Wow man as if you own the Pentroof Z. Thats insane. The minute i saw that amazing quad muffler exhaust and have been looking everywhere on the net to see if I can get one. But after reading your msg here about it being stripped off I was dissappointed. But good for you for trying to recreate it. It really looks like a cool setup. Lemme know how it turns out (if you do recreate it)!
