The Husqvarna's are out and the questions are coming in.

Even though the pages and vids are being made, the short answer to the short question is,  Yes, all the stuff that fits the KTM's, work on and fit the equivalent Husky model.  The only exception, is that the SNAP, and therefore the Big Bottom kit, does not fit the 450 or 501.  And using the TPS tuner is the only way, right now, to get your FE-S model running richer and better.  The ECU cannot be re-programmed on these models.  KTM maps won't work in Husky's.  You can read through the KTM pages for now and get the products from the Husqvarna products to purchase pages.

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, black or blue

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.  It's the only end cap designed to not burn the stock turn signals.

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 for both of them, it's half of what just an aftermarket slip on is.

Dig this blue one we made for the Husky guys. also looks cool on the KTM's.

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.

If you have the EURO MAP in your bike already, you really shouldn't need to use the tuner, as it may make it to rich.  You are welcome to try it though, as some have loved a higher tps number with the euro maps.













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.
