Ohhhhh I LOVE these posts... exactly the same thing happened to me on my 04. Same place, commonly breaks there! Best option I could ever recommend is do what I did, and get an Invidia Gemini true dual cat-back system. Not cheap (around £850) but so so so worth it! Not too loud, but lets out a lovely growl when you open the taps!
This is mine when I first had the exhaust installed
