Headers Without Rasp Yet Solid Gains

Sorry if this topic has already been covered, but what I am wondering is this, I am interested in installing a set of careless headers but don't enjoy the raspy civic sounds that comes with it. I understand that it is due to being catless but that is also where the gains come in. So what would be the best solution to have the best of both worlds ie good power gains without the rasp?



Thanks
