MAP's Evo 8 & 9 Exhaust Manifold Testing / Dyno Results
I was a fan of these results as well, since it was tested with my car!
The manifold is a really excellent peice, very well made. I used to have an ebay mani on the car, and this new manifold removed a lot of the "tick" you would hear from the metal being so thin on the other manifold.
The flange and portwork to the runners is INSANE. It was so smooth and so shiney I swear I could almost see my reflection in the INSIDE of the runner where you would usually see messy welds. On the street it feels super solid as well. The spool is both quick and smooth, and you can feel the gain and consistency in the mid-high range. (especially when we turned it up to ~35 psi after the testing was done)
Overall I'm more impressed then I thought I was going to be. I am in no way affiliated with MAP besides being an occasional customer throught the last 4-5 years. I would say this manifold is worth every penny, and then some.
Edit: Forgot to add specs of the car
Built 2.0 (Manley/Manley) GSC S3 cams, +1mm valves, stage 5 head porting, e85, FP Black, STOCK intake mani/throttle body (soon to change), etc. When I was originally tuned it was for around 39-40 psi, but since then I have turned it down for winter.

Seeing this, I feel like Flava Flav screaming, "Yeah boi...!"
How much would a polished long runner manifold with the MAP stud nut kit be shipped to 85650?
