lol no problem buddy. We were all new at some point. First take one of the rubber gromets and install it on the chamber part of the pipe with the flange seating against the flange on the pipe. Then join the 2 pieces together and line up the 3 small holes that are on each flange. Then locate the 3 small springs and bridge the gap between the header and pipe. Then take the second gromet and install it on the motor and attach the pipe and use the long springs to secure the pipe by wrapping them around the case below the cooling head. Make sure those springs are as straight as possible in relation to the header to make sure you have a good seal on the exhaust flange. Thats about it dude. Good Luck
