It gives you 1-7\/8-inch primary tubing with a 3-inch outlet, useful dimensions to settle before the connecting exhaust is made. The two 9905S collectors have a four-into-one slip-on design with a scavenging spike, 1-7\/8-inch inside-diameter inlets and 3-inch outside-diameter outlets. The inlets slip over the matching primary tubes, ready for your fabricator to position them. The twelve JB-188-25-16-304 J-bends are 16-gauge, mandrel-bent 180-degree tubing with a 2.50-inch centreline radius.\u003c\/p\u003e\u003ch2\u003eChoose the head flanges separately\u003c\/h2\u003e\u003cp\u003eTwo flanges are required for your cylinder heads.
