Default Best Flowing 3" Cats?

Who makes the best catalytic converters? Thinking about getting some hooker headers with x pipe and keeping it emmisions compliant.

Dyno'ed at 366 hp with ORY, then added the Random Tech's and then dynoed at 366 again.

I think I lost like 2 flb of torque.. but still not bad.

See the Winter 2002 edition of the Hot Rod publication ENGINES

...they have a comprehensive flow test for all the aftermarket CATS...it is in the LS1 article about bolt-ons that SAM tested...
