Watch these videos on how to get a better sound AND increase torque!

Take a listen to the following sound clips of 5 Different Bikes that all have an increased amount of Power from Thunder Torque Inserts™ Being Installed.

 Another Video showing how good the stock exhaust can sound, and how much power they can have, with the baffles removed and replaced by Thunder Torque Inserts™.

 

Without getting too technical, we've spent thousands of hours testing shape, size, thickness, & surface coatings to find the optimum combination that increases power across a wide RPM band, AND gives maximun flexibility to deliver different sounds.

The Increase in Torque is accomplished by reducing engine pumping losses, increasing exhaust gas velocity and increasing inertial scavenging.

Thunder Torque Inserts™ are designed to perform well when used on slip-ons with and without baffles, drag pipes, shortys &   2 into 1 Systems. 

The Patented design  will produce a bit deeper sound/rumble all the way through the RPM and Throttle range.

"We just installed the Thunder Torque Inserts. The change is very noticeable.   ..using Screaming Eagle II Slipons without baffles.   Metallic sound disappeared with the inserts!

...always a drop in power from 2,700 to 3,200 RPMS in any gear.   Now the power delivery is very linear and smooth in the whole powerband.

 

It's amazing to feel that something so small, simple and easy to install made so much difference on the bike !!

 

Thanks so much for all!!!" -Concha

 

 

"Just wanted to take a minute and let you guys know how pleased I am with the W258 TTIs.

 

I'll be honest, when I first read about these things I figured it was somewhat gimicky so I didn't expect much. But, after removing the baffles from my Wild Pig slip ons and installing the W258's I was blown away by both sound and performance!
