I'm happy with my setup, it drops weight, sounds good, and top end feels great on my setup. But, just wondering what you guys think. I believe it to be true.
TIA

You're right, two 2.5" pipes have a total area of 9.818" and a single 3.5" is 9.621". Very minor. The major benefit comes from removing two nearly 90* bends in the first half of the pipe and the secondary cats.
