Description: THUNDER TORQUE INSERTS™Increases Low & Mid Range TorqueAdjustable Sound Volume & ToneFor Your Exhaust MADE in The USA!byDK Custom Products FEATURES & SPECS:High-Temp Powder Coat FinishStainless Steel Studs (5/16" diameter)Includes All HardwareIncreases Low & Mid Range TorqueIncreased Exhaust Gas VelocityIncreased Inertial ScavengingAdjustable Sound Volume & ToneE-Z Installation Bolts into the end of the slip-on muffler (using the baffle bolt hole)Patented TechnologyMade in The USA! Do you want Louder Exhaust? Quieter Exhaust? A Deeper Tone? A More Aggressive Bark? Do you want More Torque? 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 maximum 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. If you feel that your current exhaust is too loud, the Thunder Torque Inserts™ will noticeably reduce the decibel levels. The comparison may seem subtle but decibel measurements are not linear.For Example, 90 decibels is four times as loud as 70 decibels and 110 decibels is about 16 times as loud.These particular results belong to a customer that had this to say..."My impression of the sound is that it lost some higher pitched bark at roll-on and there was a reduction in low pitch reversion "echo" (kind of a flabby chuffing sound). To my ear, with these pipes, the tone isn't significantly lower but it is a bit cleaner or more refined sounding"(Twin Cam at Full operating temp, mixture corrected, and idling at 1000 RPM.) A small change can make a BIG Difference!!!THE MOST TORQUE & HORSEPOWER GAIN PER DOLLAR SPENT!!!YOU CAN'T DO BETTERCheck out the Dyno Charts Above! "Just wanted to give you a heads up. I received my Thunder Torque inserts (W118)a couple of days ago, put them in and finally was able to ride today. Great product.It toned down the idle and low rpms on my Vance and Hines Shortshots. The increase in the mid range is awesome. I was expecting to buy new pipes, but not now. The Shortshots have become a performance pipe with great sound." -John "I do not usually thank people, but I just got the W118 installed...so much better pulling out...Big Improvement...Anyway thanks, another satisfied customer. Bike is a 2012 FLHTK with Stage IV Harley kit, dresser duals and street cannons. It did change the exhaust note as well, a bit crisper is the only way I can explain, that's also a win in my book! -Eric "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
