I am thinking about the xcan as well. Not that the tuned pipe doesn't deliver, I just don't like the look. I am also afraid of doing damage to it. I have never seen or read about anyone doing any real bad damage to it, it's just me. If I get into racing, than I would probably go that route.

I just ripped all the stuffing out of my stock muffler the other day. Not exactly easy, but I do have increased power. Not that much, but I do feel the differance. Not to mention the engine sounds great, has that nice crisp sound to it.
