There's nothing to void other than the second O2 sensors, unless maybe your engine blows and they can tie it into the engine running lean/rich due to the stock tune being thrown off by the HFC's. :dontknow:
 
berk doesnt have HFC's for the 2010 fx, which i have.

i was looking at this, which would be reaaal nice to get.

2009-2011 Infiniti FX35 Invidia High Flow Cat/Test Pipe (60mm)

its $730 and you know thats a rip. whats a good price to buy for HFC
 
Don't the HFCs cause your ride to give off extra emmissions? I heard if I put them on my car won't pass inspection in CA??
