A few stack questions

First I would like to say that FordT has got me in gear to do my stack idea now. :bow:
So my truck has one of those roll top covers that covers the bed. My idea was to possibly take the part of the unit where it rolls up and slide it back aprox. 7-8 inches and run 5 or 6 inch mitres. I was then going to cover the 7-8 inches with some type of plate to match the black cover and have the stacks coming out the plate looking all nice and flush and smooth, still having the cover. Now the questions.

1. Will the heat from the stacks be a problem for a bed that will be inclosed and lined with a rhino liner?
2. I wanted to use like a high temp silicone around the plate and the stacks to still leave the bed water tight. Any problem with this?

Basicly I'm lookin for feedback. I think that it could work but I am alil bit scared of the heat being trapped in the bed. What do you guys think? Thanks

Lovin

On edit ya'll from fordt's post that could be looking for a makeshift cat back exhuast I would be selling the rest if I do this. Lemme know!

First off, you can buy just the peices from MBRP that you will need. Originally I was gonna put a full exhaust on, but with the 450, it would not fit.

I think if you moved the roll top back, put a wall up 7" from the front of your bed, this way it seals off everything under the roll top, then go with some 5" mitre's, IMO anything bigger is too big. Then you will have created a cavity for the stacks to go, and get you something to cover that top, and WAMMOOO you got some stacks. Don't forget the smoke :smoke:

You will need the downpipe, cat delete, if your gonna do that, and the next peice, whatever it's called. Nothing else. Unless you want a muffler, then your gonna have to do some riggin. Then just buy a kit with some stacks, it should come with the elbow and flexpipe.

sounds like a great idea, except for the silicone, just make your holes 1/4-1/2 inch bigger than your stacks and leave it, the amount of watter that will get in there will be slim to none, and i don't think heat will be a problem, i will get a pic but a kit i know has a 1st gen dodge, he customized a fuel tank so his stacks run through it, the stacks are only 1/2-1inch away from 100 gallons of fuel and no probs yet

Fordt, I already have a full exhuast.. I was just goin to fab up the rest on my own really because it would be hidden anyway. What about the rhino liner. I called them and they said that it should be good up to 200*. Do you think that would be a problem? Thanks. I think I am going to do it over my spring break.

Excellent, I'm pretty sure i'm goin to do it. :smoke: All thanks to your motivation. Rob, I found some 5 inchers for only 30 bucks, so unless i can find a better deal sometime, looks like it'll have to be 5's. :

Thanks Guy.

How's it going LovinPsd, good I hope. I think I may be able to answer some of the questions you may have. While I'm not sure of the exact temp. of the Y pipe of the stacks, I've been told its near the 300-400 deg. range. I am looking for more info on that my self. As far as the bed liner goes, I had the same question about the LineX brand. They told me to do a heat test. Most of these place's have a square piece of metal they will throw some on, and you can do a heat test at home. Again that is something I'm hoping we can do here, for reasons like your question! Not sure about the silicone Idea. I'm not real sure on what kind of silicone can with stand that kind of heat, and then a cooldown. I would be interested in finding that out though. Check out our site, we have stack kits avalible, and we have distributors everywhere! Give me a call or email! Hope this helps you out.
