What CEL rating are OEM AMG cats?
Looking at getting a custom switchable exhaust fabricated by Hayward & Scott - they are suggesting 100 cel cats, smaller back boxes and utilising my AMG tips - thoughts?

Most OEM cats are in the 500-600 range.

FWIW, 100cpi's are going to be loud, 300s are what most aftermarket header manufacturers use (unless the customer specifies otherwise). If you don't mind the extra volume, go with 100s.

Any nice HF metal cats out there?
I remember VRP had some nice 200cel ones. I've also checked on eBay..they were all crap.
