Exhaust out the rear

Background:

My exhaust was very loud at one time (now it's just loud) and I thought running the tailpipe out the back of the car might quieten it down some. Here some pictures of what the pipe looks like and how it's positioned on the car. It didn't make the exhaust much quieter in the car. The longer pipe does cut down on some of the high pitched raspyness of the exhaust though.  The shape of the pipe is such that I don't burn my leg getting in and out of the car.

This what the tailpipe looks like out of the car. It's made from stainless steel pool ladder pipe. The straight section is positioned about 1" from the lower chassis tube.
 exhaust to tire

This picture shows how the pipe is positioned to go under the fender and parallel to the side of the car and the tire. The pipe also has to be inboard of the link bracket on the axle tube.

The ground clearance is reduced by the diameter of the pipe but  I haven't had any trouble with it yet.

I couldn't run the pipe any higher because it had to go out the rear of the car beneath the chassis so the axle wouldn't hit the pipe. The axle can rest on the lower tubes when the frame is jacked up.
 exhaust top

And here is a top view . Notice how the pipe is almost under the chassis in the area where your leg will be when getting in or out of the car.

I don't even have to think about protecting my legs when getting out of the car after a ride.

This is how I mounted the pipe to the frame. I used two muffler "C" clamps with two long bolts. The round black objects above the clamps are rubber insulators which have 1/4" x 20 thread for the two clamp bolts to screw into.

There are another two 1/4" x 20 short bolts that go through the flat sheet metal that is located on the bottom of the chassis  to hold the insulators to the frame.

The insulators might have been part of a radio shock mount.
