Overall install was very easy no more than an hour the performance that I found was better throttle response and feels like more torque also sounds nice

I bought this spacer to improve hp and throttle response, i did notice a whistle sound from 2500 to 3000 rpm and also more hp when accelarating. It is not a huge improvement but i did notice a little more than stock.
