You have to make 10 posts before you can post in the classifieds. You have 3 now. Just post a couple of "Hi theres" to other riders, and your practically in. It would look better if you did it yourself than me posting for you.
Good luck in selling your exhaust. I'd be happy to sell you mine when you're ready.
The answer is probably no, unless you're looking for the OEM system. I have two used OEM systems, and a brand new TM still in the box. I assume you are referring to that. Is your AR GP3 still in the box? I also have a full sized Akro TI with SS headers I'm putting on the bike, so what I'm trying to do is sell the TM, not trade for it. If I'm wrong, let me know.
