Muffler swap? OS .91 surpass/ 1.20 surpass
My older OS .91 Surpass has no baffle in the muffler.
It is my understanding that the newer generation of mufflers have a baffle in them(?)
If so, could I simply install a 1.20 muffler on my .91 in an attempt to lower the sound output?
Thank you.

Greg.
Afraid not
..The muffler for the 1.20FS is a much bigger Beastie alltogether..different size threads on the header etc... you need to put the correct muffler on for THAT engine....back pressure values allso come into play.....surely you cant have a noise issiue with a little .91 FS..
