Our new deal is the




.It is a combo pack of the GRUNT and SNAP airbox insert for the highest velocity of air going into and out of your engine. Stronger response right off idle and better pulling power throughout the rpm range and even more on top and you save money when bought together.  You'll only get this sweet deal here and even great for a new 2014 stock EXC or XCF-W


Dave,  If you come across anyone that gives you any crap about the $160 bucks for the Big Bottom End kit please give them my email.

I just got back from my second ride.  My first ride was stock, no changes no add ons.  The second ride was after adding the Snap, the Grunt, and removing all the emissions gear from my new 2014 500 EXC.  All  can say is WOW.  I was skeptical to say the least.  I can testify that the products you designed and engineered really changed the way the bike performed. There is raw smooth power from top to bottom.  No popping no funny noises.  The bike is great to begin with, your products really make it fly.  

Thank you for all your help and I look forward to moving on to Phase 2 of your improvements for the big KTM.

Thank you…Bruce McCleave 

Just got back from my first ride after installing your BIg Bottom kit on my 2014 500exc and I gotta say I was smiling bigger. Riding in the tight woods of NC the extra pull on the bottom really helps and what a deal. Thanks for all the great info on your sight. Jeff

Hey, I just wanted to let you know that I am super happy with the big bottom kit for my 2013 ktm 500 exc, I have owned the bike since june and these upgrades were the best that I've done to the bike so far. They really improved the bottom end. I was surprised to see that the grunt exhaust manifold was actually smaller than the stock, i would've thought more flow would lead to more power but what do I know. Anyway, thanks a lot. Happy Holidays.



This is our reason for being …


You know everyone wants the perfect bikes for them. We do. And the only way to do it is to change things to your liking. This is basically going from point A to point B.

Point A is the stock bike we all have to start with. You first choose the best baseline bike (point A) that you think will fit your needs. Then, you decipher though all kinds of available information to help you change the bike into the perfect bike for you (point B).

And this is where we come in.  We get bikes off of the showroom floor, like you do, and then we figure out the best bang for the buck fixes to the most common areas of interest for these bikes.  All info we have provided you with has been designed and tested to do just that for you.

We try to provide you with things that will make your riding experience more enjoyable. Everything we put out there has had lots of feedback and testimonials and provided lots of smiles without wasting any hard earned money.

So watch some videos and read about your bike and hopefully we can help you smile bigger too. Thanks for the support!
