Can tell a fuel mileage difference and slight power. Made it a tad bit loader also. Good stuff.

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.
