Newbomb Turk

I’ve been thinking about upgrading the exhaust on my new (to me) 2007 King Ranch 4x4 because, hey, a truck should sound like a truck. I don't want anything too loud, just a deep, mellow tone. Based on information that I have read on this board, it appears the exhaust has very little impact on these trucks other than sound. With this in mind, I think I will just swap out the muffler and maybe add a tip.

I was going to install the Magnaflow catback system (16518) because I liked the sound Youtube. Does anyone know what the part number is for the Magnaflow muffler that is included in that system?

I am considering Magnaflow or a Dynomax Ultra Flo Welded. Any opinions or recommendations?

Thanks!
