I too felt that the Touring was way too loud. I didn't really mind the noise outside but it was just too loud in the cab. This is the quietest vehicle I have ever owned, not any more!
I had seen several posts saying the Borla resonator didn't quiet it enough, and it is way expensive for basically a small (5 x 10??) glasspack at over $200. I decided to just put a 6 x 14 round magnaflow muffler (#12619) in place of the factory front resonator and I am pretty happy with it. It definitely took it down a notch, I would still call it aggressive but no longer obnoxious.
$100 plus a couple clamps, can't beat that! Only downside is its 409 stainless, but so are the factory pipes up front.
