Made my own bell mouth adapters to bump the 2.5" air intake tubing up to the 3" required for the air filters. Just a 3" header reducer welded to a section of 3" exhaust pipe. Should be pretty good flow wise. These are just clamped for mock up. Later I welded everything solid. I'm using 2.5" fuel filler hose as couplers. It's much cheaper than silicone, rated to 20 psi, and much more rugged than silicone.
