I have part #'s in the garage, give me a few minutes and I'll post it. I tried Walker 31400 first, they were not up to the task at all. Didn't take long to blow them out. These Few-Pro units are much better.

Ok, here ya go

Thanks. Do I need the studs and nuts too?

I'd soak them good with penetrating fluid and let it soak overnight. Can Tire carries PB Blaster or Sea Foam Deep Creep. Don't waste your time with WD40. Dodge dealership sells an excellent penetrating fluid too. If you end up needing new hardware you should be able to buy it from any of your local muffler shops, Carquest or Napa.

Stainless studs and stainless or brass nuts and coating them with anti-seize for the next time is the way to go.
Some have a 5/8 inch hex and some have 11/16 in hex. Deep well socket is your friend.

Usually when you "smell exhaust" and you're neither standing behind the car or have a Camaro parked in front of you, it's because you have a bad hood-to-cowl seal or negative pressure inside the cabin is pulling in air through gaps in the rear body, such as around bumper bolts, bad trunk lid weatherstrip seal, missing body plugs in trunk drops, etc. Bad exhaust donuts will usually manifest themselves with a "pffft-pffft" noise as well.

You don't NEED stainless studs but you should use brass nuts. You should be able to get them at any parts store.
