Hey guys. I am going to be getting some kind of cat free pipe after Christmas, but I can't decide what I want. I have had O/R h pipes before, and they were great, nice power, nice loud sound. I have heard alot about X pipes and pro chambers, but I can't decide what to get. If I get an H, it'll probably be like a Mac or BBK, if I get the X it'll be Pace Setter, and obviously if I splurge and get the prochamber it'll be Mac. Let me know what you think of those, my exhaust is currently Mac 1 5/8 shorty headers, stock H, and Flowmaster dual chambers. Thanks guys! Also, if anyone has any experience with Pace Setter, post it, because I can't find much on them, but their prices are good.
