I am thinking of getting extractors fitted to my car. I want to know from the guys who have got them on thier car if they are worth it. How much better does it sound? How much did they cost? Was there any performance benifits in doing so. I would expect around 10kw would be gained by fitting good extractors. Also how much did your insurance go up? I would hate to have to pay heaps more on top of paying fully comp and then paying for for the mags I'll be getting.
1999 AU XR8

152.2RWKW (APS dyno)
Switchable Shift Kit, K&N panel filter, Lukey straight thru mufflers, momo gear and steer,
DBA slotted rotors/Bendix ultimate pads (front), Pioneer MP3 head unit and BA XR carpet mats.
I went through SVO in Ringwood for mine about 6 months ago they are a set of HM stainless headers and 2 1/2 inch mandrel bent system basicaly the same as everyone recomends as a sports system. High flow cat and all the other usual stuff.
I noticed a good pickup in top end power from about 3,00 rpm up it revs a lot more freely and pulls all the way to about 5,300 rpm.
According to the fuel pump and the trip computer fuel econ is better by about 1 litre per 100 k's town travel (Melb)
The system sounds nice in my opinion a lot deeper than the standard six but mine is not overly loud. You can get your system set up for noise if that is your thing. Anyway that was $1,200 fitted but mild steel will be cheaper by about $300 I think.
