I bought this mainly for HP and gas mileage gains. On the power front it absolutely delivers good nice throaty sound as well. Gas mileage is the only part where it falls short for me, my car tells me it has actually reduced my average miles per gallon by 3. I also enjoy driving my car a bit more aggressively so that could be it as well. Overall it looks sounds and performs great.
