That looks great! What pipe material is that? Where did you buy? And is that silver soldered on?

That is stainless pipe and I think that is a stihl 362 or 361. I can’t remember!

Easy peasy. The 395XP, and Dolmar 9010 are far more difficult.

I didn’t think those were bad to do, the 7910 ones suck

I completely gut those. And the 7910. None of them are as easy as an 044. LOL

Dave, big thanks for posting this. Doc sent me a deflector, I wasn’t sure how I was going to attach it to a new G660 muffler. This technique and materials worked great.

Torch used was air/acetylene. Note how the brazing material flows into a nice fillet where the parts join.

Best results are obtained when all paint/dirt have been removed and metal cleaned with acetone before heating. Any oxidized contaminants will weaken the joint.

This video has some great tips also:

Made a video of how I braze a deflector on a muffler.
Thought I’d share it here, may be useful to some.

That's fn sweet man. I mig welded my 026 muffler. Can be tedious with grinding and all. That braze looks nicer.

Paint was VHT Flame Proof Primer and black Rust-Oleum High Heat top coat
