OK, maybe 2-5 hp, but it sounds great. Yes, there is a drone between 2-3000 rpm under load, but a shift cures it. EZ install and the dual tips look great.

Because of the vented tips the sound of my turbo spooling has a higher tone giving it a supercharger sound. It is quiet when it needs to be but still has a nice deep tone that I love! Would Buy again... I may end up buying two more later and doing quad tips
