Re: Headers or Manifolds
manifold top / header bottom
----------
manifold *usually* cast steel. stock factory. *usually* doesnt leak at the bolt flange. prone to poor exhaust gases flow. can crack. tucked close to the engine.
Header. *usually* tube construction. better flow / performance. prone to gasket blow out at flange due to heat and cooling.
