I've been driving around and loving the new exhaust! I also threw in a voltage booster for my AGM battery...you just throw it into the ALT-S fuse and it tricks the alternator to produce more voltage to keep the AGM charging requirements in check...sporting a reliable 14.9volts while first starting and driving for about 30 min and it goes down a couple tenths as it's "topped-off" by than. All good things! Here's the voltage booster I used: Mini Fuse AGM Battery Voltage Booster For Toyota 4Runner, FJ Cruiser, & Tacoma | eBay
One can also use a Ford/GM diode - as long as it's placed in the right direction...you'll know if you have it backwards as you will likely have a battery light on the dash...
I just knocked out the infamous throttle body coolant bypass in the runner's 2uz...pretty easy but the lines were hugging the nipples something fierce...it'll be nice reducing the temperatures on the intake manifold without the 200°F coolant running through it.
