So I'm exploring my options as to upgrading my intake manifold. One option is going with skunk2's manifold but I know for a fact with that throttle body my car isn't passing smog. One option I've seen is going with a tsx manifold and bolting it onto my accord. Both k24's and from what I've seen, the install is fairly smooth making a considerable difference in performance. I'm new to building honda's and if anyone has any info on this topic could you please slap me with some knowledge.

My car: 2005 honda accord ex 2.4l. Intake, headers, exhaust, ecu
