My prized EA S caught FIRE

Now she needs a few things replaced. Beside the obvious plastics, bonnet and such. I really should replace my whole exhaust system, my exhaust is 'torn' in several places and recently my cat got itself blocked, I drove around with it off for a while but then it caught fire. Loved the sound and the, even if slight, extra power (at least the illusion)

So in short: How much am I looking at spending for a whole system, and what about a hi-flo cat and extractors? Suggestions? Prices?

~$1000 for extractors (generic like genies) hi flo cat and 2.5" catback.
little bit more for pacies

I paid 300 for my cat back, got quoted 200 fitted for a highflow cat, but my car already had one, they can be had for under 200 off ebay, and my extractors cost 236 delivered brand new with gaskets off ebay. Mind you theyre no name ones but they are still 100% better than stock manifold.
