Idea for a muffler mod for a 372XP??

[coxy74]

Hi there all,
I have a 372XP that I want to do a muffler mod on, but want to run the idea past everyone on here to get their views first.
I have old 066 Stihl muffler from one of my old work saws, and was wondering if I could cut the side off that ( with deflector, screen etc ) and then cut the side of the Husqvarna muffler out, and then weld the Stihl muffler bit into place?
Now my questions are, A : would this work? and B : with the new outlet hole size, plus the original outlet hole size, would the combined size of both of them, would that be to much of a opening for an outlet?? ( hope it all makes sense )
Thanks
Paul

IMO you would be time and money ahead to get a Husky 266 deflector and screen and fasten it to the side of the muffler (via screw and rivet nuts or braze it on).
Make to opening in the muffler as big as the deflector will cover.
Husky 266 deflector part #503 58 99-01
Spark screen part #503 40 56-01
For both it will be around $15-17.

Here is a picture of my 372. I added 2 cause I was experimenting a little. 1 extra port will give you good gains.

The ideal muffler mod is a larger muffler - the question is how practical it is.....

Unless a person is doing tree work amongst houses/buildings what is not practical about it?

2171 muffler I did. Same as 372

372 on right.

I opened as much as could under the stock deflector.

It would usually build forwards, as the added volume has to go somewhere, and the options are limited.

Can you dumb that down for me Niko?

Pretty practical if the environmental gestapo has it choked to death.

Not really, not even to myself - it is my brother that sometimes builds those special mufflers, some times with a "short pipe" in them....

Hardly - he was ran off this site well before he posted any pics, because he happened to disagree with some well integrated members on a completly different topic.....

He may come back though.

Here's one I saw somewhere and thought it was good idea. It's not mine
