    Hi, I just bought a new 2018 4runner, 4.0v6, and would like to know if anyone has replaced exhaust, or muffler and increased the power and or gas mileage. is less back pressure a good thing to do on these? I know some v6 engines it will have the reverse effect.

    Today, I purchased the AFE Intake, Throttle Body Spacer, and Exhaust (20% off through AFE web). Suggested +36HP total. Intake is on back order until next week. Will post pics and thoughts once installed.

    These trucks are not race cars, they are meant to be a serious off road truck. If you really want power there is a super charger if you want to shell out 6k. Other wise preformance mods other than that dont really provide much to these trucks.
