It will happen, There's no way to stop it.
Shit, I was driving an extended cab f-150 the other day and 3-4 people merged on me, No signal light or anything.
Funny part about being in a truck though is when they think they're coming over and you just look them dead in the eye and give them that "Do it, I fucking dare you" look. :lol:
I'm all for exhaust though
Just please get Akrapovic or Arrow, There is no better sounding or looking pipes for gsxr's than those 2.
