A few guys gave me an idea to increase the H box diameter to work better with my 3" intake setup. I didn't want to lose it in the first place, but seemed like a restriction/bottle-neck. I picked up an extra one at the JY and started experimenting. I think the end result will work more than adequate.
This is what the H box looks like sliced in half.
I got a piece of 3" OD exhaust pipe and cut it down to 5" long. Cut off the original tube ends and opened them up to accept the 3" pipe.
Pre-assembled to take measurements.
Measured out for placement of slot to coincide with the original one.
Positioned and a real good fit.
Mod vs stock.
Pic before I urethaned(windo-weld) the box back together.
