Has any done there own stack kit?

 

Pretty much all but one stack setup I've built has been DIY. The kits are pretty reasonable though. What do you want to know?

 

how many 90 degree elbows would I need? I was thinking only one that would get to the bed and connect to a piece of flex pipe and that connecting into the exhaust. And the exhaust going into the 90 degree elbow.

 

Yes, for a single stack setup, you only need one 90*. Most guys doing a single stack are welding the stack to a plate and bolting it to the bed floor after cutting the hole. That plate should have about 3-4" of pipe sticking below the bed so you can connect it to the 90*. Does that make sense?

 

kinf of makes senses. How long do the legs of the 90* have to be?

 

Prolly 4" Are you ordering one, or do you have one? You can get them from airflo.com for about $90. Which is stupid high. If I was in a pinch, I'd order a stick of 4" exhaust tubing from jegs for $14 and do a few 22* cuts and make my own 90*.

 

yeah that is expensive. I do have a 3foot 4" stick. i'll try to make my own 90* elbow.

 

Whatever you do, don't just cut a 45* and weld a square 90*. Try your best to get at least one joint in between to help flow.

 

Where is the best place to buy stacks? looking for Mitre cut or straight cut.

 

you can try ebay, but my buddy had a problem with dents from shipping on his mitres . i got mine at a chrome shop near me and was guaranteed no dents. also guaranteed $140 each for my turnouts!!! good luck man

 

I got mine on ebay from the chrome shop people. They were packaged great, and showed up perfect.
