I'm totally giving away that I know very little about cars, so bear with me. ;)

 

I'm currently working on a '65 Chevy stepside from Revell, and the instructions show only a single exhaust pipe from the left manifold. I'm curious why this is? Not only from a model perspective, but also for the real deal. Does that mean the other manifold would somehow connect together at some point or does it stay open near the engine?

 

Also, I plan on having a dual exhaust system based on the 1:1 I'm modeling after and the exhaust pipe ends where the muffler is at––about halfway down the frame. I'm curious how one might go about scratch building one of these?

 

This shows what I think would be the dual exhaust about half way down.

Thanks, guys.

On a V-8 single exhaust, a crossover pipe ran from the right manifold to the pipe on the left side.  For some crazy reason Revell neglected it.  It would be easy enough to make with some styrene tubing.

Yeah, Lee is correct. And don't worry about showing your lack of mechanical know-how. You are not alone in that regard here. I have big block headers on small blocks and vice versa on some of my early stuff. And there are plenty of guys WITH the knowledge who are understanding of this and willing to help out if you ask.

Thanks so much for educating me on the issue. I had a feeling that the right would connect to the left. I will take note not to learn how to build a 1:1 from model instructions. For those of us who like to build prototypically, it kinda sucks to see something like that. Anyhow, good thing we got forums.

 

Thanks, Phillip, for showing the underside. That is really helpful. I'm assuming that is scratch-built? Where would one find the mufflers? Or do you usually take from other kits?

You can steal a complete dual exhaust set up from another kit. Sometimes you'll need to bend it a bit to make it fit. You can bend it with a little heat.  Also I will cut the pipes and mufflers apart, drill a small hole in each and insert a small length of straight pin into it so I can roll and adjust the parts just like you would installing a real exhaust system. Once you've got everything lined up, you can add a dab of glue to hold it all in place.

The pin technique of assembly.

Here's an exhaust pipe that's pinned together. There is a short length of cut straight pin between the pipes and muffler.

And here it is assembled on the model. You'll see that I wound up modifying and adding to the front pipe to clear suspension components. You can see how I pinned it to the chassis, and sharp eyes will see it took me two tries!

Thanks for chiming in, Tom. That is an excellent idea using the wire. I will look around for a duel exhaust system. Just one more thing to add to the list. As always, thanks for your guidance. At some point I'll actually have something to show. :rolleyes:

Burt ask as many questions as you wish. Better to ask a question than have to rebuild something .

I'm glad you asked the question, Burt.

 

I learned a few new things from this thread!
