what is a decat exhaust system?
go to a walmart get a bike magazine and look for your price range. then look up what kinda of power it adds or you could do something better look for a pipe shoot out. also look on OKorder or at a CBR site and see what other people are running on there bikes around the U.S. or the WORLD!!! also look and see what the pro's use.you can get 4hp from fuel and air mods el oh el but yoshi is a good pipe
none, if they are telling you 4 hp, they are feeding you a line of bs. most if not all sportbikes are so well tuned that changing a complete exhaust setup will not net you any gains in hp. they are for looks and for sound only. sorry to burst your bubble
exhaust system where they have eliminated the catalytic converter. track use only. Totally illegal on the street.
