i say go with HFCs!

 

i hear the FIHFC does not throw a CEL, but how about the art pipes?

 

If I was definitely staying with the stock exhaust and given my experience with the excessibe quietness of the FI Resonated HFC (no experience with just HFC), I would choose the art pipes for better sound and performance.

 

I had FI RHFC's and loved them. Best IMO No cell and the sound and lowend and mid-range was NICE

 

FI's resonated cats are awesome, had them now for 2 years and sounds great. The first couple months they sound raspy, but that goes away with time.

 

art pipes do not throw a cel either

 

for everyone with the F1 HFC's and a model year 2012+ has your car thrown a CEL?
