Personally intake or exhaust won't get much out of this car. 10 whp at tops. Again those are top-end power. You will probably loose some torque at the low end with just I/E. so tuning is a must if you are looking for "true" gain

This. The dyno chart shown earlier in the thread clearly indentified the pro's of a simple tune. Exhaust restriction from the factory, due to emission regulations, increases back pressure in the EGR system to cool down high compression chambers to reduce NOx. By opening up the exhaust and properly tuning the ECU you should notice an improvment in acceleration. Hopefully the magnitude of negitve slope on the torque band can be decreased so it will be as close to zero as possible. Btw when you tune the ride do not use a piggyback.
