As you get into that quality & price I think I would go with Mark Leelchock of Performance welding in Forstell Ca. He is by far the BEST when it comes to SBM or any Mopar for that matter !
Not sure about that. ARH has an outstanding rep.
they make every header on Copo, Drag pack and the Cobra Jet.
everybody I have talked to who has stuff they have done is super happy.
