It's a good performance car but I would also look at the Mazdaspeed 3, Cobalt SS (turbocharged) and some other competitiors.































For normally aspirated cars with small engines, intake, exhaust and a tune (chip) will give some modest performance gains. Headers will cause complications with the catalytic converter and won't give a huge gain.































If you look at turbocharged cars, upping the boost on the stock turbo will give a much larger performance benefit.
