Ask loads of different traders this and got no solid replies,
My car has an American "DC sports" cat back exhaust system fitted,and now
i want too fit a sports cat to it,it is a 3" system which at the mo fits the OE second cat on my car(STI 8 uk),will any OE fitment be ok or am i looking at a new system.
Any help on this matter would be appreciated.

Just to get your current system straight, do you have a std 2.5" catted downpipe leading onto the std 2.5" 2nd cat and then a 3" system to the back?
If so then it is pretty pointless in fitting a 3" sports cat to go down to 2.5" std cat and then back out to 3".
Why keep the 2nd std cat? - it'll just bring down the rest of the system.

Hi,sorry for not resonding,bit busy.Your correct about my two standard cats and the 3" system back but i want to remove both cats.
I purchased a DC sports downpipe(3"that de cat's both) two years back but never got round to fitting it now i want to be mature and fit a sports cat!!!!
