We are shut now until Dec 28th. Gonna ride and have fun and do my hair. Hope you have a great Christmas

Above is some dyno proof that the PQP end cap works.  The top set of lines ( purple and pink) are the torque readings. Pretty good and you can see the very top line is the torque of just the Big power kit ( big throttle body) and the PQP end cap.  The pink line below that is the stock xcfw end cap.

The green and brow lines below that, are the HP numbers.  So 60 ft. lbs of torque and 60 hp is pretty stinkin good. And yes I know the RPM's are off. For some reason, it only picked up the speed.

Dyno runs are taken at wide open throttle only. The bigger gains are at the lower throttle openings. And it's still quiet. This just shows it's not marketing hype and the kind of power you can get for $1200.  Just wait till we add the headpipe.

                  

A new, 30 day money back guarantee on the PQP end caps, the Grunt exhaust manifold and even the new headers that will be here shortly.  So buy and try with confidence.                 NO other exhaust place gives you this.               And the reason that this is done, is so

       You don't have to wonder and worry about if it's going to give you the power you desire and the sound level you desire.

       Just try the end cap, and/or Grunt, and see, risk free, if they are right for you.  There aren't any returns on the TPS tuner.

Well everyone, there are some pretty cool changes coming our way for 2015. A lot of it has to do with the new muffler end caps, available now, and then the new headpipes that will come later.  They are all from a place called "Power Quiet Pipes".  A friend of mine named Tom ended up retiring and with nothing to do kept working on his ktm pipes and ended up coming up with this cool stuff.  Since I always said that BestDualSportBikes would only sell what was the best, we now only sell their stuff.

Available in silver or black

How cool is this new end cap for the stock muffler, above. It changes the game for the EXC and XCFW guys, to make great power with minimal sound and minimal cost.  It's about time.  Look how cool it looks on the bike, here

Then install the GRUNT exhaust manifold for the best performing exhaust system you can get with keeping the tough stock headpipe and muffler.  For $260, it's half of what just an aftermarket slip on is.

Then you just need our TPS tuner here to the right, so you can accurately increase the output voltage of your throttle position sensor (tps) by being able to put exactly 5.00 volts into it. You don't need any different ecu programs or piggyback tuners. Keep your stock EXC or XCF-W program and increase power and response to your liking by cranking up the tps. Go to the TPS tuning page under "the products" to learn more.

Because of the tps clip, it does not fit the sxf or xcf models.  The "F" stands for four stoke by the way. If your bike is a 2011 - 2015 four stroke and says EXC or XC-W on the fender, this will work. If your bike is a 2011-12 350 or 450 sx , xc, xc -w or exc four stroke, this will fit and work for you also.

 

 

 

 

 

 

 

 

 

 

 

 

Let's watch it all work together now.  Watch the videos below to see how just the $260 end cap and grunt and $90 tuner transform the 500 EXC and XCF-W into a third gear wheelie machine.

 

First the 500 EXC in stock form

 

 

 

 

 

 

Now the 500 XCF-W

 

 

 

 

 

 

 

And now the kit and tuner, with using the stock 500 ECU map.  Notice the 2nd gear wheelies are instant now and it's now doing third gear wheelies. Still quiet, spark arrested, has turn down to not burn EXC turn signals and only $350 total

You can read more about it and see installation instruction vids on your bikes page.

All the parts are available separately and fit 2011-15 350,450 and 500 EXC's and XCF-W's

 

 

 

Next on the list for easy bolt on power is the Big Bottom Kit, shown on the left.  It is a kit, consisting of the Grunt exhaust manifold and the Snap air box insert, which slides inside the air boot.  Each item by itself is $100 but the is kit gives you a $50 savings.  Expect more "get and go" at all throttle openings and a much stronger throttle response down low. Installs in 10 minutes and there is no re programming (re jetting) required.  Find under your specific bike.

For only $149.95 it's definitely one of our best reviewed items.

The "Dead End" anti- vibration inserts, shown above,  were reviewed in the 2014 October issue of Dirt Bike magazine and this is what they said. " Through the mystery of harmonic frequencies distribution, the dead ends are pure magic. We bolted our set to a KTM 300 and could tell the difference the second the motor snapped to life. The higher the rpm climbed, the better the dead ends seemed to work"

On another note, the ones they tested have long been replaced by better ones, which don't make for slippery ends and can easily be used with wrap around hand guards.  Buy as a kit (below) or separate. Go to the dead ends page under "The Products" for more pics and info

 

The "Big Oily" clutch covers are a hit. Holding 25% more oil and made of billet, so you can't put a hole through it with a rock, it's extra protection and insurance for that $13,000 bike.
