Im waiting for Bazzaz to release their Fi unit and I will be getting that. Then I can control all 8 injectors instead of just the 4 primary like the PC does. The reason you could see them glow was due to the fact that it was pitch black out, they are Ti, and the fact that we were running the bikes pretty hard for an extended period of time. basically WOT. You could just tell they were hot. Not like I had neons or some shit under there. Riding like that causes the pipes to get a bit warm. If it was day time, you would have never noticed. I guarantee that anyone that goes for a ride like that will most likely notice the same thing to some extent. You should also note that like I said, I have Ti header(s) "is that better satan" Most bikes come with Stainless although more and more are coming with Ti. (aka all the GSXR1K now)There is a substantial difference in the way the materials heat up and dissipate heat. Also there is generally a difference in wall thickness between the 2.
