Ideas any one??? I want a true dual exaust. Disconnect from behind the CATz use two mufflers and have the other pipe come out on the drivers side like the stock pipe on the right. THanks Eric

Depends on the kind of sound you want. There are sound clips on YouTube if you want to hear what different exhaust might sound like on your truck.

Be careful of the additional noise. I dont know if you are/were aware of the noise that duals would bring. Sure it sounds nice piping them for your friend but that loudness doesnt go away, say, on the highway.
I echo what Toxarch says about youtube vids. I actually posted one of my catback magnaflow system on my 05. Hope this helps.
