Hiya spider ive been reading through your posts about converting the audi A4 B7 2.0TFSI to a KO4 turbo, I have pritty much sourced all the parts I need, other than the fastflow cat. I dont want the hassel of a test pipe. Do you know of anywhere that makes this item that will fit the KO4 flange and sell it as an on the shelf produce. I would appriciate any advice at this time.
cheers
