the manifold. basically from where its visible from outside the fairing underneath right up to the muffler, then the muffler tip. Im thinking its all just steel, and I would need to go to and ehaust shop and have it redone in titanium.
I think this would look amazing on the blue/white gsxf

But I did come across this site, and sent them a message to see if whatever they do will stand up to the heat... If it does I would like to send them everything, muffler and all.
