Full length sidepipes

I looked in the search feature, but couldn't find anybody doing this mod. I want to put full length, 4" powder coated side pipes down my truck. If anybody has done in any style here, show us your truck, please. I had a van in the 70s and it was common and way cool looking.

Absolutely, he didn't understand scale and proportion, look at this one done correct and see the difference. And they need to be powder coated as not to look like nerf bars, like in a silver ceramic or another ceramic color?

It would have interesting pipe configuration that's for sure. Might be able to use stock manifolds or shortys, but would be for appearance only. I can't see how there would be any performance gained, and most likely a loss. There is simply no room. This picture shows some of the interference you would have to deal with. This system was a real power robber and lasted a week.

I've already had a Midas muffler shop (the owner) look at it and he said it was totally doable with a little creativity and would be fully functional, but he could do it.

Haven't done anything yet, had to lower it first, done that, now need headers. That's why I'm running it by here first. He's (shop owner) is only looking for business, he's not concerned if I lose power, let's be honest. So you lost power with this set-up, looks basically the same configuration that would be used for sidepipes, but looks like you exited in front of the back tires. Very interesting, why the power loss? Educate me please!

Obviously I thought this would be a better than average system with plenty of flow. Actually should flow close to twice what a single muffler flows. This might have been the problem, the size of the pipes (3") couldn't keep the velocity up high enough to provide good scavenging of the exhaust gases. Plus the cross over pipe was possibly disrupting the flow even further. All this together was very loud and I lost a lot of low end that we tried to tune back in and couldn't. Removed the duals and put the old Pacesetter off road Y pipe back on and used a single Aero 3030xl. and got the low end back but was still louder than I wanted. Replaced the Aero 3030xl with a 36" si/so straight through Magnaflow which I had a similar muffler on before and liked. It's all 3" dumped just in front of the axle. This has a distinctive sound at idle and cruise is comfortable with wot being loud enough to let everyone know something is on the move. This configuration ran 13.3 with low to no boost. The hemi apparently likes a high velocity smooth flowing exhaust, anything else you will pay with lost power. when you use long tubes you have to design a system that compliments the free flowing headers. None of what I have said is scientifically proven. But I can tell you what didn't work. Also something to consider is the pipe will have to go under the frame, this would be a real problem lowered. The only open space is in front of the rear wheel, the bed has a gap that a pipe can be snaked through. I ran 6" side pipes on a 68' Camaro that I really liked, with the exception of burnt ankles getting out.....

So, do you think you would have still had the power loss without the crossover pipe?
