I bought a two brothers exhaust for my '07 cbr1k. and after looking at the instructions and some pics from other people i was woundering about putting the top black cover back on. then i seen this video from you tube.

What are the silver side pieces, and where can i get them?

Also we dont have very many cbr riders around here. can some one please show me a pic of how they have theirs set up?
