luv my stack
I will submit my stack design
I built it as the turbo muffler design thats with the perferated inside tube open instead of closed letting the exhaust flow straight threw it but is interupted by the holes in the pipe letting exhaust threw . I don't know how many DB's but not bad as the tip is pointed away and up the pipe, made from 2in conduit ,1in conduit, freeze plugs
