What mufflers should I get?

Heartthrob makes a decent turbo muffler that sounds good, at least in my opinion. Some others might have different opinions. I own an exhaust shop and have installed a lot of them on people's classic cars and don't get any complaints. I would definitely get rid of the 2" and run 2.25" at minimum or 3". 2" is too restricted and creates too much back pressure. An engine can only suck in as much air as it can push out the exhaust. Again, just my opinion.
