Sounds like a Mazda rotary. That's about my only complaint. Exhaust piping looked to be 2.75" to me so an aftermarket exhaust would yield more power and better responce yet and sound better. I really love the muffler the factory went with tho it needs to be a little more matcho in normal mode and straight loud when the valve is open.
I wanted to share some 360 videos at an HPDE mostly because I think the tech is really neat and I think it turned out pretty nice. You can use your phone to move around the video or if you have a VR headset, that works too!
Be sure to set the quality manually to 4k in YouTube...
