This is a 1.8 manifold with a ceramic coating, tapped for EGT on each cylinder, resurfaced on both flanges, set screws for each 10mm stud. The DP is stainless steel, the swage does not leak, and its 2.75" at the rear flange. I'm not sure if the rear flange will bolt up perfectly or not...but it bolted up fine on my Enthuza exhaust.
Buy this and Trackspeed inconel studs if you want a track reliable set-up with studs that won't stretch.
$500 buys both
