DORMAN exhaust studs. Says it fits 4.6 and 5.4.

I need a set of studs, but why are they so inexpensive?

Dude they are just studs and nuts, how much did you think they would be?

Well I feel much like an idiot. I'm not sure what I looked up before, but I found a stud kit for like $70.

I usually use Advance Auto site to look up parts to give me an idea of cost because they have a good search engine. Now my search there comes up with $15 as well.

I have no idea what I looked up before.


So is Dorman a good brand? If not, what is?
