My Engine Bay Transformation..UPDATE June.8th!!!

[Brett Haviland]

meh that 2G or evo manifold you have there is EASILY good for 400-500 HP.

Spend your money on upgrading other stuff before you shell out for a FP manifold, like a turbo, or injectors/fuel system... so much other stuff that will be better then buying a new exhuast mani.

I agree, port that one if you like, and ceramic coat it. 

The FP manifold does make a difference, I had a before and after with no other mods, but a well ported 2g is just fine and the heat shields fit well.
