agreed with the above. the roc-euro seems to make the most power and is the loudest. that might be a benefit or detriment. have heard concerns about their customer service though.
CTS like mentioned is about the same intake but better customer service, but they have had issues with the filter deterioration or rusting in relatively short time frames.
these styles are also some of the cheapest ones on the market.
I went with ECS for a noted power increase (not the most), a mild but noticeable noise increase, and a beautiful look. everything is a tradeoff. it's also a bit pricy, but not the most.
like grumpy noted, AZT did some logging with the stock box, stock box with holes drilled, holes drilled and an AFE filter, and then a large hole punched in the bottom of the box, and finally with the APR secondary pipe addedon. all added mild improvements in flow (which equals power), but very little noise increase and almost nothing for looks. choose your path.
