Popular Exhaust Mods?

I'm wondering what popular Exhaust mods are being done with these rigs. Are people removing the stock setup in favor of a true dual exhaust with new manifolds and different mufflers. What size is popular? I'm assuming 3" per side would provide plenty of air flow...

It seems that the most popular exhaust for these trucks is a MBRP 4" cat-back or turbo-back system.

4" single is most popular.
You can also buy a 5" exhaust too.
Duals are really just for looks.

mbrp downpipe back no cat duals. I didn't like the fit of driver side pipe so I drilled a new hole further forward on frame. Then that pipe was higher than pass. side so put a new exaust hanger on that side. You don't have anything listed in you're signature but I'm assuming that you got a Dmax and are looking for exaust?
