I know Kleemann makes 200 cel cats that replace the secondary cats. I'm not sure about the primary though....

I thought I'd read that the stock primary cats in the AMG exhaust ARE high-flow?

Alot of money for little or no return.

The primary catalytics are heavy and are extremely restrictive, an identification to this is the restrictive headers and airbox setup by replacing the current headers and airsystem a 30hp gain is possible.

MRAMG1

If you check out LET's and Vrus sites, they don't get 30 hp gain on a C32 my friend, even with headers. Maybe, and I do mean MAYBE, on a 55 series, but not out of our V-6 my friend. Thats way too optomistic, IMHO.

Weight wise you might shed 5-10 lbs, but come on not even Michael Schumacher would notice that difference.

I was referring to the 55's.

Does a stock C32 runs 14 psi? If so, is that boost bled down at redline? If 14 psi is correct, and it isn't bled down at redline, then at 6000 RPM, a C32 ingests more air than a C55.

This would mean the exhaust flow requirements for a C32 are greater than a C55.

I believe Brabus makes some as well, but they're insanely expensive.
