QR25 Header and passing emissions

[Joshua Gary]

I have a question for a brainiac or two out there.  I've heard that removing
the QR25's exhaust manifold and the built in precat with a header will cause
it to fail on emissions tests.  I've been thinking of getting the AEBS
header.  I'm thinking if the state(Texas) ever started doing emissions
testing here; I would just buy a high flow cat and get it welded onto the
exhaust somewhere down wind of the second primary cat that is already on the
car.  I figure adding a second high flow cat would allow the car to pass
emissions(I think) without hurting performance too* much.

Do you guys think this would work the way I think it would?  What do you
think of this idea?

Thanks,
Joshua
