If your like me and not sure if this is worth it for the mc22... we'll, I'm not sure
Acceleration seems more stable, smooth, effortless.
Installation isn't that's hard, this stystem is pretty much plug and play, once it's wired in, you have 2 switches to play with, one is the rpm limiter amd the other is the power band, you can under or overpower your system depending what you want to do.
Personally I have a heavily modified Japanese exrace mc22 so I know the engine can handle it. But you risk blowing the engine running it overcharged, that being said you can 100% feel the difference .
I say for the money its worth it, I think the Yamamoto spec-a titanium exhaust would pair up amazing with this.
