i went to auto research center ( http://www.smogcheck.com/ ) and had no problem. they did check that i had the carb numbers for my intake (but it has the sticker on it) so i don't know if you have that stuff. i don't have a swap or anything, so i don't know how that'll go, but they were really cool (especially about my car being so low. no problem with that at all). so i would reccommend them (there's also a coupon on their site for $8 off so make sure you get that).
