Hi all this topic is probably an old but new here and live in Australia so parts are bit hard here to get easily. I have a 2007 Mustang GT 4.6 converted to right hand drive lol running an eldelbrock supercharger. i am having custom long tube headers made here ceramic coated and 3 inch exhaust with x pipe.
i only drive this car on weekends so its not my daily driver so my question is should i leave the cats of or should i just get high flow cats installed, there seems to be a lot of debate on this topic and sometimes not that clear.

Thanks for any input.

Craig
