From memory, it made about 25rwkw more on 1psi or so less boost and 35rwkw more with the same boost. Bolted up without a retune it made an extra 18rwkw.

Keep right off it until you get to your tuner. Link to comment Share on other sites More sharing options...

Is this too high for non fitted? Nizpro etc sell these for around the $2k mark don't they? Link to comment Share on other sites More sharing options...

Otherwise, spend the extra money on the Nizpro system now and save some money in the future. The only thing that would be stopping me from getting the Nizpro system is that I haven't heard much feedback about it. Plenty of people have used the XForce systems including myself. There is nothing wrong with them. They last, the cats do not fail early and the welds do not crack. They are thinner and lighter than other exhausts which means they can sound a bit tinnier, especially on startup, but they are also lighter. Yes they can and usually do have fitment issues but none that can't be sorted. That price sounds reasonable.

6BOOST Gold Donating Members 139 Member For: 16y 10m 8d Gender: Male Posted 17/11/09 10:51 AM Share Posted 17/11/09 10:51 AM Why is everyone going so big in the exhaust?? I'm not sure if the fpv's have a better exhaust, but my tornado with process west stage 1 cooler and ubp, 60lb injectors, hiflow cat and tune makes 314rwkw and backed it up with a 11.9@116.8mph first pass. I have no doubt it would happily make 350rwkw with the centre mufflers removed and an actuator to hold more than 10psi past 3000rpm. Bigger isn't always better, a combination of matched parts can yield good results for little money Cheers...............6BOOST Link to comment Share on other sites More sharing options...
