From the Driver SeatTRD's air intake has the typical OE overkill, combined with the aftermarket benefit of increased air flow. The Gibson exhaust we had installed on the Tundra was not compatible with the suspension drop kit. The tailpipe ran right into the leaf spring. Since this was a yet-to-be-released product, we gave Gibson the opportunity to either tweak the design with flip kits in mind or to come up with a one-off fix for our vehicle. They gave us the fix, and maybe the fix will show up in its kit. By the way, the power gains from the exhaust were 16 hp and 22 lb-ft-we didn't get any dyno time with the air intake-and the exhaust note definitely sounds aftermarket. We like the McGaughys drop kit, since it was relatively straightforward to install. In retrospect, we would have probably mounted the shackles in a 4-inch, rather than a 5-inch, drop configuration. The truck does ride well with the new suspension. We only experienced tire rubbing once when we hit a bump at a weird angle, with a load of wheels and tires in the bed. The D'Vinci wheels and Nitto Tire tires look like a good combination. We like the low profile and the tread pattern on the Nittos, and the fact that the inserts on the wheels can be painted does add another customization option.
