I’m currently restoring a 1936 suburban that sits on a 1936 FB chassis from the factory. I was able to source the exhaust and tail pipe from this individual (martinjohnsonvintageexhaust.com) but have not yet tried them for fit.  The Jim Carter truck catalog lists the muffler.  Mike

If you have a Suburban, Canopy or Panel, DON'T use the stock exhaust pipe. Make sure it empties BEHIND the rear wheel to the SIDE or you will be breathing carbon monoxide due to double wall construction. I speak from experience.

Lou,  It appears from the existing hangers on the 36 suburban the tailpipe exited straight back underneath the rear bumper.  Are you saying the exit point is where the hazard is?  Thanks,  Mike

YES! Single unit trucks have double side walls with holes below floor that cause any fumes released under or near the rear to end up inside the cabin. Even the Sedan Delivery does that. Surprisingly, so do the Canopys. Several years ago, a fellow in the GM truck club drove 200 miles with his family in an Advanced Design Burb and they all were in the hospital with carbon monoxide poisoning. If you drive with your tailgate or lift gate open, and your exhaust does not exit out the side, it will also fill with exhaust. The parts book shows #593744 for all commercial and trucks but you want it to exit to the side beyond the fender. I get a muffler shop to do my exhaust pipes.

@lou-macmillan Here in Aus the rules state the exhaust must exit at least 6" rearward of any passenger compartment opening. With this in mind sedans and suburbans the exhaust must go to a point near or beyond the rear bumper but trucks and pick ups can exit anywhere behind the rear of the cab.

Hi Tony

We have the same rules here.

The exhausts on our medium duty grain trucks exit just behind the cabs, as per the rules, and we never get even a hint of exhaust in the cabs.

Even when sitting still and unloading.

Now... the leaky gasket on the fuel gauge sender on the tank under the seat of my '46, THAT was different.  🙂
