Model 10C Exhaust

Recommended Posts

My 1925 10C Demi muffler is corroded out. The 2" front pipe is good, the back 1.5" pipe is rough.

 

Is the most practical solution is to get a modern 2 inch inlet/outlet straight muffler, cut out the flanges, use modern connectors/hangers and have a muffler shop bend the now 2 inch tail pipe . The car is a driver

 

Thanks

Art Lee

I'd go with  that.  Did it on my 147 using stainless flex for the tail pipe.  I think it will be louder than a1.5" though, so you could use a 2 to 1.5" reducer and 1.5" pipe.

I bought a complete exhaust from Waldrons for our 10C a while back. I had to heat and bend the tail pipe a little, but otherwise it fit and it sounds great.

Do you have any pictures of the pipes before you put it on?

 

I'm curious about how well they make the bends - i.e. how much are they compressed/squished as you get from push bending?

 

I'm in need of front and rear pipes for my 11A, and the 10C at the Franklin museum also needs a front pipe and muffler.

I do not. The pipes are not mandrel bent, and are not pretty, but they work.

Thanks Steve - I'm still pondering on what to do.

 

Maybe I'll try André's "how to bend a pipe by filling it with sand and then heating it" method.

Ever try an electricians conduit bender?  Bet you can rent one pretty cheap for the day.

I've quickly explored the idea - one problem is that electrical conduit sizing isn't the same as exhaust tubing.

 

Exhaust tubing is 2" OD, but electrical conduit is actually larger than 2" OD - more like 2.2 or even over 2.3", so the dies and rollers in a conduit bender won't be exactly the right size to keep exhaust tubing round as it's being bent.

 

The other thing I have wondered about is if this tubing roller from Harbor Freight could actually do it

It supposedly comes with dies/rollers to handle 2" tubing, but I'm not sure just how well it can do the job - there are videos on YouTube of people using them with seemingly decent results.
