Ok guys, I have gotten use to my current exhaust sound and now I need it be louder, the answer (i think) will be high flow cat. My question is, which Hi flows are good quality or are the best for a sixer? Or are they all the same?

I have been running Pypes for about 8k miles, but I went from an offroad H to Catted H to cut down the sound. They cut down sound but diffinately louder than stock. Good price too.. .
