I am going to be going to a dual setup and want to run one of those mufflers to somewhat duplicate my old car with GMMG. I am set on one of these two but cannot decide which, if anyone knows which one sounds deeper? less raspy? louder? etc. etc. that would be very helpful. I know the Powersticks are a little less restrictive than the Sweet Thunders but I could care less about that I just want the better sounding muffler. If anyone has any clips of their car driving with one of those mufflers please post it up, thanks
