Not really. And you, for one, SHOULD give a "rats ass", because you really *DID* replace the exhaust, and not just the muffler. There is a huge difference. One costs a lot of money and actually affects performance. The other just makes more noise and CHANGES the look (not necessarily improves it
).

Hmmm, seems that discription above fits one member very well.
Hey- I resemble that remark....

Lets go do a dyno between our bikes and findout, or maybe I will go do one just to prove you are not 100% accurate? There are good, better and best when it comes to slip ons and systems, and no not all are loud screaming race exhausts. The stock unit is in fact hideous, Kawasaki needs to do much better, lighter "and smaller" for a bike this nice.

I will watch this one from the sidelines.

With the ONLY change being the muffler? If there was more than a 0.5% difference in HP, I would be surprised. And tests would have to be on the SAME bike, because I estimate the difference (if any) to be below the range of statistical significance between bikes or even between dyno runs.QuoteThere are good, better and best when it comes to slip ons and systems, and no not all are loud screaming race exhausts.

Oh, I know not all are screaming, I am just being contrary. There is no question it is big; with the bags on I think it looks fine to me, and I will never have the bags off. Weight- well, it is not light, but overall I don't think it matters that much. For example, I weigh only 150 lbs myself, so my bike is already at least 25 pounds lighter than average riding condition (perhaps that is even too low an estimate) I know every bit adds up, but most of us are not on the track where 10 or 12 pounds might actually matter. I will take the 0.001 second penalty.
Now, if I could lose 10 pounds of fat on my stomach and sides (and keep it off)- THAT would be worth many times the price of a muffler!!!

Does anyone know why my fuel economy went down 4mpg since I installed the muffler?

Too much wristus twistus.

Changing the muffler should not affect MPG (in any statistically relevant way). It is far more likely you are having a heavier throttle hand lately.

I know... my wrist was directly connected to the new found sound coming from the bike. I imagine that will last for another tank or 2 and then I'll be back to normal.

Hopefully you are directing your comments to someone else. As you can see, above, I was the one that called myself pedantic and then followed up with which definition ("a person who overemphasizes rules or minor details. ") (And I do tend to get stuck on details, but in my line of work, that is important; and in technical communications it is vital).
I am very quick to admit when I don't know something or was wrong and don't believe I ever try to dazzle anyone. I am far more interested in group-think coming up with "truths" and good info to share. That is one reason I really love these forums; there are a lot of people with a lot of knowledge and viewpoints and when we pool it together, it seems there is no problem that can't be explained or solved. Sometimes there are disagreements, but it is always civil, and the dissent still ends up making a more informative and useful thread.

Above all else I value humor and smarta** remarks. Makes life worth living. Can't stand being serious...just ruins my day...

If you haven't guessed by now, I somehow always end up being the "straight man". Although generally far too serious, I value and can dish out humor with the best of them.... just takes a bit more effort
Oh, and when it does come, ya never see it coming....

There is a very good article in the December issue of Motorcyclist magazine regarding the Two Brothers slipon and the use of the Power Tips to reduce the sound. It also talks about how the tips affect the power on a ZX-14R.
There are interesting differences between the HP level with the unrestricted Two Brothers muffler and the P1X (most restrictive/quietest) Powertip and the P1 (least restrictive) Powertip. The HP was actually 1.3 bhp higher with the P1 tip over the non-tipped muffler.
Although they don't provide the HP gain by adding the slip-on, they do give the differences between un-restricted slip-on and the HP with the two different Powertips.
Unrestricted: baseline for tip comparison
P1 tip: +1.3 bhp, -2.7 dB @ 5,000 rpm (highway speed)
P1X tip: -2.7 bhp, -4.5 dB @ 5,000 rpm

Within a month I'm having my bike dynoed, with and with out the P1X restrictors , I also have a flashed ECU, ZX headers with cats removed . When we Installed the restrictors six 1/4 inch holes were drilled in each P1X but was loud so I filled all twelve 1/4 inch holes with red RTV, since the holes are there already I'll try a 1/8 inch drill while on the dyno to see the differance in HP and sound.
I don't want Max MAD with me . MAD MAX is one bad ass dude.
