If you looking for "Super dupa low-deep tone" you can try out HKS, cheap while branded, but take caution of vibration.I personnally favor Apexi's Catback, rich sporty sound (not like crazily loud)looks good too, but you will need some fitting.If you looking for power, Cattman would be a very expensive but great choice.
Just personnal opinion But look it up on youtube, see what kind of sound you looking for, compare them
