DIY exhaust header with them 'looking good' and on the airplane?
First , this is the BOAT section . not airplanes . and also , there is a picture of his DIY header at the beginning of the thread . Not the presttiest , but it IS cheap and when you can't find one and have to scratch build one ... thats the info he gives .
Mysefl , not really sure I would want all that extra weight of copper or brass hanging all over , whereas for a boat , its not that critical to have that little bit of extra weight ( unless racing of course )
