I'm curious if anyone could tell me if they could tell a noticible difference with a switch from an EZ to the newer Qaudzilla for a 2000 mod. I now have a EZ on my truck and it does make a big difference but like most I would like a little more without worrying about egt problems. Also how does the CATCHER effect egt. My truck is stock other than EZ, gauges, straight pipe, and exh. brake. Thanks in advance.
