H-pipe will give it a deeper sound, X-pipes sound similar to a 2-into-1 exhaust. Both help it sounds "better".

OP, I would suggest 18" bodies if you don't want it super loud. 2.5" exhaust pipe would be plenty, and I would go with an H or X after the transmission/xfer case. Skip the Magnaflow premium, and buy Jones/AP/Cherry Bomb copies. The 5x8x24 would be a great option as well, that would keep it super quiet until you smashed the go pedal.

If you end up with drone, you can use Helmholtz resonators on the tailpipes. @aknovaman, has done some write-ups on it, great guy and very helpful!
