From the Driver SeatThis truck was only a week off of the lot when we began with the intake and exhaust, so we couldn't get baseline numbers for fuel economy, but the intake and exhaust definitely had an audible impact on the engine. The True Flow intake kept a low profile under the hood, but judging by the sound alone, flow has increased. On the exhaust side, the addition of both a Flowmaster resonator and 50-series muffler keep the engine hushed at cruise rpms, but opens up to a mellow rumble above 3,500 rpm. Throttle response was improved and power was definitely up, but without a dyno for this install, we can't really speculate on just how much power was made. The RCD kit went on smoothly, although all Toyota kits are inherently labor-intensive due to the ball-joint placement and hub construction. The owner loves the ride and handling, the only real complaint from the driver is that powered steps aren't available for the Tundra, as step-in height just jumped up over 7 inches.
