Megan manifold came with the car. Actually I was waiting for it to crack when I first got the car so I can replace it but now 3 years later , still has no cracks! So I give them props for making a bad ass manifold!
s1 - for an evo9 turbo they perform very very well. I thought the s2’s were over kill.
fic 1450cc - i had no issues dialing them in. It was pretty easy on both 93octane and e85.
