I know a guy that has done a few of these on GT500's. What was fun to watch was how you did it. You mentioned you had to 'tweak' the pipes in order to get the QTP setup to work. I could see that was going to happen before you got them. That was something I had to play by ear as well, as QTP hadn't released the completed kit yet but I managed to convince them to send me a pair instead of waiting for instructions to be included, etc. I guess no matter how you do it, the Boss pipes really add to the experience. They offer a growl that no other conventional system can.
Alex, your work is first rate. The attention to detail, the cleanliness, etc, just what a caring S197 owner would want. Keep up the good work!
