Hi-flow cat question

This is for any of you S197 drivers who have replaced your H-pipe with a catted X. If this has been asked before, I apologize. If you are running a Magnaflow catted Tru-X, a Bassani catted X, a Pypes catted X or a SLP catted X, have any of you gotten a CEL caused by the rear O2 sensors? I know the CEL can be turned off by turning off the rear O2 sensors with a tuner, but I'd like to know if anyone who is running the stock tune who hasn't turned off the rear sensors actually tripped the CEL. Bassani actually comes out and says their system will cause a CEL, because modern high flow cats cannot yet match the OBDII characteristics of the factory cats. Any feedback will be appreciated. Reason for question: trying to decide between a splice-in X-pipe or a catted X that bolts to the factory headers.

Re: Hi-flow cat question

I don't have an X pipe with hi-flows, but I have a prochamber with hi-flows. My CEL has never came on because of the cats. I know my brooksspeed tune leaves the 02 sensor on. I am not sure about my bama tune. If the O2 sensor is off, I will have to ask Doug to turn it on. I would spend the extra money and get the X-pipe that bolts to the factory headers.

Re: Hi-flow cat question

That's what I was thinking, too. I just hesitated when I read the blurb under Bassani's warranty page about aftermarket cats causing CELs. Do you know if the cats you got from MAC are metallic or ceramic substrate?

Re: Hi-flow cat question

I have the Magaflow Tru-X highflow x pipe. I had it on the car when I did not have the supercharger with the O2's turned on and did not have a problem with a CEL. Now, because of the SC, my rear O2's are off....

BTW I have the magna packs with it and the car sounds awsome...........

Re: Hi-flow cat question

Thanks to both of you. I like the Tru-X as well as the Bassani catted X. Since I'm running the Magnapaks as well, I'll probably end up going with the Magnaflow X.

Re: Hi-flow cat question

I'm no tree hugger, but I do try to obey the law. Besides, my car won't see the track; she's a street fighter. So, the cats will stay but they may be aftermarket ones.

Re: Hi-flow cat question

I don't about catted x vs o/r x with the magnapacks, but prochamber with hi-flow cats + magnapacks sound better than o/r prochamber + magnapacks. At least in my opinion.

Re: Hi-flow cat question

I'm sure it sounds good without cats, but I'm not going that route. What you do with your rides is your business. I'm getting a federal pension, so I'm not about to break federal law for the sake of a couple of HP and/or decibles. No offense to you all; that's just my choice. Thanks GMan; I'll give that some consideration.

Re: Hi-flow cat question

Whatever midpipe you get, stick with the hi-flows. When I had an O/R prochamber I dynoed an avg of 301 hp/ 303tq. With the hi-flows it increased to 304 hp/311 tq.
