I knew you'd say that, Nick. Sorry about that... I really don't think that the Fabspeed tips are a good option either since they turn "brown" from the heat emitted from the exhaust. That's what happened to my cargraphic tips originally and I ended up having them ceramic coated black to hide the "brown" stuff. Didn't look very pretty.

And Nick is right, the exhaust gas does come out of all four tips.
