Hey All,

Happy New Year. I am hanging exhaust on my truck and I am wondering how low below the frame does the exhaust pipes go? I am thinking about 5-1/2" looks about right but I cannot remember how it was before. Actually before, the exhaust systems was all patched together so it probably was not a good reference.
The running boards are about 5-1/2" below the frame so that is what I am basing my estimate on. Anyone done this before?
thanks,
skipper.

It might help to know what year and model truck you're working on...

Oh yes, its a 1950 AD 1/2 ton.

Skipper,

Are you hanging a stock single exhaust on your 1950 AD 1/2 ton? If so, the manifold down pipe will determine your drop of the exhaust. From the manifold down pipe the exhaust will begin to tapper up to the muffler mount on the frame. Suggest you use a light coat of grease in the pipe ends so you can adjust it easily so it will fit tight and properly.

I am not hanging a stock exhaust. I have bought a tubing kit from summit and I am building my own exhaust. I am using the thrush turbo muffler as I hope it will be semi-quiet. I do not want too much of the exhaust hanging down where it can be seen.

Skipper,

Talked with a very good friend of mine who has bent custom exhaust for at least 20 years. He's now retired. John said to start at the exhaust manifold with a GOOD tape measure and the drop from the manifold will determine your initial drop. Take a lot of measurements and mark the pipe where it needs to be bent with a line and a "B" and where it needs to be cut with a line and a "C." Get it as close to the frame with about 1/2" clearance. From the main exhaust pipe keep it level with jack stands and mark where you will need to mount the hangers. He suggested to use hangers that have little to no movement up and down and only 1/4-1/2 inch lateral movement. The new type welded stem hangers with rubber bushings are best for this. Measure a lot and make sure your measurements are exact before you bend or cut. Best I could do without actually seeing what you exhaust plans are. Rear exit, side exit, just behind the diff exit? Hope this helps.
