depends on if they do a visual or if you have a "friend"...here in Md. they do/can perform a visual so I went with CARB shorties w/HF cats...btw the cats are the biggest restriction and make the biggest diff in performance/sound...period. coupled with a awesome tune from dynoSteve at RDP the car has ZERO cels, massive performance gains, 20+ mpg hwy(who the f care around town...really) and I can pass any emissions tests...

any mod you do really needs to be combined with the right tune otherwise IMHO your wastin your time/money...good luck OP and at least yer askin the Q's first rather than bitchin after the fact like many do....lulz...

I know lots of 2010 and up Camaros in mass that have headers and pass inspection.. albeit mine is an older Camaro I have headers and never once had an issue

I spoke with the owner of slowhawk performance and he said I will be fine with longs tubes and cats. He said he will intsalll the headers and cat and Dyno tune the engine/tranny for 2100 which I am pumped about. I'm hoping with those mods plus cai and tb I will be at around 360-370 rwhp and maybe a little more TQ. I cant wait to feel the difference since my 08g35xs only makes 242 and 231 tq to the wheels and the g is about 200 pounds heavier. I can't wait to finally feel TQ, it's one of the reasons I'm going with the Camaro over the 5.0 coyote. My buddy has both and say even though the 5.0 is a hair faster the Camaro feels faster and throws you back in your seat much harder.

I have a 15 L99 and with slp long tubes, cats and full exhaust, no tune had 365 wheel.. now supercharged and totally different set up. If you are interested I still have the complete exhaust I'd love to part with. SLP long tubes, cats, 3" stainless exhaust with resonators and loud mouth II mufflers. Went to a much larger set up when converting to LS3, cam, supercharger... etc
