Exhaust......well Akrapovic was the best for the 98' and later ZX9's, but LP stop importing them into the country and so u are screwed. U can do my mod where you make the 2000 header fit the 98-99 head with a die grinder. The 00 on up u can just get the slip on. Muzzy's aren't bad either
Fairings? well I just like the originals, but huggers and undertails, just search Ebay
Rearsets... I like Sato, Gilles (look for EMA, only importer) and Woodcraft (see case covers)
Stands....there isn't any other than Pitbull IMO and u can find them cheap
Steering dampers.....I like the Hyperpro because it has Hi and Low speed damping that noone else seems to offer (but it mounts in a crappy way), but Scott's and Ohlins can be had in the 916 style as they are originally known. (for newbies, that is the current setup on the 2006 ZX-10)
Suspension....well now you are talking....2 choices only....Ohlins and Penske. Noone really runs anything else that I know of or suggests anything else. Ohlins are usually too expensive and the Penske's are real nice if you can find one for our bikes, I just got one off Ebay for $600 brand new.
Well that brings up the rear.....for the front have them revalved for hi and low speed and get a 1.0 spring that is good for a 190lb-260lb rider.
Turnsignals...Gregg's custom on Ebay
Wheels....Hi Point now called Carrozzeria, Marchesini, PVM ........all of them should be forged aluminum.
Windscreens.....ZG aka Zero Gravity...PowerBronze if you can find them
