H Pipe Installed
I had been reading a bunch of the posts regarding the h pipe and finally had one put on this past Friday. I have the Mid America chambered exhaust on my '74 and what a difference installing the h pipe made. I liked the sound of the chambered pipes, but the low resonance while traveling at low speed made it almost unbearable. Now that the h pipe is installed the sound is awesome all around. I can actually hear the radio again, and the annoying "brap" sound is gone. It now has a nice throaty performance sound.
Thanks to everyone that suggested the h pipe.

I wish I would have taken some pictures while it was on the lift at the muffler shop. I will see if can get a shot of it now that it is on the ground again, but I am not sure if you will be able to get much of a view of it.
The guys at the muffler shop actually told me that they did not think it would do much, if anything regarding the sound, but for $35 including the pipe and labor, I figured I had nothing to lose. After about 1/2 block down the road, I called the muffler shop to let them know what a huge difference the h pipe made. Prior to the h pipe the exhaust had a kind of cackle or brap to it, and at low speeds the resonance would actually vibrate the grilles on the rear deck. I am still amazed what a difference the h pipe made.
If you are looking for a picture in the meantime do a quick search for h pipe and sort by heading vs, in text. There is a picture of an h pipe already out there. The one in the picture has a flanged joint that can be undbolted in the middle. The one I had done was simply welded in but was placed in the same location just beyond where the pipes cross through the framerail prior to the chambered sections.
