Lambretta Stainless Steel Stepped Repair Stud 8mm to 6mm 17x13x11mm For Crankcase Side Tail Pipe MBP0278

This Stainless Steel stepped stud can repair the lower exhaust tailpipe thread if it pulls out.  With a 6.5 or 7mm drill bit and a 8 x 1.25mm tap, drill out the hole, tap down to slightly shorter than the measurement of the 8mm end and screw in the stud by locking two 6mm nuts together, tap it a bit at a time so when its home tight the flat edge is flush with the gasket face.  On final fitting use loctite.
