660 Muffler Mod..

[STIHL038MAN]

Here's my effort... Welds and high temp paint job are a bit ruff but I can only get better..

If your wondering the stock side port has been welded over so it's all coming out the front and the baffle is totally removed..

Good work but I've had issues with forward ports getting close to the log and choking power, I shoot them out chain side at about a 30 degree forward with best results

Yeah I haven't noticed any loss of power when dogging in and as for the side port I close them off because I hate the way the exhaust fouls everything up..

Looks very good.

I havent noticed power loss with forward ports but absolutly despise the exhaust droning off a 4ft tree while bucking. I to go out the side over the chain.
I dont much mind forward ports when bucking smaller wood with a long bar..

Got any more pics of your set up
