California Smog

Hi, wondering if i will pass tail pipe emissions with hooker long tubes with 59959 magnaflow bullet cats slid right over the collectors. i know i wont pass visual but i know someone lol. the car is a 98 ss m6 with a ls6 intake deleted egr and has a lid. the car passed tail pipe with the ls6 intake without egr just wondering if it will with the exhaust now. i think it should since the cats are a 3-way converter. and the smog test is an idle, 15 mph, 25 mph roll test.

Thanks

If you don't have any OBD trouble codes your car will pass the roller test.

I passed with my Kooks LT's and their catted y-pipe (also had someone to overlook that stuff). So whatever brand they use, they passed (all smog equipment still in place). And that was with a cam.
