unless you guys plan on runnin a blower, you dont need a 255 pump. And if you do get a blower, you shouldnt worry about any noise whatsoever because hopefully you will have a catless midpipe and you wont hear the pump. with that being said, just get the 190 fuel pump and be done with it. i cannot stress how easy it is to change out a fuel pump if you do get heavier mods at a later date. hell its only two easy bolts to drop the tank. so just get the 19o pump and be done wit it
