Re: 7900 Muffler

I bought a 6421 that was a 2010 model and it had a cat muffler. It came from the factory set rather rich as did my 2010 5105 that also had a cat muffler which I changed to a 5100 muffler.

I have a 2006 7900 and it had a regular muffler.

I immediately converted the 6421 to a OEM 7900 and put a regular muffler on it. Both my 7900's have the HD filter that I installed.

I stihl have these saws.
