Awesome mod review
These are tempting once I see a tune/manifold/high flow dyno. The loss versus a real header may be worth it for the easy life.
So I guess Afe dyno plot didnt lie and these can be compared to all the plots TheAxiom made. The bad news is that all those air intakes can't really claim 12-15 hp increases.
OP not to discourage you. BUt don't know if you will see a 250whp number after manifold plus tune. That is maybe real headers territory if I recall correct.
I predict something like 235-240whp based on intuition.
Which tune will you do: a off road header tune or a typical manifold only tune? Will a tuner like AA allow header tune on this? Because Header tunes differ than just turning off the CEL, wonder if the 300 CEL can handle it...
