Double Barrelled Muffler Mod

[blsnelling]

Someone recently reposted an old pic of a very nice double barrelled muffler mod on a 7900. I owed Ropensaddle another 372 muffler so I thought I'd try doing one for him. I don't think it turned out too badly. I do wish I had left it maybe 1/4" longer, but this one doesn't stick out at all. That's not all bad either.

looks very nice,would that be possible with a stihl muffler?

That looks great! What did you use for paint? Is it high temp paint?

Looks great Brad...get rid of the gloss paint though

i see you did not allow for screw in chokes or are they already choked? nice work.:rockn:

As long as there's room for two 1/2" pipes.

Yes it is. Rustoleum Ultra, has a nice sheen to it.

It won't look that way long

So what guage is 1/2" pipe, lol? I have been using 3/4" pipe, but there wasn't room for it with this style mod. I guess if you wanted to put them in the middle of the muffler you could.

Do you TIG those pipes on, or braze them? Also, is that regular EMT conduit?

Damn it, I still wanna see ported barrels. (at least the bottom one) and a bead. Holy crap I wish I could weld! Brad, get to the shop in the am, we got work to do LOL

Now you need to top it off with a BB and tell people that's the falling sights.

Whatever you do, just don't chrome the outlet(s). Your work may end up being confused with another guy.

I'm guessing about 28 gauge.

Nothing but EMT conduit. I use a small MIG and ground the welds down. Trust me, you don't want to see my welds, lol. I'm not a welder.

I think I'll do my next one for my saw and will use the 3/4" pipe. I'll put them side-by-side in the top middle front of the muffler. Nik, I like the bead idea

 

[rms61moparman]

The one I did for a 3400 was actually more restrictive than the stock muff.
I guess I should have left the original outlets unaltered and just added the barrels.

 

[jack-the-ripper]

Nice craftsmanship.

 

[arborist]

looks nice!!
i saw the pic your referring too,and i like the fact you cut your pipes shorter.though it doesn't quite have the shotgun look as the other,i think this is more practical for cutting.great job!

 

[little possum]

Im thinkin a side by side outlet on the 394 with the rib, and bead, maybe ported extended chokes. Nice work Brad. Sure are a bunch of creative bored people in this world.

That thin stuff is so hard to weld....You did good!!!
