Hey Lext,
I think Screeper and SBMike summed it up just fine. I added:
0-Corsa exhaust = decrease in MPG.
0-Headers = no change in MPG
0-Air raid intake = no change in MPG
0-Hypertech programmer = small improvement in MPG
0-Intake spacer = small improvement in MPG
0-Supercharger = HUGE increase in power and fun, but decrease in MPG.. (Worth the change in my opinion)
Enjoy your H2... they are AWESOME, and get used to being flipped off by granola eating, tofu farting ferries!!
