Anyone been thrown a CEL with Berk HFC's?
 

Hey guys, just wondering if anyone has gotten a CEL using the Berk high flow cats. I got thrown my first one about 2000km after I put them in, I cleared the ecu and got one again about 300km after that.

I haven't actually checked the code yet (waiting for my OBDII reader to come from ebay) but hoping it's a catalyst code......

It's just that I haven't really heard anyone getting a CEL using these cats...

i have had berk test pipes on for 1,000 miles now with no CEL ....

Berk test pipes here too, and only got one CEL, and that was at Road Atlanta. Have done several more track events since and had no reoccurance.

I just had the HFCs installed and the installer commented on how long the "port" (not sure what it's called) that the O2 sensor connects to was, and how it's design was clearly intended to prevent such CEL's being thrown.

Not sure if he was BS'ing or not and I only have ~50 miles on them so far, so I'm obviously not going to have a CEL this early.

Yeah they are made really long to push the O2 sensors further out of the direct air flow to prevent the CELs, thats why i wasn't expecting a CEL.... :( lol

Is it too late to disconnect the o2 sensor and put in some steel wool like others have done?

Nah it's never too late, pretty simple job really I guess i just need to make sure thats what is causing the CEL though... pretty strange that I seem to be the first though :(

5000 miles on mine, not a single CEL.

my friend randomly gets them on his G37 with FI cats.

anyone want to trade their test pipes for my hfc's?

im sure you can get someone to buy you a new set... the pita of the install and or $$ to do so will be a hassle but Im sure if you posted this in the Classified section someone would buy you a new set of Test Pipes for your HFC...

i love the sound of my stock exhaust with test pipes 90% of the time, when its cold around 3-4k the rasp is a bit annoying but nothing too bad.. im sure its there with hfcs to an extent.. This was the same with my old g35 coupe but once i got the greddy exhaust it just sounded brilliant as im guessing it will when i pickup the FI or Stillen in due time.

sorry to go off topic in your thread though... btw youll love the car , was the 300 a tt ?

Forgive the noob question, as I'm just starting to read about exhaust systems, but why would you use test pipes? Doesn't that guarantee a fail in emission testing, or do you just swap them out for the stock cat when you test?

Some states, such as Georgia (where I live), have zero emissions tests or inspections.

So for less money, you can achieve better flow, gains, and sound, albeit too loud or "raspy" for some.

2k on Berk's HFC's and no CEL's so far.

3k on Berk and couple hundred on my exhausts, no CEL.
