I have American Racing 1 7/8 headers and started catless but eventually went with some Vibrant Gesi High flow cats.
The Highflow cats won't really make much of a difference in the volume of the sound but will refine it in a good way, reduce or eliminate any rasp and eliminate that awful smell that no cats force you to deal with.
