Review on Nicecnc Exhaust Muffler 1P39QMB Scooters Motorcycle & Powersports by Carlos Macy

Where you will use the three main bolts to attach the exhaust to the pipe, one of the bolts will thread into the spot where the bracket goes to the side of the bike. So you can't get any tools on it, not even an Allen wrench to tighten the bolts as the flange/bracket that connects to the bike is in the way. There is only 1 inch of wiggle room to do anything with this screw.
