RE: Bench running a TT40
You guys most be over torquing the muffler bolts or something. In 2006 I bought 12 TT40 Pros and 12 SMII's, never had a problem with any of these breaking muffler bolts or any of the muffler's coming loose. this problem may be caused by the use of the supplied gasket used between the muffler and the engine. I never use these gaskets,and the people that use the gaskets usually have problems
loosing the muffler,breaking bolts due to the muffler coming loose etc. ect. etc. Take it For what it's worth.
