Hey guys, do any of you know if MAC unequal ceramic coated shorty headers are 50-state emission's legal? Do they have the carb # stamped on them?

but check mac's website

Just FYI Mac headers have a fitment problem after awhile because the flange on them isn't solid so after you have used them and then taken them off some prying will prolly be needed to get them back on. Like already stated check their website for the info you need.

thanks for the info, I tried checking their website already and couldn't find any info about the emissions. I'll keep trying though.

if the information isnt readily available... chances are good that they are NOT C.A.R.B certified
