does anyone know if the muffler for the Tower Hobbies 46

will fit the Super Tiger 45? The description says it won't fit the ST 42 but it doesn't say anything about the ST 45.

I used a Tower 46 muffler on a ST 45 for a few years. It almost fits. Just use a needle file on the exhaust port side of the exhaust stack. It will bolt right on. Just about .020" on each hole

Thanks for the info. I was hoping it was something small like that since they both say the bolts are 36mm apart.
I'm hoping the Tower muffler will be a weight savings over the stock muffler.
Did you notice any performance gains in your engine with this muffler?

I cannot say. I never ran the engine without the Tower muffler.

The Tower muffler is a big plus in weight saving and will provide some performance. I always use a little gray RTV sealant and no gasket on all mufflers. You get max backpressure and no oil leakage from that joint now. Enlongate the mount holes a little and your good to go.

This is slightly irrelevant, but the page doesn't even mention Super Tigre, it's talking about Thunder Tiger - I don't think ST ever even did a .42.
