Sports Cats Falling Apart or CELs??
I'm considering adding AWE sports cats to my setup, primarily to amplify the exhaust sound, but also for the performance boost. I just spoke with one of the most reputable aftermarket mod dealers (who sells my ECU tune) to ask if the ECU should be re-tuned after adding the sports cats (he said no). What is troubling, though, is that he also said that he doesn't selll any sports cats because they throw CELs and fail over time -- he cited two examples from a few years ago where he had to repair sports cats that "fell apart." This shop sells nearly every other performance mod but the sports cats, and has a strong rep on this board, so I ask...
HAS ANYONE HAD BAD EXPERIENCES WITH AWE CATS (or other sports cats) IN TERMS OF EITHER CELs, THEIR FALLLING APART, OR ANYTHING ELSE I SHOULD BE AWARE OF?
I've read the past threads on CEL problems with the AWEs, but its hard to tell if those were due to installation errors. I'd hate to install them and start dealing with headaches, especially if there are other less troublesome routes to take -- e.g., headers, intake. I was surprised to hear the negative feedback, given the general enthusiasm for the sports cats in this forum. Thanks.

yes, I have had both CEL and a rattle coming from my AWE Cats. I tried a few things to get rid of the CEL, and in the end the Softronic Flash got rid of them by changing the parameters of air flow from the first to second O2 sensor.
The rattle is just something I am living with for now. I plan to redo my exhaust in the spring.

I have had my AWE 200 cell cats on my car for about 7,000 miles. I haven't had any issues yet and I bought them used on this forum. I don't have a rattle or anything at all and I'm very picky. I had them professionally installed, so maybe that is one reason for my positive experience.

Checkout the Fabspeed ones... We do alot of those. If you put anytime of high flow cat on your car, it may trigger a CEL. Softronic raises the O2 limits so you will not have any CEL from this.

I just had AWE 200s professionally installed. They at least look really nice! No rattles or CELs though not many miles on them (yet).

It's no secret that we had some problems with our first generation of cat sections made years ago. At that time the HJS cats we use now were not available. We were initially using the best cat that we could find.
The new HJS units are the norm and used by mostly all of the better aftermarket exhaust manufacturers. If you want to know what kind of cat you have from AWE, look for a stamping that says HJS. If it says it, you are in the clear and have the good stuff.
Also, if your car is in good health and the rear O2 sensors are in good shape then no special software is needed to keep the CEL off. These cats will pass an OBD2 sniff test.
Now, what we have seen are cars that have running problems, certain questionable modifications, or software that cause the car to run rich. Over time an overly rich running condition will cause any cat to break apart and fail. We cannot be held responsible for that and would deny a warranty claim if we got a cat back for inspection and it wreaked of gas. Trust me...it's happened.
Also, even a set of stock cats can fail prematurely on cars that are used very often at the track. Extended high EGT's can do some damge!
If you have a first generation set of cat sections, and they have failed, please contact me directly. While I can't comp a new set of HJS cats sections, we can certainly offer you an incentive on a new set to make sure you are a happy AWE client.
Hope that clears the air.
Happy Holidays to All!

I would have like to have tried to help.

I do have the first gen cats, and I do track a lot. I have also killed a one of my PSE mufflers. Not bad for 24,000 miles!
