Repco, Audiobarn maybe? Supercheap, or an exhaust specialist, i got mine from Advanced Exhuasts, was just a chrome Tip, cost me 45 $, made it look pretty good, when i proprly get my exhaust done tommorrow, i'm getting a split tip from the exhaust shop for only 30 $ because there also doing my exhaust but the retail price for it was 80 $ But in my opinion Supercheap or an exhaust specialist would be the way to go :]
