I'm a metal fabricator/welder by trade and I'm used to being able to make my own parts. Occasionally I make parts for friends (sissy bars, license plate brackets and such) and I take great pride in my work. I haven't really found anything I wanted to make for my street glide other than exhaust.
My question is this - If I make a short 2 into 1, kinda like Sinister's "up yours" exhaust, what kind of baffle should I use to get the back pressure needed so I don't loose my bottom end? I thought about getting a stock head pipe and start from there. Similar to these. Any help is appreciated

I would look at all the 2 into 1 baffles and use one of those, Vance & Hines has 3 different baffles for their 2 into 1 pro pipe, quiet, standard, and competition, there are lots out there you could try, I like the Up Yours exhaust and the Covington Destroyer.

Call Bubs and ask them.... They make a **** ton of pipes (including rineharts and others) and sell baffles separate off the shelf.
I'm sure once you get past a receptionist with the correct question you will get the info you need.

Also take a look at the SuperTrapp website.
Their mufflers (slip-ons) work by means of a series of disks that stack inside the muffler cylinder. You adjust the HP, torque & loudness by the number of disks you install.
Simple and effective.

What about torque cones and torque chambers? I don't have any experience with these. Do they give the needed back pressure? Seems like the don't need as much space. I like loud pipes but don't want it to sound like crap either

Exhaust design is a combination of engineering and various black arts. There's a lot more to it than just bending and welding tubing. Companies spend a pile on R&D to get a pipe right.
Unless you've got a ton of time on your hands, and the equipment necessary to test the results of your experiment, I'd suggest against trying to fab your own.
I mean absolutely no disrespect to you or your abilities.

I know that R&D is a big part of an exhaust manufacturers program. However, a lot of guys out there run straight pipes and are happy with them. How much R&D went into those? I think I can do better than that so what's the harm in trying? I just want to build something different

Khromewerks makes a good universal baffle. Big City Thunder has a quiet baffle too.
Here's a couple articles to get you started:
