That gives you the primary tubing and collector ends for a pair of fabricated headers. The two 9908S collectors have a four-into-one slip-on design with a scavenging spike, 2-inch inside-diameter inlets and 3-1\/2-inch outside-diameter outlets. The inlets slip over the matching primary tubes, ready for your fabricator to position them.\u003c\/p\u003e\u003ch2\u003eChoose the cylinder-head connection\u003c\/h2\u003e\u003cp\u003eTwo header flanges are purchased separately.
