midland is prob the best plus they aint that busy like most of the others are. depending what type of permit you're after. modification permit ~$30; general inspection ~$53; second time inspection ~$34; movement permit (if you ever needed one) ~$15. you'd prob be aiight with your exhaust but yea depends who you get. my mate had his checked at midland 2xdual exhaust which is pretty loud but they passed him
