Sell the Honda and buy a Ferrari.

You will see virtually zero HP gain unless you change all the other aspects
of your engine, such as:
1) Camshafts
2) EFI map
3) Ignition curve
And then you have to still conform to your local emissions regulations...

Horsepower is not something that magically appears out of the blue when you
add a low restriction exhaust to a vehicle that might not have been
strangled to begin with. Has it occurred to you that you might get LESS
horsepower if you muck things up?

Do some Googling before you waste your money and become a Rice Boy.
