650 gets the basic ces dump pipe. full description appears earlier in this thread.
that's the rrp. the company is located in qld. sabbadin is the local agent and the manufacturers do not want to undercut robert at sabbadin. it's so expensive, according to them, because a LOT of work goes into them. they claim that no other dump pipe manufactured in australia can reap the same gains.
i guess i could check ebay for internationally constructed gtir pipes, however there would be no way someone with as little expertise in this area as me could tell which ones are guns or duds, unless someone had a comparison chart of all possible pipes and output figures. i have to take peoples word. in general, i tend to believe that you get what you pay for, and i just hope this company is not greedy when it comes to mark-up.
when it comes to a job like this, i want the best, straight away.
