Titan 3-inch Exhaust
| Start by removing the two bolts from the flange that connects the muffler and the tailpipe.
One of the first things that people do when they pull their new truck off the lot is gloat to their friends. After that, they usually grab one or two of the easiest performance upgrades on the market, such as an intake or an exhaust. These basic upgrades unlock horsepower that are just waiting to be released as your ride rolls off the production line. It shouldn't be that much of a surprise that we wanted to do the same thing with our Nissan Titan project truck.
Originally, we had planned on doing headers and a full after-cat system, but when the Nissan engineers designed the exhaust system on the Titan, they decided that the best placement for the cat was literally right on the exhaust manifold. The design makes it a little difficult for manufacturers such as Gibson to create smog-legal headers without altering the position of the cat. Hopefully, in the future, we'll see a header solution that will still get past the smog nazis, but until then, we'll just rock out with our Gibson pipe.
The Gibson after-cat single exhaust is the epitome of easy performance, unlocking 12 hp and 13 lb-ft from the 5.6L powerplant as well as a few mpg, all in less than an hour. Follow along as Shawn helps us swap out our factory pipes for Gibson's 3-inch heavy-duty stainless-steel exhaust.
