couple quesions re rear sprocket and coffman shorty exhaust

[Once a Warrior]

1. anyone tried the supersprox rear sprocket? how do you like it?
2. getting ready to install coffman shorty exhausts on my '00. am i going to need to get a power commander and have it remapped and dynoed?

the super sprox are very nice but spendy. Pashnit has the best deals on the board for them . You shouldn't need a PC and mapping unless you are doing a full exhaust

Never ran supersprox but haven't heard anything but positive comments. Tune no.

ended up installing the supersprox kit [chain, -1 front, +3 rear]. ended up cutting my yoshis instead of paying the bucks for the coffman shorties. this really woke up my bike, impressive gains in acceleration and it sounds sweet. good bang for the buck if anyone is thinking of changing gearing from stock IMHO.
