koa man, I've been told that you routed your stacks outside the truck, not through the box. Would you be able to post some pics please. All of the old links you posted seem to have expired.



If anyone else has done stacks that don't cut through the bed, please post pics / links.



TIA,

Stephan

This is how I would do it. If you want stacks like a truck, mount them like a truck. And I'm not talking about one of these new captain fantastic fiberglass aerodynamic trucks either. Of course it would be easier with a flatbed...

I have been pondering a single stack outside the bed as well. Coming up between the cab and the bed, mounted to the bed to keep down noise and vibration.



Has anyone doe this with the heat Shields?

Sticks - At one time, I thought I read about BigSaint putting heatshield around his single stack. Hope that helps some.

ps - what ever happened with your turbo issue - shoot me a pm.

Thanks for the link. I found a picture of MCummins stacks and decided that I don't like the out and around the outside look of the stacks (no offence to anyone, just my personal taste). Anyone know of a place that can make customized canopies?

 

[GiesJ]

Coalsmoke -

Do you have a topper or a tool box in the bed of the truck? Just wondering.

[Coalsmoke]

I plan on running a canopy (topper?) on my truck during the summer months as I do a lot of fishing and general travelling. Truck becomes everything from spare parts hauler to sleeping quarters.

MMclain, very cool pictures. I definitely think outside stacks look a lot better on a flatdeck.

I've come up with a new idea. I'll keep my standard under-the-bed exhaust for when I have the canopy. I'll just have a y pipe that I can cap off in the bed, when i want to run with the canopy. But I'm not sure how to shut off the stock system when I switch to the stacks. Are there any diverter type systems that use a cable or solenoid to choose from one side to another? I don't know what this would be called and my search results have come up dry so far. I think I remember someone else talking about one a long time ago, something that would let them straight pipe it when wanted but then muffled the rest of the time.

Somebody on the TDR had a truck w/ outside mounted stacks. They are in a thread somewhere. It's a dark colored truck Pictures are of it on the sand dunes?



Or maybe I am losing it.

This is a better angle. .



I got tired of them like that, so as soon as I finish my motor, I'm going to be putting them inside the bed. I think they will look very nice.

It's your truck I was thinking of.

 

[Coalsmoke]

They don't look too bad with the dually, but they'll stich out like a sore thumb on my SRW. nice pic though and thanks for posting it.

coalsmoke, I built a home made set of diverter valves. I can go from running the exhaust straight piped through the stacks to a mufflered tailpipe with the pull of a cab mounted control cable. I love this setup! The only thing I want to change is is to hide the tailpipe. It looks a little silly seeing a tailpipe on a truck with stacks. This setup comes in real handy when I put in my slide in camper. It takes less than 5 min to pull the stacks out of the bed and all I have to do is leave the valve in the tailpipe position. It also comes in real handy with cops. I can go from waking up the whole neighborhood to "no officer, that couldn't of been this truck making all of that noise... . see its quiet!".

I love it. How did you go about making these valves? I can figure out most of the external levers, cable, and such, but what about the internals? How do you have the valves anchored? What are they made out of? Don't the holes for the pins leak exhaust, or are they a close enough fit to not leak a considerable amount, or did you go one further and use bushings?



I've got to make a set of these, please elaborate.

I am running late for work but I did put up 3 pictures in readers rig truck gallery for now.

coalsmoke, I installed 2 butterfly valves after the the pipe splits. The 2 valves are connected so when one is open the other is always shut. The valves pivot on a 3/8 shaft. I plasma cut the valve plate from a sheet of 1/8 stainless and ground it to fit. I then attached the butterfly to the shaft with allenhead screws into tapped holes drilled into the shaft. I did not use bushings on the shafts as this was sort of a test to see how the idea worked first. I originally planed to pull the valve and re work it a little but it has worked so well that I have left it alone for the time being. And yes it does leak a little around the shafts. The real short coming with building the valves was grinding the valve plate to accurately seal off in the pipe. I was not able to get as tight of a seal as i would have liked. I am currently looking into buying 2 pre-made valves to that have a more positive seal.
