Richie, what kind of info, besides pics, are you looking for concerning the Two Brothers Racing 4-2-1 Exhaust system. I've got good news for you if your looking to losse 19 lbs, and gain about 14 HP. Mine ran 169HP with out any airbox or fuel map changes. It got a little better with airbox mod, but it's a little lean now. Still though, for the money, you can't, and won't beat the Two Brothers quality, fit, and finish! Nevermind the affordible price! Good luck.
