Take the fan off too. Chuck an electric one on. Fan will normally suck about 3 - 4 horsepower.

Yes 8% is a huge HP gain and if you can get that much from exhaust it would be totally worth the loudness.

Sure you might get another 8% at the wheels with a big exhaust on acceleration but ask yourself if it's really worth wrecking your ears for?


By contrast going from 9:1 compression to 11:1 is only worth 6%.
