Bought a Z for my wife and we both agree stock exhaust and intake could use improvement. I've experimented a bit w/ my C5 weekend driver and know how CAI and the right CBEs w/ HFCs can increase HP after a tune. Anyway, I have the following questions on my 2 choices for intake and exhaust mods:
1) HPS hoses w/ K&N drop ins or RC2 CAI, is the RC2 any better? I would go with the G3, but want to stay close to a stock configuraiton so no worries about air filter changes and water.
2) Invidia Gemina CBE, does the system include the HFC? Is it a good bang for the buck? Also, it appears from the wave clips that there is no drone and little rasp, is this correct?
Thanks for your comments.
