Exclamation JBA Hi-Flow Cats / Midpipes CEL

Strangely enough I just got a CEL on my otherwise stock SS---~500 or so miles after installing the JBA midpipes.

P0430 - Catalyst efficiency below threshold (bank 2)
- Looks like it threw the same code twice at the same time (if possible?)

Now I don't know what to do.

1. Go through the hassle of putting the stockers back on; and lose all of the sound (which kicks ass), and the performance (which was a BIG gain).
2. Get a tune. Which means I lose my warranty which I really need because I want them to fix my piss-poor clutch and horrible rear diff noise (low speed turns).
3. Ignore the light / reset it every Xxxmiles. (Warranty questionable)

Input? No one else having this problem yet? I bought these cats thinking that several members had more miles than this with no CEL.

Thanks

had mine on for over 1,200 with plenty of hard accelerations. Also had borla s type and c.a.I. No tune, no CEL yet. Sounds meaner than ever, ordering jba shortys in a week. I'll report to the forums how that goes.

See that's what is driving me crazy. I can't find ANYONE with this problem so far. What the heck?


1. Is it possible that I installed them improperly?
2. Could it be a defective set?
3. Are California-purchased Camaros different in any way regarding emissions, ECM programming, etc.? I hate CA btw...
4. My car was purchased at the end of August 2009, so i guess it is fairly early number car. Are there any ECM updates that a dealer could do? (semi-unrelated question) My dealership really sucks and no one there knows anything about anything. Like really worthless.




A couple of other unrelated notes:
a. buyjba.com is great. I ordered from them on a Friday late at night thinking they would take a week to get to me. I get a call on Sunday from them saying that they are local and would drop them off I'd like. Great service, awesome price.

b. I am going to try to contact JBA tommorow. I think they are somewhere here in California. I will also say I was somewhat concerned when I saw that the box said made in mexico, because I was under the impression that they were manufactured here in California. My midpipes had pretty bad burrs in the I.D. of the flanges, and the back o2 sensor bung locations puts the o2 sensors VERY close to the transmission. So I'm not sure I'm really thrilled with the fit and finish-related quality of the product.

Seriously any input would be great.

Most likely number 1, try maybe taking a look under the car to see that everything on right

I'm going to take a look this weekend. It was pretty straightforward however. The only think I was worried about AT ALL was that the exhaust manifold-to-midpipe connection could possibly leak due to: a) somewhat questionable fit and b) their crap nut-and-bolt design on the flanges. Man was that a pain in the ASS! Why couldn't they just put a stud on there? I know this has been observed by others on here....

So then do you think that if lets say that connection has a little leak (which I have no evidence at this time that it does) that could cause the code I have? i.e. cat efficiency below threshold?

edit: I put a small amount of nickel anti-seize in all the bosses for the o2's. I suppose there is the possibility of a minuscule amount of that stuff getting on to the actual sniffer part of the sensor, although I consciously and actively tried to avoid that from happening.

I've had my JBA midpipes on probably the longest of anyone on this site. I have never popped any CEL codes. I agree that the fitment is not that great with these pipes. I too noticed that they were made in Mexico. I also worried that the driver's side midpipe would not seal at the coupler clamp because it was shorter than the stock pipe (I just split the difference with the clamp).

In addition, one thing I never mentioned in my original thread is that I had huge hanging chads inside the O2 sensor bung-holes (sorry I'm laughing as I write that ) when I first got the pipes. These chads were due to the drilling of the pipe to put the bung in. I managed to wiggle them back and forth in the bung-hole with my pinky until they broke off.

Anyway...I ditched the grade 5 crap hardware that came with the midpipes and went out and bought some grade 8 flange head bolts, nuts and washers at the hardware store. I've never had a leak.

I'm thinking you may have a leak somewhere causing the code. As long as you put the nickel anti-seize on the threads of the bung-hole or sensor and not on the O2 sensor itself, you should be fine. I used nickel anti-seize too.

My JBA threw a code with in 50 miles...i emailed JBA and they DO have great service...ended up having to take them off and sell them on here...I had a different code though...my electric cut outs are right near the rear O2 sensor...the extra flow from the JBAs and the extra O2 it was reading from the cut outs were causing it to throw the lean code. But JBA got back to me through E Mail on a Saturday within an hour giving me ideas of what it could be and even looking up a certified or known JBA installer in the NJ area, so A+ for them on their half!!

I would clear the code and see if it comes back. I had a CEL when I first put them on as I did not disconnect the battery when I installed. Never had a cell after that for 2500 miles.

I have around 600 miles on my JBA and no issue with a CEL coming up.

First.....
I love JBA!!! The shortys and the 3" cat back are unbelieveable.....but...
I think the Solo Cats are built better...02 placement is like stock....
and made in Buffalo NY....only reason I did not do JBA Cats...

Or...save even more money and go down to Autozone and buy a spark plug anti-fouler and use it instead.

Same here no codes with my High Flow Cats and I also have Noweeds Diverters and no Tune. The fitment is horrible tho but in your case i think you should put back on the stock cats and see what happens.

+1. Im not from New York but it is worth the extra money to support a company that makes their products in the USA.

I also believe in the buying U.S. but companies can have parts manufactured in other countries and just do a small percentage of work in the United States, and not have to say it was made outside of the U.S. "Many due this"

You cannot be totally sure what is REALLY built in the United States.

Just my o2

No sh*t right? The pipe used by Solo and JBA is probably made in China.

The way I look at it is we buy things every day that are made out of the country so why would car parts matter.

Big three builds in Mexico and lots of the parts on new American cars are made down there also. This keeps the price of a new car at $35-40K instead of 45-50K.

Thanks for info all.

I'm going to put the car up on the lift tommorow and double check that all the t's are crossed and i's dotted.

I just got off the phone with JBA and they were very helpful and seemed committed to helping me. They agreed that it is possible that I have a set of defective midpipes and that those particular units might not be catalyzing as well as they should. They recommended that I clear the codes (which I did), and do a full battery disconnect/fuse pull (which I did NOT do at time of install) and give it a few weeks. If it comes on again they said they would agree to look at the cats and do an exchange. He also mentioned that he thought anti-seize could possibly affect the grounding of the o2 sensor () and to double check connections and voltages.



Again thanks to all.

btw....it would be nice to live in the age where you could buy everything US made if you wanted too. Sadly it is no longer. I cant remember the exact number but our cars have very high percentages of foreign sourced parts. I ALWAYS look at where ANYTHING I buy is made, and weigh that against price and all other considerations. Frankly however, I believe in basic economic principles and in keeping costs down. The exception is that when given the choice, I WILL NOT buy chinese, even if I have to pay WAY more.

I agree...I don't mind Mexico as I go there and enjoy their resorts and
booze. China already owns the US so they don't need any more of
our money.
