Where did you get that Pipe and how long have you had it? FTZ makes a few different In-Frames and as far as I know they will built a custom pipe that matches your motor and your style of riding. I hear the FTZ Fat Pipes referred to as FTZ Whale Pipes a lot on some of the older forums. I'm looking for the BIG Hi-Rev In-Frame Pipe and I'd like to get their FTZ XC/Woods Oversize Alloy Silencer. I've got the word out on all the forums but I haven't had but one guy that said he had one and he wanted $800 for it. I don't know if he was being serious. Please continue to keep me in mind if you happen to run across the pipe I'm looking for.
