do the .46fx the 50sx and 55ax and tower muffler all have the same exhaust bolt pattern?

I know for a fact and from experience that the 46FX, AX and 50SX all have the same muffler bolt pattern.

I've never had a 55 but someone on here stated that the 55AX uses the 46AX Power Box muffler

And on the Tower site it says they are the same

The 46FX and the 50SX are a lot alike especially on the outside

I've seen the .50SX run with the .46FX muffler. The Tower muffler will fit it too. I would like to see one run with that.

YES, it is the same...
I have a TOWER muffler for a 46 on my 55ax...
bolts up perfect...
