I have a similar question. I have a 2011 and got the 12589, but the guy at the muffler shop said it was 3" in/out while my pipes were 2.5" so it wouldnt work. Is this true, or did the guy not know what he was talking about?

The 12589

12589
DESCRIPTION: Inlet/Outlet Size: 3in.
Body Shape: 5in.x11in. Oval
Core Size: 3in.
Body Length: 22in.

It is true. Your pipes are 2.75.

However, you need a more competent shop, it can be made to fit.

They need to make reducers.

When i went to the place to get mine installed they ran out of that part number. I went with a 11249 which is slightly larger inlet and outlet at 3 inches but still was able to have it welded on.

How it sounds.

Is that a decent price, and the correct one?

i have none and im running the 5x11x28 and no resonator and turned down under the truck and I have a 6.2 not 5.3. You hear my exhaust for sure on the outside but on inside no drone at all.

A lot of folks here have the 12589. Sure they will chime in soon.
