Do mufflers work with the flow reversed?
 

I read a bit on three chambered mufflers and they talked about sounds bouncing back and canceling the others out. It was a bit too much for me to digest. So, if I install a muffler backwards, what will happen? Thanks!

Don't run chambered mufflers backwards. That would be a flow nightmare.

You can run traditional glass pack mufflers backwards. The ones you can see
through. There is a slight flow difference from what I recall.....

In JWL's book. He goes into detail on the effects of stock and modifies exhaust systems have on performance . One example: Dual exhaust has no effect on performance over stock. and there is more.

Funny, it has been well documented what happens when you play a beatles record or a country music record backwards. Maybe someone will record a backwards muffler and we can all chime in.

Hmm " I buried Paul" actually "Cranberry Sauce " and "We **** you like Supermen " off Sgt Peppers . Paul (or Billy Shears if you believe I buried Paul) is on record as saying " its definitely there but we never put it there "
Spooky ?

The person who built my avatar motor at sometime in the past found that Fenton cast headers made less HP then stock exhaust manifolds on the Dyno. Which points to the fact that flatheads have terrible breathing problems and most of what you do may or may not help. On my avatar engine he built nice equal length headers to fit the 32 frame and I really have no idea if they make any difference. Didn't Dyno it with different exhaust. The car is quite responsive though. I think his proprietary cam grinds have more to do with the performance then anything. He has the cam lobes ground at 114 degrees instead of 110. Flatheads don't like overlap.
I think there are pictures of the exhaust system in the album of 32 roadster pictures. Stainless steel tubing with Edelbrock Stainless mufflers.

When you try it let us know how it goes.......it will depend on the muffler design....most are proprietary technology, but some are not. Some are straight through with the baffles oriented toward the front to catch the flow/noise. Installed backwards they should make the exhaust sound louder since the baffles will have little/no effect. chambered mufflers will flow in reverse, but might be less efficient at higher RPMs.

Most manufacture's have a spec. sheet for each style muffler they make, and most will tell you if it is 'reversable" or not. Should be able to find the info you need online.

And if you visit the cemetery in Vienna, Austria and stop off at Beethoven's grave and hear one of his symphonies being played backwards, it's probably him decomposing.

Yeah, right Graeme, good one. Regards, Kevin.
