When you are talking bolt-on performance parts, an increase of 20 lb-ft of torque is pretty good. Not until you slap on a forced induction or a nitrous kit will you see gains above 30 out of one modification. Once in a while, all the planets align and something amazing happens, a modification blows our minds. That is exactly what happened when the guys from Tube Technologies Incorporated (TTI) swapped out the complete factory exhaust system on an '06 Dodge Ram with a 5.7L Hemi for a set of pipes they built. TTI has spent the last 19 years perfecting exhaust systems on Chrysler A-, B-, C-, and E-body musclecars and has now moved into the truck arena with this kit. Once TTI had its kit on the truck, the dyno showed the results: a gain of 42.9 lb-ft of torque!

What makes the TTI system different from some of the others out there is the length; TTI only makes the long-tube style for Ram pickups. In exhaust theory, the longer the exhaust pulses from each cylinder stay separate the better. Not only are the tubes much longer than the manifolds they are replacing, but they also feature a larger 1-3/4-inch diameter. A CNC mandrel machine is used to keep the inner diameter of the pipes even and consistent for a great fit and improved exhaust gas flow. Each set of headers is manufactured from 304 stainless and has laser-cut 3/8-inch flanges.

Since we are talking about a complete exhaust system, the headers are just one component in the recipe. The company also gives you a whole new Y-pipe setup, along with two high-flow cats to really let the exhaust flow freely. After all those gases escape the headers and Y-pipe, they flow into another length of 3-inch stainless pipes and TTI's high-flow muffler. This muffler features a straight-through spiral core design with fiberglass packing to quiet down the exhaust note to a healthy growl. From the muffler, the exhaust travels through another mandrel piece of stainless tubing that is capped off with a nice 3-1/2-inch stainless tip.

The whole system is made to bolt right into the truck, retain all the factory hangers, and requires no modifications to fit, so put the prybar away. To validate all of these claims, the truck was strapped to Westech Performance Group's chassis dyno and tested against the stock numbers taken earlier that day.

AND THE WINNER IS...
After fours rounds of intense head-to-head competition, the TTI system is a clear winner over a stock exhaust setup. When the install was complete, the truck was tested on Westech's in-ground chassis dyno, and the numbers speak for themselves. The truck got 42.9 lb-ft of torque shot in the arm at 3,400 rpm, and as we all know that is right where you need more power. Now when the truck downshifts during a passing situation, you really feel the power pulling you back in the seat.
