as pirate said matt,your quote is excessive.the extractors from pacemakers were on when I bought the car however I have the receipt from previous owner and he paid 850 installed in victor harbor which was high in itself,the cats are still the original ones, the rest of the system is easy to install yourself if you have access to a hoist or are able to get underneath easily,i got my done by carline here in murray bridge and was able to help peter install the catbacks then the last section that goes over the diff,my rear muffler/resonator was deleted and just have straight through 2.5in pipes running through,these 2 sections are redback and cost 450 installed,so all up was 1400,the price depends on the system you get,whether it be a single system or twin system [one each side]lol
where abouts are you located in the city,lonsdale down south is probably the cheapest place to get it done
