Has anybody heard anything about the Thermal catback for the xB? I know it's yielded some awesome power gains for my friend's Civic and even my one friend's Saturn (weird, but whatever floats your boat). And, of course, the sound of Thermal has always been great from what I've heard. I know the power gains won't be too significant, but I'm just getting an idea if anybody has any knowledge of the performance and sound of this catback. Thanks a bunch!
