Re: dual exhaust

Well I have a ported stock header, and the Yoshimura RS-5 slip on, with a hard style K&N and the Rais air tube on my Rhino 660.  And at 6000 ft altitude I run a 155 main jet if that is any help.  It seems to run good, with no hesitation or bogging, and it doesn't backfire at all on decel.  I like the RS-5 because I got it for just $281, it looks trick as anything, and it is just barely louder than stock, with a nice deep tone.  I've used my Radio Shack sound meter on it, and although I was guessing at what was "1/2 max RPM", which is where sound test are supposed to be done, I got 94 dB on the meter.  Thats pretty decent if you ask me.
