Better sound AND increase torque!​

Here is a sound clip of five different bikes that all have an increased amount of power from the Thunder Torque Inserts being installed.

Do you want Louder Exhaust? Quieter Exhaust? A Deeper Tone? A More Aggressive Bark? Do you want More Torque?

I put on true duels on my 11T/G [cat less] Then I added rush 1.75 slip-ons, Lost bottom end, and gained too much noise... So I gave the thunder torques a try..
[258's] Ten minute job.. Got the bottom end back and got rid of the noise..
Couldn't of been easier ThumbUp

...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. - Concha

Thank you for the kind words! I've had many people come up to me at bike nights and ask why my pipes sound so deep compared to their pipes. The Thunder Torque Inserts work incredibly well. They fatten up the lows and mid range and give such a smooth throttle response, and the tone of the pipes... well... :clapping:

A new customer review that came in yesterday!

"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.. About as close as you can get with a TC motor anyway. 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!"

Custom Review:

Review by Johnny Bravo

"I have a RGU w/ 4" slash cut Vance & Hines performance slip-ons. I removed the baffles to increase the sound and my safety. I lost torque and the sound was super loud. My buddy recommended the Torque Inserts and what an amazing difference in low and mid torque!!! I tried 3 different angles for the sound and decided to leave the inserts flat against the diameter of the pipes. Strong Sound! Deep and throaty."

Installed TTI tonight - engine light came on

2021 Freewheeler. We pulled the baffles out of the stock mufflers and installed the W258 Thunder Torque Inserts. We left the packing in the pipes.

1. The engine light came on during the first ride. I'd be interested in anyone's thoughts on this as I wouldn't have thought that pulling the baffles would have changed the air/fuel ratio drastically enough to cause the engine light to come on.

2. And, the inserts are not centered in the mufflers. Is this a problem?

TIA
