What did you do to your car today?

Modded my airbox to bypass the resonator. I was hoping for more induction noise, but I got a more bassy engine note instead which I’m digging. VTEC transition is also more pronounced. Not sure if that’s just due to the colder temps though.

Most likely due to whatever intake/exhaust modification you made. With an exhaust and intake, VTEC gets a noticeably more aggressive crossover.
