What I've done is take a straight piece of sprue, and shape the ends with sandpaper. I stick it in a drill so then it is more symetrical B)

Sorry, forgot my preferrences has been changed on the forum. LOL. Sorry. Here it is copied over from there.

Alright, I have a couple of projects where I want high performance style mufflers. So while in the city today, I picked me up some aluminum to go with my brass. To do this, you will need a small ruler like a engineers 6" ruler, a small flat file, a round one, optional, a methos of cutting the metal tubes. I have a small miter saw from Ebay($35). Also, something to glue them together like epoxy or superglue. I am using 1/8" brass tubing and 3/32" aluminum tubing. These equate to a scale 2 3/8" exhaust pipe and a 3 1/8" muffler. For better realism, you could use alminum tubing for both and polish. You could also use styrene if you plan on painting them! Here, I cut the brass to 1/2" or a scale 12" length and the aluminum tubing to 5/8" or a scale 16". Then use your file to smooth the ends up and to round the ends of the brass piece so that it will blend down into the pipe so when you glue it, it looks like a welded piece. Now slide the brass over the aluminum tubing and glue. Make sure to leave 1/16" of aluminum showing on both ends, or a scale 2" length for clamping the rest of your exhaust system together. Thank you! Jody

That's cool Jody. Thanks for sharing.

Benjamin - The Revellogram '37 Fords came with glasspack-style mufflers that measure 1.25"(30" in 1/24th-scale); I have a pair that I wouldn't miss....you have a PM, sir.

Thank you very much! I wanted a more realistic looking piece. I got tired of trying to sand out flashing and ending up with something mis shaped. I do not have many tools so I needed to come up with a simple idea!

I made mine with the plastic tubes from two cotton swabs. I found some styrene tubing that fit nicely over the tubing from the cotton swabs and I cut it to the length I wanted and rounded the ends. After sticking the two together, I flared and angled the inlet and outlet pipes, painted and weathered them.

The brass item is the driveshaft. I had lengthen it because I lifted the rear of the car.

Since I made them with workbench scraps, I don't have any specific information on the materials I used. Hopefully, this will give you one more idea to work with.

I also did the "little tube inside the big tube" for my glasspacks. Mine however are the header style, so I added a flange to one end and a turndown to the other. I find the easiest way to make a turndown is bend the tube at like a 60 degree angle and cut through parallel to the muffler body.
