1.2-1.5cf tuned in the mid to upper 30s. Round ports are easy to calculate and work with, use either a 4 or 6 inch port. You can get a 2ft section of 6in sch35 pvc at Home Depot for about $9. The ID is about 5.875, OD is about 6.125. If you need to bend it, use a sch35 90deg elbow which is usually under $10 at Menards.
