The cats or muffler have decided to pack it in with my exhaust.

I'd been considering changing them all out anyway but left them alone up until recently. Now its developed a rattling sound which is irritating and so with a decent excuse I just need to check up on cat replacements for my single 2.5" exhaust setup. I've a vague recollection that AU XR cats are big enough to do the job without impeding exhaust flow as well as being possibly cheap compared to say, aftermarket cats.
Are AU XR cats more than enough to do the job?

can't imagine the cats becoming more restrictive on a newer model....

I have the original stock EL cats. I was never sure if the AU XR cats were more free flowing.

2.5" cats on ebay for 150...... fairly cheap
