Home made Stack?

[tech701]

I'm going to make myself a stack. Here's the idea...... I want it to be six to eight inches in diameter on the passenger side. I'm going to paint it black. I'm going to cut out of a piece of sheet aluminum the words "Global Warmer" and attach it vertically on the stack facing the rear. I may put a flapper on it if I can weight it right so it will ting at idle. My question is, what can I use for the stack? I thought maybe a short piece or large conduit. Any ideas? Don't say just to buy a kit because if I had wanted to go that route I would already have done it.

Just buy a stack kit LOL!

Paint the stack... well the stack will get VERY hot so it's probably more like powdercoat maybe?!

The flapper sounds cool and unique to these rigs since alot of the older big rigs have them.

G'luck in your endeavors and definitely get pictures up if you do it!

go to a semi grave yard and get a 5" or 6" stack off one of the semis and what ever else you need for pipeing

You will want to use something relatively thin. A piece of schd 40 conduit that diameter will be super heavy. For paint, go to advance and get some VHT 1200 degree spray paint. It works well. I used it on my turbine housing.

Go to the local Napa they can order alumanized steal of prefered diameter in 10' sections.

I aggree with going to a graveyard for semis and scrounging up a stack in the diameter you are wanting. I would not use conduit. As conduit last I check has a coating on it to prevent rusting. If I am correct on that your going to burn that coating off with a result of toxic fumes, kinda like welding galvanized pipe.

I say either buy a stack kit or scrounge one up at the graveyard.

According to the EPA toxic fumes will be coming out of it any way. You say Napa can order exhaust tubing in my prefered diameter. I'll have to check that out.

definately junk yard it. i got a whole stainless semi exhaust with muffler for 20 bucks at a place near me....alot cheaper than a stack kit.

You are correct the epa is correct also but the toxic fumes I am talking about are worse then what comes out now. When you heat up that conduit with the exhaust gasses, you will begin to burn off the coating on the conduit which will produce toxic fumes even worse then your exhaust gas.

u can use an old semis air intake pipe if its long enough... some of those old cab overs had them plenty long to use for a stack and they are about 7 inches.....i have one for a tip.. its a 7 inch one...... see if thats big enough for your truck
