Sorry about posting useless info but I am too excited to do nothing!
I will be removing the rear cats and going dual all the way into a dual in/out Dynomax muffler with an X built in. I'll try to record some footage, that is of course, if I can find my camera. I am also in the midst of making a DIY intake. I would go with Needswings but I like things symmetrical, even if I get less power, and I want to keep the engine cover on.
