i know those are far better pipes but how many Db's they put out?.....what about a WB E-series?

 

The Big gun isnt that bad im not sure the exact DB's nut it is a nice pipe and ive never heard a yoshimura but know it is really nice. i have heard a WB Pro meg and it is louder then the Big gun race series.....
Hope this helped.

 

the big gun for the 250ex is louder than the Wb e-series fot the 250ex. they dont make the pro meg for the 250ex.

 

hey just wanted to let you know i put the big gun on mine and i could feel the diff. in the bike...but then i saw the yoshi and got that....it is made so much better and is bigger then the big gun..its stainless steel and you could put the heat shield on ....i have yet to get it installed but ill let you know how the bike is with it.....i think it will be even better
