I have a mk2 cupra 3" cobra exhaust for sale in the for sale section if a anyone's interested.
It will also fit a mk5 golf with slight mid to the tailpipe (it just needs shortening).... Any good exhaust building company will be able to sort it
It has a single 3.5" inward rolled slash cut tip..... Me personally I prefer a single tip to the twin set up!!
Diesel cars have ruined the twin look for me as every diesel has a twin tail pipe these days
