Hello; I am in the process of building an extremely nice engine test stand for myself and my friends to use for the initial start up and break in of our engines. In trying to simplify as much as possible, I decided to use a new reproduction exhaust manifold and then just drop down to an aftermarket
style muffler and tip; does anyone make the short pipe that fits between the bottom flange of the exhaust pipe and the inlet side of a stock type muffler?

I stopped at Midas & Meinike (local in Chicago) with my sample and both of them told me that their equipment will not fabricate the flange that mates up with the bottom of the exhaust manifold......

Anyone have any suggestions - anyone have a damaged muffler that they might be willing to part with the front section? Thanks, Steve
 
Make your own! Block of wood drill a hole the pipe will slip through, grind a taper in the wood and with a hammer form the flange. With a miss fitting flange I've reformed the flange to seal better. Something like a tubing flare tool only bigger would work

Yup - once you get it close using the block of wood use an old junk manifold to beat the perfect fit against. Ive got a pile of warped manifolds or severely pitted/blown out/broken eared ones.
 
I located a new section, but as far as a "REAL" muffler shop, they are all long gone just like tire shavers, carburetor shops, Babbitt works and other necessary services that most of us tend to need from time to time. Thanks and regards to all! Steve

I was thinking of doing the same thing, ball peen hammer, an old manifold and an acetylene torch

I took a Model A muffler to a shop that made exhaust systems. They bent a pipe and flanged it copying the bend. I had to go back and have pipe bent a little more to get my muffler to be level. Cost around $50. This is where I went: Lane Automotive Otsego Michigan

I had this one made at a "real" muffler shop, not Midas or Mineke.

I had planned on making one from scratch if searching did not turn one up, but I will be assembling the test stand for a mock up and then off to the powder coaters - then assemble for a dress rehersal. Should be intetesting to run the engine that way to break it in. Still need to build the header for it, but that's down the road a ways.
 
I was always told that to run in a new motor, you should drive it as a range of sppeds and loads within reason. How ya gonna do that on a stand?
 
I find this hard to believe. Keep looking. We have a shop that can build a complete exhaust system from scratch. I have had complete systems fabricated for both my Challenger and 'Cuda. If there is a "Racing" shop near by ask them.
 
I've had several flanges formed at muffler shops. About a year ago I had one made to weld on a muffler that was in bad shape at the flange. the shop didn't even charge me for it.
