If you want a decent pipe go to www.powroll.com . My dad and I are the ones who made the Powroll CRF203F. All out of Powroll parts. The Powroll exhaust is a IDS2(Internal Disc System) and is a 1 1/4" all the way back. As everyone elses is 1" all the way back except bbr which changes to 1 1/4" at the canister. The whole point of the disc system is you can add disc and it makes more low end but makes the bike louder or you can take away disc and it makes more top end and makes it quiter. It is the same price as BBR and the others but is way better than the rest. Also looks better. This pipe made a big difference along with the rest of the mods but makes it easy when at the track and you need to change cause its a tight track or a wide open track.
