RE: Power Decrease Using Exhaust Deflector.
Mr. Bagle,
I also used a deflector on my MVVS 1.60 glow, with the MVVS #3266 tuned pipe.
It pulls like an ox! I cannot tell you the exact RPM difference, if there is any, but the deflector is the same i/d as the pipe's stinger, so it essentially both extends it and bends it...
It is the .35-.90 size extension, but it does not seem to choke the engine down, like it did on the MVVS .49.
