Fantastic Four Buildup - '07 Toyota Tundra

There you have it, TRD's new intake for the '07 Tundra 4.7L V-8. TRD claims that the assembly achieves an increase of 27-percent in airflow, all while still filtering just as well as the factory assembly. And more air means more power. Also, the TRD setup retains the California Air Resources Board's required hydrocarbon filter that appears in the factory filter system, so the TRD intake still captures polluting vapors that may escape when the vehicle is parked.

Gibson Performance installed their kit at their facility. Here, the new Gibson exhaust lies next to the factory exhaust we had taken off of the Tundra.

The first two sections of pipe, the inlets, were bolted loosely to the flanges. The stock rings were used and hung in rubber grommets that had been sprayed with WD-40 beforehand. All of the rubber grommets were lubricated the same way.

The muffler was lifted into place and the inlets were slid into the muffler. The inlets and muffler had to be leveled to achieve the right fit, so a carpenter's level kept everything straight and the connections were tack-welded to keep them secure until the rest of the exhaust system was in place and the welding had been completed.

The next section of pipe was slid onto the muffler and hung in a lubricated rubber grommet.

The tailpipe was slid into place and hung in a lubricated rubber grommet.

Here, the chrome tip was bolted onto the tailpipe.

Once the chrome tip was adjusted to stick out just so, then the pipes connecting to the flanges were bolted tightly and all of the other pipes were welded together. By the way, the kit can be bolted instead of welded, but Gibson prefers to weld them. Abrasive pads were used afterward to clean up the welded joints. And then we were finished

Here is the McGaughys drop: a pair of coils and a flip kit, plus rear shocks. We went to GO EZ Customs, a custom shop in Placentia, California, to have it installed. We figured that since this was a brand-new kit-as in kit number 001 that had been hastily sent to us by McGaughys, and hence had no instructions or anything-that we should take it to some pros to get the job done right. Luckily, this drop involved a relatively simple set of new coils and a flip kit.

Starting with the front suspension, the coilover assembly was unbolted.
