HFC question
 

Will ark HFC have any trouble with warranty? should i keep stock just in case?
i hate stocking stuff..

i actually left my stock exhaust with the mechanic..
also gonna do the same with my intakes and HFC stocks if i wouldnt need it
for warranty purposes..

The dealer will probably tell you yes, searching warranty hfc on google should produce the appropriate reading and answer you are looking for.

Cbe and intakes won't.

I would keep them. I work for a different car line and when it comes down to anything engine related for warranty they will want to see the stock ones on.

FYI, HFCs are illegal in CA and will not pass the CA smog inspection.

my local dealer services my car with Berk hfc and catback, idk about anywhere else though. don't ask don't tell is my policy.

As part of a CA smog test, the inspector is supposed to inspect the catalytic converters to confirm that they have not been modified or replaced.

With that said, if the inspector does not recognize the HFC as a modification and your car passes the sniff test, then you're good to go. It's simply a matter of buyer beware.

I actually threw a code (P0152) and thought I was screwed for warranty purposes since I had Berk HFCs installed, but they replaced the O2 sensor no questions asked :D. I can only assume because it was failure in the exhaust manifold before the cats, but I think I just lucked out with my dealership. For the most part, good idea to keep stock parts

always keep em just incase but hfc send no check or service engine light if installed properly so u should be fine

I don't think there is any denial of service for having HFC's. So I wouldn't worry about getting some standard maintenance done.
