Best way to connect side pipes, to achieve best flow for high performance engines. | Joined: Apr 2013 Posts: 108 member | OP member Joined: Apr 2013 Posts: 108 | Now that I'm going about building this higher performance race engine for my van, I figured I should update the exhaust system. Right now I have it set up using a similar method to this: I just don't feel like the flow is very good though, my last engine could feel the difference once it was done. The full 180 into a 90 degree turn I don't know... Anyways I was wondering if anyone has a good way to hook up the side pipes that might help the engine flow/run a little better. Any suggestions or pictures would be great. Let me know how you hooked your side pipes up and if the engine could tell!

If That is IF i hook them into the headers I don't expect massive performance improvements. These are for looks mostly.

That's kind of what I was thinking. Just run the pipes as is with some cutouts, or just leave them there hanging with a complete different exhaust system under the van.
Is the method I showed really the standard for installing side pipes with all the bends? | | | Re: Best way to connect side pipes, to achieve best flow for high performance engines. | Joined: Jun 2010 Posts: 1,105 Likes: 1 old hand | old hand Joined: Jun 2010 Posts: 1,105 Likes: 1 | Hey 383, I did the middle picture, "V" engines. It's out of a '76 van mag! Right bank to left pipe and right bank to left pipe. It helps with the bluing of the pipes since it cools down before it gets there and the main reason is that there isn't real tight bends as in the "U" pipe you show. I am running 2 1/2" pipe. More then enough for the 360. Nice low mellow sound until you get into it. It's an idea that so far works for me.

I saw that picture/ad the other day when I was doing my research of how people hook their side pipes up that actually flow.
I think that would flow pretty well and I could run them through my side pipes!
I just can't seem to figure out how I can do that with my after market headers that end up at the same level. I also would like to see how exactly you can do that with the front drag links going so far back on these dodge vans.
Seeing your van with the start of your side pipes very close to the front tire like mine are, I'd really like to see how all your under workings are set up! | | | Re: Best way to connect side pipes, to achieve best flow for high performance engines. | Joined: Jun 2010 Posts: 1,105 Likes: 1 old hand | old hand Joined: Jun 2010 Posts: 1,105 Likes: 1 | No problem!! I used headman block huggers because as you stated the standard headers are too long. They use to make a set of headers that were basically in the middle, not to long, not to short. In other words a perfect length!!! I believe that is what they used in the article! I don't have the equalizer tube on yet, wanted to see how she drives with out it. At this time she has a semi stock 360 and does fine with out it. Maybe if I cam I will have the eq tube put on.

I'm totally down to get some block hugger headers, but I really want to see how it all hooks up under there >.<. Let me know if you can take a few pictures under there, or at least a few more descriptive diagrams of how they criss cross/how they pass the front swing arm drag link. It almost makes sense, but I really still can't see how all of it lines up >.<!! | | | Re: Best way to connect side pipes, to achieve best flow for high performance engines. | Joined: Apr 2013 Posts: 108 member | OP member Joined: Apr 2013 Posts: 108 | Thanks man, honestly you're not too far from me. I might be down to drive up there and check out your awesome van, and maybe pick your knowledge about a few van things! | | |
