Default Standard cat converter

Hi everyone, i am going to see if i can book my car in for a set of extractors and an exhaust tomorrow. now i have been told that the standard ford cat's do flow very well and there is no need for a 'high flow' replacement. I was just wondering if this is true? what have most people done when they change exhausts? cheers

If you plan on doing more mods to your car then i would replace it

Seems to be most people say on a NA AU6 the current CAT would be fine.

thanks guys. other than maybe an edit, thats all i am planing to do mechanically to the car for a while, if at all. so it will stay NA and just have the exhaust. the main reason i ask is that from what i know the cat is fairly expencive to replace.

Just got the standard cat in mine too and seems to do the trick and your right, i was quoted $300 for a high flow cat and couldn't justify the cash.

The outlet on the rear of the cat is is only 2.25 inches get them to change that to 2.5 inches. This is what Jim Mock Motorsport do to them. I had it done to mine when the sports exhaust went on.
