Naw, i get the manifold thing... plus they will never rust out, little chance of a leak and more pleasant to drive.. i got my headers for $100 and had no manifolds, easy choice :) I had my factory PS box in with my headers so a borgeson should fit.. I have my stock box still but 100k miles on it, and sat for 46 years.. plus i need LA brackets/pump and ****, hoping bergman can just send me a bolt in kit. I can do the box by pulling the torsion bad and not header.. not sure which would be more work honestly.
