipe as its perfectly fine and when I come to sell it I would refit the standard pipe.

Thanks in advance,

its a big flange fitting blueturtle, at an odd angle, so some cut-n-shutting would be needed eh

Ok thanks, I spose I could cut it, the standard pipes are not exactly dear anyway. But still, any idea on what size the standard pipe is? Is it 1.5 inch?
