RA 2004 Rodeo Steinbauer Chip/Exhaust

I have a 3lt diesel RA Rodeo (non common rail) fitted with a Steinbauer power module. The improvement in power/torque was extremely good.
I am thinking of getting 2.75 inch Beaudesert exhaust to see if it will enhance the powe module a liile more.
Anyone got feedback on this, thanks
Cheers
Gary
