basically get a red bull can, they come in 3 sizes these days so it will probs fit your standard exhaust,
finish it,
get some scissors and cut the bottom off just where the label ends or just cut from the middle out so its like triangles,
fold them into the can,
now cut the top inside the silver ring, and just break those bits out.
slide it onto your exhaust,
volla a red bull exhaust tip,
)you could also do this with your standard coke cans or rockstar cans)
hahahaha
Basically i was sick of my dirty vl's dirty exhaust sticking out the back
