installed the berk test pipe didn't get an CEL for about 500 miles then yesterday it comes on.....it has the "built in cel fix" if i add a spark plug non fouler will the prevent it from not coming back or is it useless to try? i reset the ecu once then the cel came back. i tried to pull the code to make sure it was the cat and nothing else with a Creader tool to pull it.....and it read no code - - - - with the check engine light on . so now i don't know what to do ....if i can't figure something out i'll take it to autozone to get the cel pulled or just put the stock one back on and see if get a cel still

 

I don't know what a "creader" tool is. Maybe it doesn't read OBD II.

This Berk pipe is poorly designed. The angle of the O2 sensor extension is pointed WRONG. It is feeding exhaust right at the sensor. The angle should be the complete opposite. Not a lot of thought went into this product as many people who have installed one have now reported CELs. You can try a non-fouler to extend the distance even further but it may still not be enough.
I guess it was a bad idea to try and save a few bucks over the T1R test pipe and a couple of non-foulers.

 

I've had it on for 2000 miles and never experienced a CEL...

Would suggest getting the code pulled with a real scanner to confirm that it is in fact the Berk setting a CEL. Seems like it would take longer than one day to come back if it took 500 miles initially.

 

I have a berk test pipe in my car and your points do make sense. Keep in mind I do not have any CEL's (yet), but when I bought it, I bought it only because I could not find out where to get any of the other test pipes at an online store. I did find numerous places with the Megan test pipe, but it looked kind of oddly shaped. Anyways, I guess my question is, what store carries the T1R pipe? If I ever do get a CEL and continue getting it, I wouldn't mind buying another test pipe. Thanks (btw, your avatar is very creepy).

 

I would guess that this thread would make it about the 4th or 5th person I've seen report a CEL with this thing since they got into the S2000 marketplace. It may very well be that the triggering of a CEL may purely be dependent upon the richness or leanness of the engine they are bolted to. I'm guessing that the cars that run a bit richer than most may be more susceptible to triggering a CEL with this pipe.

I got mine from BoomPlusToys. AJ Racing also carries them. I think both are board sponsors (or at least they were).

 

i have put about 1200 miles on the berk pipe and no cel yet
i have kn drop in and stock exhaust on my 04.

i had a megan one on my prelude and i had a L adapter for the o2 and had no issues for over 10k miles and going

 

they're was no picture on the website when i bought mine, but when i did get mine in i did notice the angle of the o2 sensor bung and that makes a very good point. but since berk tech claims it has a cel fix and numerous people are getting cel's shouldn't they do something about it even after i bolted it on and the "warranty" is voided from defects.

 

the creader scan tool does read obdII. should i write berk.

 

If you threw a CEL, a scanner should give you the code. If it didn't register a code with the CEL showing, something is wrong either with the reader or the ECU not retaining a hard code (if it was a "hard" code).
It's your prerogative as a customer to write to Berk if you feel it necessary.

 

Yup, I also got a CEL after about 5miles. Weird how some get it and some dont. My car is brand new so I doubt anything else could be wrong. How do you check the code on your ecu?
