exhaust, downpipe back?

[lteeone]

What are you guys using for exhaust after the downpipe? or are you. I currently run a single 4" with a dynomax welded round muffler that dumps just after the pass seat. but would kind like to do dual 3.5 to the rear axles.

thanks

I'm running the Torque Tech 3 in dual system over the axles.
