Will new muffler help with fuel efficiency ?
The muffler on my 2007 2dr HB is getting pretty rusty, I think the whole exhaust system is stock, so about 10 years of age. I'm planning on giving it at least a new muffler in the spring, and I'm wondering if an aging muffler does any significant loss in mileage ? It's not perforated or falling appart yet tho, just very rusty.

No, buy a new right foot instead.
Buy your muffler based on the sound you want, otherwise just do oem.

Scraping off the loose rust and scale rust and debris on top of the muffler will extend life, as all that holds water and salt.

I also have that clinging noise that I remember someone mentioned was caused by a loose piece of sheet metal banging against the manifold or exhaust pipes around the back of the engine bay, that would be the next fix I want to do. Anyone has a clue on the most probable location of the loose sheet metal part ?

Clanging could also be caused by a worn out gasket between the manifold and the down pipe. If your '07 is still on original gasket, then it is probably shot.
