You should leave it. Even if your state doesn't visually inspect it, you might have to let the insurance company now so they can raise your premium for 1 less airbag...

If you really want to change the style, then you should get a steering wheel that has an airbag as well.

It seems like you don't want to spend much money on the mod. If so, just don't do it. It's not worth it if you're just going to skimp out on it.

Otherwise, maybe see if you can get the steering wheel off another accord, like the TSX ;-P
