nwb up/p ? flex or not and why

I see vishnu has bot flex and non flex up pipes, why. they also only claim 10whp on the non-flex unit, does this mean the flec causes more turbulance and less power???

this has been discussed at some length, and the consensus seems to be that flex pipes do not cause exhaust leaks (if properly installed), while non-flex pipes eventually will. personally, i bought a flex pipe. i'd rather loose a couple of horsepower than have to deal with an exhaust leak.
