I almost went with V&H's 2 into 1 - but decided to do the Dresser Duals with Khrome Werks mufflers. I didn't want to mess with the Rineharts fit problems (07 SERK).
What are some of the reasons you like the 2 into 2 over the 2 into 1?
I like the looks of the 2 into 2 better and it helps to reduce the heat that I use to get from the right side of my bike with the stock system.
I know the 2 into 1 performs better - but I just don't like the look (sorry to those that have them!)
3 main reasons:
The heat issue you referred to already - right/left side is even with 2/2.
The ability to tune each cylinder independently of the other.
The "look" - 2/2 gives the bike a balanced look and the $&*$@#$

crossover pipe is eliminated.
There is a 4th reason on the Rineharts. I had one of the very first sets of true duals they offered and had several issues - bracket broke, ate a hole in the left header with the Kuryakyn passenger adjustable peg mount, and the first set of baffles were incorrect length (stock baffles) and they chewed a little hole in the bottom of each muffler. In each and every case, Bub (Rinehart manufacturer) sent repalcement parts at no charge - also free shipping. In one instance they overnighted since we had a trip planned and they made SURE the new headers were there so I would not miss it. After all these issues, they have given me no trouble. That is what I get for getting the first versions of new products, but sometimes I just refuse to remember why.

The performance they gave my 02 RK was well worth all of it.
