I would be worried about the firebox pipe, I honestly don't think you will get much heat through there for that chamber.

But as far as the stack goes, I always suggest to folks to drop it an inch or two if coming from the top, you can always use an adjustable piece of flashing inside if you want to drop it further.

Also 4" seems small can you go 5"?

Wait for Ribwhizzard to chime in, the man knows his stuff!

I don't think you will get any draw through that pipe, sorry to seem negative, but you may need to make some changes.

The inlet from FB-CC seems small to me and i dont know itll draft correctly.

For the exhaust stack ive always tended to have a better when the stack is flush with inside when mounting to the top or back. When mounting on the side i always build an angled box for it and in my cases it helpw with draft cause its not having to make a 90 degree turn from inside pit to up the stack.

Ok thanks. I'll have to measure when I get home. Don't worry about the negativity I've just kind of been throwing this together with stuff laying around the house and winging it lol

We're here to help and im all about people stepping outside the box with their builds. It makes it their own ya know. But with dimensions we can get you some solid numbers to go off of.

Would 4" pipe be good for my stack size also?
from the looks of your chamber I wiould go 5", but before you go any further, have you referred to the pit calculator?  There's a link in my signature, I would do your calculations and post them here for some advice before you go any further, more pics too, especially of that firebox.

You got me lost on the last part of your post. CrazyQ. You talking about length of cooking chamber? Bc thats about 56" between the caps?

Id definitly go with at least a 5" stack but probably would step up to a 6".
