look in the forsale section on here dude, i bought a kakimoto catback and a custom made stainless dump/front pipe (turbo back) all up was... 740 including postage (40 bucks for catback, 0 for turbo back)
its an excellent exhaust btw, its very quiet from 0-4000rpm, after that its a pretty decent roar. quiet exhausts are very good for not getting defected. when you get rbt'd or pulled over by cops and the there engine is louder then your whole car they tend to not car about anything, i mean, i got HID head lights, had a very loud pod, black wheels on a silver car (the wheels face, not rim, pokes out guards) and i never have any issues .
your car looks excellent mate! i bought mine stock 1 year and 1 month ago, youll love it!!
