Do you guys have issue with CEL? If so, after how long of the installation did the CEL come on? What did you do with the issue?

 

I think that Stillen should take back all the Hfc that they sold, The reason most G owners are willing to spend so much is to avoid the cel. It defeats the purpose of paying so much for a Hfc if the cel still comes on, might as well just go to a muffler shop and do a straight pipe for $85-125 instead of paying $600+. I was considering hfc for my car but was very skeptical about the cel. for obd1 cars its not an issue but for any 0bd2 cars, its a real pain. Just my opinion

 

^^ If I knew Stillen will also have CEL issue... I wouldnt have bought it too...

 

I bought straight pipes from Ichiba for that same reason, almost everyone that has hfc's has thrown a light

 

i got cel on fi hfc but tony from fi took care off it! ++ tony and fi customer service

 

^^ tony said some ppl still got CEL (after non-fouler) So he told me to wait because hes trying something else.

 

In the name of performance the 10-12whp you gain from HFC's is tough to beat. HFC's make more power than all of the $1400+ exhausts.

For those of you with STOCK cats, ~98% of you will be CEL free. Those of you with HFC's, ~95% of you will be CEL free.

The only 100% way to avoid a P0420 & P0430 CEL is an electronic O2 simulator. However, nobody will make these anymore because they are highly illegal. The EPA fined Casper electronics $125,000 for the sale and manufacture of these devices in the late 90's. That's enough to scare anyone away.

 

^^^ wow look a reasonable and mature post.

 

 

 

So pretty much there is no option to get rid of CEL w.o. o2 simulator? because non fouler did not make 100% get rid of CEL...

 

i was thinking about getting the FI HFC, does that mean it will throw a code light also?

 

well i know for a older way to do it is make your own with resistors, i have no clue how but there used to be websites on how to make em...

cel eliminator is what its called

 

IMO most likely? Positive side is whp gain

I think I saw it at the G35Driver

 

wow that is sad to buy a hfc with a cel.
