Exhaust manifold for a 2.2 ecotec
I own a 2009 HHR 2.2 ecotec, on the HHR forum I read that the stock exhaust manifold from a 2.0SS or 2.4 is a better manifold then the 2.2, is this correct, if so do I need a DP with the stock 2.0SS manifold.
Is it worth the change to get the extra HP, or is there a better solution with spending to much.
Thanks
