Stacks through a camper top?!?
Hey Guys,
I've been looking at getting a set of mitre cut 5" or 6"stacks for my truck, but did not want to give up the wintertime versatility of having my cap on the bed. So I came up with the idea that you could cut the fibreglass of the cap, fab up a grommet of sorts, maybe even something to seal them in since they don't flex, and have the stacks stick up through the cap. I think this would look bad, but what do you guys think, would it be tacky? Is there anyone with photoshop that can chop some stacks onto a truck w/ a cap?
The other question I had was whether they should stick up through the flat section of the cap, or through the sides (so you'd have a long oval line cut in the side of the cap, but the stacks would be just inside the bed rails)?
Thanks Guys,
Matt

I wouldn't do it... a lot of effort, good chance it'll look really goofy, and even better chance that the resonance of the stacks echoing inside there will drive you batty.
I know on my old 1st gen, the resonance w/ my straight piped exhaust was a lot worse with the topper on than with it off

Ahh...I never thought of that Forrest, but what if I wrapped the stacks with Fibreglass Insulation? That should keep the noise down, that and an internal muffler. I wanted to go with mitre's, that way I would just have to lift off the cap, but unclamping the stacks wouldn't be hard either.
I looked through all the member photos and it looks like this has never been tried before, at least with a CTD. I may have to give this a shot in the spring. And I think I'll put the stacks lined up with the outer parts of the sliding window, so the stacks would be through the top, and I wouldn't have to clean off the paint all the time.

Ive seen a truck with it done befor, and i posted how it was done for another guy that wanted to do it but i cant find my post on it. The guy put the 6 inch stackin threw the topper with the gromets and made a rig to secure them to the bed. But he ran 4 inch pipes up inside the 6 inch stacks to eliminate anything being burnt or melted. The 6 inch pipe stuck out a foot from the top and the 4 inch pipe stopped about 4 inches shot of that. The 4 inch was all welded and bolted to the bed so it wouldnt move inside the 6 inch and rattle. The flex pipe under the truck absorbs all the movement. Came out real nice. But seemed like a lot of work tho.

Thanks Dieselrob,
I'd love to see pics if you can find them, if not, no big deal. I kinda planned on running 4 or 5in pipe inside the stacks. I only want it to stick up about 3 inches higher than the lowest point of the mitre cut. The way I plan on doing it, it'll run just like regular stacks, then through the topper...Not a big deal as far as I can tell.
Did he have a lot of resonance inside the topper though?
Thanks,
Matt

I don't think i would do it , there is an older model powerstroke around here with the stacks right up through the extended part of the CAB. He has a stack inside a stack , that is a 5" chrome for looks , with a 3" steel stack stuck up inside to actually carry the exhaust. the tips come just a few inches out of the roof then then they are turnouts...

maybe one of those stovepipe gromets that are used to run a flue threw a metal roof would work? i would like to try this, but i too was worried about how it would look. if some one gives me a red cap for a long bed, i will give it a try, and post some pics of the deal. so, whos got the free cap?

I dont have any pics of it sorry. The resonance wasnt to bad, it was a quad cab. He had one of the carpet liners that covered the whole inside bottoms and sides and gate. No worse than a single flat cut stack like i had once. But i think you will find out if you go as low as your thinking it will be a very dirty topper roof.

Well considering I ride on 35" tires and the truck is pretty tall, I don't even think Yao Ming would be able to see it. I also thought about throwing some Rhino Liner on the roof of my cab and topper. The paint on the cab is already pretty crappy, and I do like to throw my canoe or kayak up there occasionally, so it would help to protect it. If I end up doing this, it will be in the spring/summer, but I'll keep you guys updated.

Personally I have never put stacks THROUGH the bed of any of my trucks.... I mount them outside of the box. My current truck only has a single 4" aluminized stack with a miter cut tip, but as soon as I become rich and famous it will be upgraded to duel 5" with turnouts. My first vehicle was an '87Ford F-150... I hated that thing, but for $50 and a the cost of a clutch I couldn't go wrong. I had a 4' tall 4" single on the passenger side of that beast and boy did it ever look sharp! Sounded great too, but so does everything else I pipe (I'd tell you who to ask but there's no one on here that personally knows me).
