Well, I think I need a new Exhaust

Driving to work one day this week the EB started making a shit sounding rattle when I was letting out the clutch at the lights, but didn't seem to do it when I wasn't putting load on the engine/gearbox so I'm thinking "shit, screwed bearing or something (i was thinking it was the thrust bearing)" but as it got worse over the next 2 days it began happening whenever the engine was revved, so I decided the cat had probably collapsed.
Then in the space of about 40 km's on suburban/freeway roads my car went from normal std. sounding exhaust to sounding like a truck, so this morning I crawled underneath to see what was going on and this is what I found:



The hole in the muffler is almost big enough to fit a tennis ball inside, and the cracks from the hole go right across the surface of the muffler! The shit thing is I haven't hit anything in the last few weeks, so I have no idea why it happened!
Its so loud that I don't bother putting the stereo on anymore (thinking about wearing earplugs while I'm driving till its fixed, its farkn loud!) and the vibration thru the floor made my feet go numb on the freeway coming home last night!
Oh well, looks like I'll finally get that 2.5 inch system on it!
