Proudly tuned in Sycamore, Kansas.

For the best results with pop tunes, we highly recommend removing your PAIR Valve or emissions system.

Without it, your bike may struggle to produce consistent or aggressive pops.

Check out our Universal Pair Valve Delete Kit in the Add-Ons section—it's affordable, easy to install, and makes a big difference!

Free Shipping is included with all U.S. ECU orders—except California.

California Orders require a $30 compliance handling & shipping fee due to state-specific regulations.

Return Shipping speed is optional at checkout.

Expedite handling can be found in our add-ons section. This is where you can find the Same Day Turnaround option.
