subaru Exhaust types, muffler only

My exhaust got a crack in it after going off a curb. yeah i deserved it. sounds terrible. but here is my problem. I want my old exhaust back.

its a impreza.. WRX 2005 STI

the dealer wants too much, 500 dollars for the exhaust. bascially what i want to know, which ebay item is the correct exhaust? muffler really.
just search subaru tailpipe on ebay.

JDM Subaru Impreza GC8 STi Exhaust System Tail Pipe

yes i know the item has ended but it has been relisted.

is this the correct muffler for my car? it seems a lil different, but i'm not sure.
