You mean dyno numbers? No I don't. The G3 intake has been shown to have the best gains of all the intakes out there, though mostly at the upper RPM range. HFC's free up the restriction, so will have added benefit, no matter which brand you buy. As for exhaust, I had a set of Invidia on another vehicle. The welds and finish around the flanges are great. Plus the exhaust isn't excessively loud. That's why I chose that combo. I think you'll like it too. Make sure you tighten the O2 bung caps on the HFCs after install otherwise they'll rattle and loosen.
