dr_broon Posted June 10, 2013 Share Posted June 10, 2013 I've got a sports cat, I've noticed no difference between this and the de cat that's good to know always wondered if there would be. Quote Link to comment Share on other sites More sharing options...

spudley1988 Posted June 11, 2013 Author Share Posted June 11, 2013 I dont have a cat on my manifold no more. Bought a 4 branch stainless which obviously removes the cat but i then put an EJ9 cat onto the bottom of my downpipe where it would have been on an EJ9.
