It all fits. Only fitment problem is on oil pan clearance with b16 headers, and in length of collector.

Spec R

People will say what they want, but that 2000 ITR USDM exhaust manifold did NOT bolt up to my head, even though everything else was a perfect fit. Ask anyone who's tried to fit a LS spec header on a b16 head, or vice versa. Until someone posts about it with personal experience, I will stand by my own personal experience.

Shoot, call up any company that makes Headers, and you'll find out the answer. Call up DC Sports or someone, Thork.
