Next up: a 2022 WRX GT proving the CVT can still have some fun. 👀

We know the CVT cars catch a lot of smack talk, but this one showed up and put down 282.99whp / 304.18tq on 93 with DMann Tuning — and that’s with the shop still absolutely cooking in this heat.

Mods:
Extreme Turbo Systems Intake

Not bad for “just a CVT.” with just an intake 😏
