Delaware requires an inspection of the any vehicle before registering it. They will also check and see how many decibles your exhaust system is putting out. HAve know many a rider who have to put stock systems back on there bike to get it licensed. I would try and run it through with the current exhaust, maybe you will get lucky.
It can get complicated here in SC. We don't have any inspections but you can't do everything in one place either. You have to pay your taxes and fees at one place (county courthouse usually) then go to the DMV with your receipts to get your tags and pay for them there.
Many states have it so you can either do it all at one place OR...better yet...do it all on line with a card.
But I'd go into your yellow pages in the New Customer section up in the front. They usually have it all laid out for you as to what you need to do and the phone #'s to call for more info...of course THEN you have to wait forever for the menu, Spanish choices, please take our survey... :icon_blah
If you bought the bike in Ga, you don't have to take it, all you have to do is take your paperwork just make sure your insurance Co has sent your insurance info to the state because they won't accept an insurance card as proof, and sometimes it takes up to a couple of weeks before it's in the states system, if you bought it out of state in most counties here you have to have the VIN # read by Ga State Patrol...for a small fee...
