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.

 

***The Video Below shows how to Remove Baffles from stock OEM Mufflers that do NOT have a Catalytic Converter in them.  This process does NOT work on Mufflers that have Catalytic Converters in them.***

 

Do you want Louder Exhaust? 

Quieter Exhaust? 

A Deeper Tone? 

A More Aggressive Bark? 

Do you want More Torque?

 

The Video Below shows how to Remove Baffles from stock OEM Mufflers that DO have a Catalytic Converter in them. 

 

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™.

 

All the Vance & Hines Systems and Slip-ons we've tested produce more power, and a bit deeper tone with TTI's Installed.  The V&H's respond particularly well to TTI's, with or without the baffles!


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 and 2-1 Systems.

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

FITMENT NOTES:
 
When ordering you have an option of getting just ONE TTI if you have a 2-1 exhaust system that has only One slip-on, or to choose TWO TTI's for exhausts that have Two Slip-ons.
 
The "Q" model is no longer being manufactured.

A small change can make a BIG Difference!!!

 

THE MOST TORQUE & HORSEPOWER GAIN PER DOLLAR SPENT!!!

 

"Amazing how much more power these gave my 103 down low.  The sound is raw power too." -Phil

 

 

"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!

 It has the potato potato sound at idle (noticeably louder than before) and also sounds great at cruising RPMs. It actually reminds me of the way my old shovel head sounded.

 What really surprised me though was the very nice torque gain that you can really feel. After installing true duels and the wild pigs, I noticed a loss in torque. The TTIs brought all of that back, and maybe then some!

 Best money I've spent on my exhaust system for sure. Thanks!" -Dewayne

Thunder torque inserts Review by Doug
Ordered a set of the 258 inserts expected delivery in 4-5 days recived them in 2 days install was easy enough. The sound is a really nice rumble, torque increase for the buck is fantastic.
Bang for the buck best thing I've every found! (Posted on 11/8/2017)
