Is it just me or do other people have trouble keeping end caps on their exhaust?

 

No trouble yet, did ya put locktite on the set screws and tighten them until the pipe started to move?

 

Yes I did maybe I just need a stronger loctite.

 

You tightened 2 set screws in each cap correct?

 

I got my end caps back in April and I had trouble putting them on. The set screws that FM sent were a "new style" that were rounded on the end where it indexes the muffler. I called to inquire about my installation problem and Keith told me that they tried a new style of set screw but it really was not working. He sent me another pair of set screws that had a more pointed end. These worked just fine. A dab of blue and tighten them down to where they just begin (barely) to distort the muffler. Perhaps this is your problem.
