Deja vu???
I am sure I gave you a "go for the 3 inch" earlier this afternoon
Make sure you confirm with them that they are talking about the inner diameter though. If the outer diameter is 3 inch then the pipe will have an inner diameter of 2.75" so you will get messed around more or less.

Have you used a gasket on the side that connects to the flexi section and was it lined up correctly when tightened???
If it does not fit then the best way around it is not by buying a 3" downpipe, it is by taking it up with the seller.
You will get more power with a 3" down pipe but is it something you want to do or just something you now must do to cure a problem that has occurred due to a part that is not up to scratch???

Send the decat back and get a 2.75 inch one. That'll sort it right out.
