What kind of exhaust setup will benifit me most on my car? Just the exhaust, will do the extractors later on..

Or if you dont know, whats the most common setup people get with the xr6s?

Also, the costing of the exhaust systems if you know?

hey mate
i put a 2.5 inch manta system on my ute, pacemacker headers with a growler cold air induction
and i think the exhaust cost me around $400 off the top my head was about a year ago or so now
it gives a sweet note too
growler cold air cost me about $450
headers about $450 also
i got a Big Mouth CNC Billet Throttle Body to put on also put havent done it yet cost $380 put i have to swap over the gears and tps, just got to get around to doing it

but i think id rather go the headers first before the exhaust
