Is that opening a pipe thread fitting along with having a 2-bolt flange on the outside?

Yes. Threads inside, 2 bolts outside.

I remember I had one just like this where I bolted on a mini-bike muffler I found. It stuck out about 3 feet and looked ridiculous so of course it was going to catch something and break off at the bolts. Luckily for me, I was still able to just take some plain ol' plumbing pipe and screw it in. Eventually made a Y out of the pipes. Sounded pretty cool.

Either one of these will work, just as an example.

I'm not kidding when I say that I've done this.

Except I literally just screwed it in.

 

[david34]

what size do i need

 

[chancer]

3/4" gas pipe.
and I have also done that. but I put a bend in the pipe and welded on a muffler like the one shown above.

I was going to ask because I wasn't sure if it was 1/2" or 3/4" pipe thread. Growing up, the Cub Cadet up the road from me had a pipe like that for an exhaust system. A short piece coming out of the engine, a 90 degree elbow and about 12" of pipe sticking straight up. Man was that thing ever loud. It was a 16HP Hydrostatic drive. That was a cool "garden tractor". We only had the 12HP 3 speed with a clutch, not near as much fun and I always lost at racing. But the other guy cheated because he could push on the governor and I couldn't because of side panels.

Yep. Put a T at the end, 2 3" pipes out of that, elbow on each end, then another 2 3" pipes out of those. At least that's what I did. Be creative with it.

A terrible sketch of what I did. Not sure what it did, but it did make it sound pretty awesome with the dual pipes.

Well, stick one of these or the straight version of one of these (Can't think of the name, nor can I find a picture of it).

And screw a muffler on it. Should cut down on the loudness.
