So Steve in your experience is there an aftermarket slip on which does not create a loss of power due to scavenging cylinder pressure?,or only minimal loss?
You're confusing terms. A slip on is not really an exhaust, it's just a muffler change,
and has little to do with tuning.
I'm talking about full exhaust changes, from the head back. Larger pipe diameter (the areaP is 9mm larger) no cats, changes to sequential / non sequential firing, 4 into one, tri-y crossovers, etc...etc these things make substantial changes in tuning needs. Steve
Yep, I keep telling people that. A "slip-on" is just a "muffler" or "silencer" with a short lead in pipe pre-attached. It is not an "exhaust". New "exhaust" means "exhaust system", which means replacing the header(s), the entire midpipe, and the muffler...... from out the engine block to out the tailpipe.
Come on now, "exhaust" is the stuff that comes out of the tail end of the muffler.
So a slip on wont effect performance through the throttle range? Does not create hesitations at slower speed/throttle openings.No Minor hp power and torque increase across the throttle range? No change in fuel/air ratio mixture at the output end of the exhaust on a dyno?
Only less weight,more noise and more appealing to the eye?
BUT, it sounds faster!

Yep. The stock Concours 1400 muffler might be big and heavy (and some think ugly, I do not), but it is not a higher source of restriction compared to the rest of the exhaust system. Replacing just the muffler without replacing the headers and midpipe has almost no effect on power or tuning.
I was toying with the idea to fit a Scorpion Performance Bike Exhaust Slip On Can Carbon Serket 7- slip on,and an ECU flash,but for an outlay of approx AUS$1400.00,{slip on $700.00 + Steve's flash to Australia after customs screw you over AUS$700.00 the standard quiet fugly exhaust is looking better every day. As far as performance goes the GTR1400 has more than enough for the Old fella and with eco mode excellent performance/economy situation.
Ok,so thats cleared up the situation with a full exhaust.So a slip on wont effect performance through the throttle range? Does not create hesitations at slower speed/throttle openings.No Minor hp power and torque increase across the throttle range? No change in fuel/air ratio mixture at the output end of the exhaust on a dyno?

Good, succinct write up. My results almost exactly. I think your mileage will stay the same. Mine went up consistently by 14-15% and I was in the 38-39 mpg range, too. Only problem with noticing the improvement is that you will adjust to it quickly and forget how it used to be, if your experience is like mine.
Wondering about backfiring. A full AreaP with Steve's AreaP flash, does it have a lot of decel backfiring? Will I need to do a pair valve ectomy?
Steve, have you actually tried your flash on a bike with the flies removed to see how it works?
