I still have to make the ends that will be welded to the crossmember that'll attach it to the frame. For right now I'm happy to see it'll fit and clear the exhaust and the transmission tailshaft.

I also have to make the support plate that'll reach from the crossmember to the bottom of the trans mount. For now, it's good to see how the fit is here also.

And the other side.

Tonight in the shop I'm almost done cutting and fitting the pipes to finish the exhaust. I think I've broken most every rule when it comes to the technical aspect of managing the flow of exhaust. It is the least normal exhaust I've encountered, pics in a couple days.

It was a very productive evening, everything fit together.

I got the pictures of the exhaust for the 57 Chevy truck.

I mentioned an idea, then another idea, then another idea. Dad wanted the exhaust cut outs. I then wanted to fulfill the idea. I had the idea of putting the exhaust tips coming out the bed steps. I was gonna use the step side exhaust tips for the open exhaust through the cut outs, while running mufflers with tail pipes to the rear of the truck.

Then I had the idea....try to use the side step outlets for both the open exhaust and the muffled exhaust, now that would be way cool.

As I mentioned in a previous post, I'm sure I have broken many a rule of exhaust technology in the creating of this system. I'm not building a race truck though, I'm building a hot rod, a rolling expression of ones abilities to fabricate.

Now a view from the front....

In the picture above you can see the electric cut out valves. With the valves closed, the exhaust is forced to go through the mufflers. When the valves are opened, the exhaust will free flow and bypass the mufflers to the rear.

View from the rear....

The exhaust tips are wrapped in tape so the scratch the finish. In front of the exhaust tips are flex joints. Since the engine will rock under load, and the frame will twist slightly going down the road, I needed something that will permit the exhaust to flex as the rest of the truck does, these flex joints are perfect.

And a view from the side....

By tipping the mufflers as I did, I made it easier to bring the bypass pipes out and around the mufflers, if I wasn't working on a truck I probably couldn't do this, the floor would be in the way.

One other thing I really like about this system is that it barely hangs below the rocker panels of the cab. It stays tucked up within the frame rails pretty good.

Now I can't wait to get the rest of the engine work done so I can see and hear how this system sounds.
