Not to hijack but, I love the RPi so much, honestly I think I love it the most out of anything else I've done to the car, I had so many doubts and concerns before I bought it about the drone and the sheer volume that everyone was talking about, and now about 4 years later I still can't get sick of it, even after going with catless headers this year it just made it come alive even more. All the pops and burbles when you lift off just make me so happy inside
This is what mine sounded like in action before headers. Start it at 20 seconds to skip the boredom.
And here it is on-track after going with Fabspeed catless headers.
