HP Manifolds

No matter what you do, the exhaust is likely to be fairly expensive. Let's start with HP manifolds. 68-69 (the better looking of the bunch) B-body HP sets are worth $250 or more. Head pipes will probably cost $100.side. So, at least $450 for something that fits ok or $750-ish for headers (yeah, $300 is $300, but for what it costs to build a car...). The rest of the exhaust if the same.
