RE: What's the right muffler for my TT 40 pro??
If you use the Tower Muffler use JB Weld on the foints and through bolt to keep it together. It will also seal these joint to prevent the exhaust residue from blowing out. I first tried the JB weld to keep the rear piece from rotating and now use it on all mufflers. Just figure out which directions you want the stinger pipe to point before the JB sets up as it will be permanent.
