The muffler was tapped onto the head pipe to check for the proper length. After testing the fit, we found we needed about 4 inches of the head pipe cut off to make everything fit properly. Four clamps and eight bolts secured the system. JBA recommends tack-welds to be extra sure everything stays put. The grand total time for the exhaust installation was 15 minutes, and that's being conservative.
