Re: Thinking of buying the TRD cat back and air filter
Like all after market accessories, there is a lot of argument about just how much power this exhaust kit adds. Generally speaking, after market exhausts by themselves offer little in the way of additional power. Typically, the most you’ll see is a 3-5 hp gain with just about any cat-back system. The TRD kit is no exception — our tests show that the TRD Dual Exhaust for the new Tundra added anywhere from 1 to 5 hp. Unfortunately, the increase in horsepower varied quite a bit depending upon RPM. That’s why we like that “3-5hp” number. Check out the dyno performance graph below.
Oh, I wouldn't go betting the farm on that.
