That looks great! I've been debating on fabbing up my own x pipe for quite a while now. In fact, I just PM'd Mike to see if he had ever thought about offering an x pipe as an alternative to those who don't want to go with a full system. With that being said, if I had an exhaust shop around here that could do clean work like what you've pictured, I would reconsider a custom system.
I'm anxiously awaiting a sound clip!
