I do think Mori's look better except they are too long. I love the Ti pipes & carbon shields--on Sato you have to choose
But the Satos are far easier to get & according to LDH, work better.
the moris ARE longer BUT, leave us to discuss exhaust smell lol
satos are tucked up under the tail but are pretty short, especially the Gen 1's, the Gen 2's are a bit better w/ the extended outlet that's a wee bit angled....whereas the Mori's are indeed longer, split out from the tail a bit (you can adjust how much) and they have the extended, downturned outlets which does make a difference
Big Valley Honda can get you all the Moriwaki stuff you need and the CF heat shields are dead sexy...
sound wise, the satos sound more raw, raspy at idle and just evil at WOT.
the mori's are a bit more reserved at idle letting out a low rumble but on the gas they begin to sing and the note evolves into this wail that is all it's own and all business
should you happen to mate the Mori's to a Fat Y and you'll hear your 919 breathe like never before and the front end won't stay down in 2nd gear
i did at one time, contemplate cuttin down the Mori's by an inch or two...no more. i've got it setup just how i like it
