    Hello all. I have a 99 VFR that I am wondering if I put a slip on pipe, not only would it sound better, would I get better fuel economy? Mine is a california model, and I am averaging appx 41 mpg riding on the freeway. I am doing a 50 mile round trip daily with 6 miles in city driving. My only mods are heated grips and a K&N air filter. Thanks in advance!!!

    Well, with a better sounding bike you may have the tendancy to run it a little harder just to hear the engine talk, which will cut your mpg a bit. Even if you manage to ride it conservitavely, I do not believe you will see an increase in mpg. I put a D & D on mine and I noticed a small drop, by about 1 or 2 mpg, but I was riding it harder. Then I went +2 on the back sprocket, and I saw it drop some more. I probably avg in the low 40's now.

    I've had two different pipes on my VFR, a TBR & a Scorpion.

    The TBR made no noticeable improvement to power or mileage.

    The Scorpion made a BARELY noticeable improvement to power & no noticeable increase in mileage.

    As with all slip on mufflers, you're going to get 2 things.
    1. Weight Reduction. The stock muffler from my VFR must weigh 20 pounds.
    2. Noise. VFR's sound awesome & letting it sing is a welcome benefit, at least it is to me.

    If you truely want to increase your mileage, look at you own riding style and look to see where you can shift up sooner & stay in higher gears longer. Pretty much the only thing you can do to really increase your mileage will be changing sprockets. Then you change the way the bike accelerates. How important is an increase in MPG to you? You can spend large $$$ and never see the results you're looking for.

    I think less. I have a CA model 98 with a 2bros and my mileage is usually 33-37mpg.

    I think if your bike was a Prius, it'd be getting 33-37mpg. Riding style has a HUGE effect... Plus the K&N and PC just scream, POUR MORE FUEL ON THE FIRE!!! ;)

    I get 45-47 on my vfr with just the slip-on while commuting. About 40 loaded for adventure or riding hard.

    I think KC pretty much nailed it, My 99 gets about the same MPG as yours if I take it easy, and I have a K&N filter, Staintunes and a Power Commander...
