Just installed the Borla S Type exhaust into the 2016 4Runner limited.
Few tips:
Instructions say 15mm socket - wrong. It’s 14mm.
The screws near the rear axle are IMPOSSIBLE to take off, I don’t know if it’s because of the rust or if they just welded it on the other side but it took a cutting torch to heat the screws enough to take off. (Didn’t want to ruin the factory exhaust but just cutting it off)
Take the heat shield off near the rear axle, super easy to snake out the tubing.
Overall it took 4 hours, a cutting torch, a ton of penetrating spray and WD40. Haven’t broken the exhaust in but already notice a nice growl coming from it and can feel a little bit of power. I have it paired with a K&N CAI so cant wait to see the results in a few months once it’s broken in.
