Actually, the cat back will be pretty much the same on performance but different on the sound. Full cat back will only give you about 2 or 3 over just a rear. Look around, this is told many times by other people. OBX has been here for a long time, its just that they used to be so expensive that not many have had them, but now, they are cheaper so its getting out there more. OBX is of great quality, and maybe you should ask around more before you knock something! Many from this forum have ordered OBX from me and have had no complaints! And an "axel back" is a 3/4 not full cat back. :alien:
