yeah i should have noticed said he said twin scroll, that he had an s4 mani :redface: but i still have 2 ahahha! have u guys ever seen those cheap custom manifolds on ebay? i want to try one out... fully divided.....

hey banzai i think you want to keep the divider in there, look at the s5 setup its divided all the way from the ports

I hope that divider isn't too thin. It could crack from all the heat being transfered right there, I guess you will find out though.......hehehe I think switching to 25 mani and turbo is the best......if you happen to have that **** laying around https://www.nopistons.com/forums/pub...#>/biggrin.png

Don't have a S5, If this cracks I'll weld up a new manifold
