330 hp Stock Exhaust Manifold Swap
Is there any noticable increase in power from dumping the stock exhaust manifolds and I replacing with something like Gils or Stainless Marines? I don't want to do anything internally with these engines as next year I plan on pulling them, selling them complete and finding something with more power.

Other than a slight change in exhaust note, you'll notice little difference going to Gil or SM.
