Default .91FX Muffler vs .61FX Muffler

Dear Ann Marie,

I have a new .91FX installing in an AT6 with retracts. The long shiny insert in the .91 muffler makes it stick back so far it interferes with the wheel retracting.

What are the bad things about using a .61FX muffler. I have one of those and it fits great. Should/could the baffle be removed - on either muffler?

Alternatively, could I turn down the shiny extension a bit, say make it about 1/4 inch shorter and it would let the gear retract.

Thanks for you help. I LOVE OS engines!!!!

Default Same question

I have exactly the same question. I want to put a 61fx muffler with the baffle removed on my brand new 91FX. Will I lose any power? Thanks
