New Dolmar 7900, is it really useful to mod it?

[CapitaineHaddoc]

Hello everybody!

My name is Guillaume, and i'm a french lumberjack.

I always used stock machines until now, in my country every pro lumberjack used Stihl or Husky.
Last week, my chainsaw dealer propose me a Béal TR790

Tronçonneuses EXPERTPRO-TR790, Marque BÉAL - Yvan BEAL

As you can see, it's a Dolmar 7900.

I look on the internet, and it seems to be a great saw, and i can buy it for a really good price, so i buy it.

Then, i discover this great forum, and after a lot of reading, i have a lot of questions:

-I see many 7900 with modified muffler. Is that really efficient for a working chainsaw? It's not too noisy? Can i do it myself?

-On ebay, i see this:

Custom Modified Dolmar 7900 Power Ported Chainsaw Muffler | eBay

But the seller say that's only for exhibition, is that true?

-I think i will order that,

Chainsawr Dolmar 6400 - 7900 Chainsaw Heavy Duty Air Filter Kit 957 173 400 NEW (D-Bulky2)

I can't find it in europe, is it really better than stock filter?


In France, nobody mod chainsaws, but it seems really interesting. Thank you in advance for your answers!
