My cat back system from jash @ c-red was around $1200, dump pipe was $180 and the front pipe was $150. The catback is japanese and was brand new, the dump pipe is made locally and new and the front pipe is a trust and was 2nd hand. Shop around and you should be able to get a good price, its the first mod you should do as the stock exhaust is very restrictive and only good for keeping the noise to a minimum
