the 900 will give the best hp gain, slp claims to get close to 180 with some port work, heads v force reads and pipes. thats huge in todays sled line up. from what people say i think the zr 900 actually has a more forgiving or easier riding chassis,

I don't know if there is a good answer for that question yet. I know it took months for anyone to improve on the stock '03 900 1M pipe. Might have to wait for these aftermarket guys to figure something out.

I find that that it gets really confusing to buy aftermarket goodies for your sled but on my 900 I put d&d twin pipes and they work awsome. people tell me speedworks are faster but sound way to loud and in canada we already get harassed for twin pipes. but d&d are a great fit and no complaints at all.
