do aar cuda downs fit a duster

downs is the term my local muffler shop called them

wow what an out of touch redneck shop:violent1: what do they call a muffler? a muff? a tailpipe? tail?

used formally in a redneck sentence: "hey can you put some downs on my car also I think the muffs are leaking and could you check the tail why your under there" :banghead:
