I wanted to put this out for any imput from the
"Great Ones."

I have an 8V-71 (brand new) in my Eagle O-1, with two 3" exhaust pipes coming straight out the back of the bus. One is on each side of the hitch. Now that I'm towing a toad, I would like to redirect the exhaust to have the outlet go through a hole on the right rear middle of the bumper.

One question is: Can I run both 3" pipes from the muffler ends into a larger single pipe (such as a 6" diameter),or Can I run two 4 or 5" pipes out of the mufflers without harming my sweetie 8V?

Welcome your input,

Ron

I have an Eagle 01 also. To solve the problem of exaust and oil getting on the toad, I got two chrome 3" exaust turndowns from Auto-Zone I pointed mine straight down to the road, tighten the set screws. Problem solved.

BEWARE! I had a chrome exhaust tip stolen from my car about a month ago. I suggest welding them on.

A 3" pipe has an area of 7 square inches. To join both pipes you'd simply need to keep the area the same, or at least 14 inches. A 4" pipe falls short just a bit and a 5 inch pipe is 19" so that would work very well. Of course bends and turns add restriction so keep them to a minimum if possible.

The thing you're trying to avoid is backpressure. If you were really thorough (or if you already have an exhaust pressure gauge hooked up with, for example, an exhaust brake), you could simply verify that your new system isn't adding any more backpressure than your old one did. But my guess is 5" pipes will cause no problems...

Cheers
Gary
