Minus the muffler?
Will I have enough backpressure to keep from eventually destroying my engine if I keep all four stock cats and run dual pipes without mufflers? I want to have 3" pipes dumped over the rear axle.

I have an 04 and left the cats and ran true duals out the back (No Muffler). Ive put bout 45,000 miles since ive had it done and it still runs great.

I'm running with no muffler right now...only thing I've really noticed is the gas needle moves a little more

You'll be fine. I'd run 2.5" if you're going with duals.
