95 Cobra - Long Tube Headers question?

[Skyman]

After seeing Dustins (SaleenGTS) awesome dyno results with the long tube headers on his 93 Cobra. We've decieded to put long tubes on my buddies 95. The thing is it has to pass smog here in CA.

Is there a long tube H or X pipe with Cats available? If not , could we buy one and just have cats welded in and pass?

Thanks,

SKyler
