About 5 months with the Stainless Steel adaptor, no issues yet. Got to see how it works in the winter.

Would this delete the code, or just turn off the light? Maybe a stupid question lol

I have a question even with the cat in the downpipe everyone is still getting the code?

Nick_Nasty's_GXP

That's because the high flow cat is just barely legal and the car cannot recognize that. I had the high flow cat in my 02 MCSS and the light still came on.

i thought the cat in the car stock was basiclly a high flow? Can you just tune the code out?

Yeah, you can just tune it out or clear it and use one of these contraptions, and hope it doesn't stop working.

It is, so if you keep the cat you might as well just keep the stocker.

ok thanks for the help we have emissions here and dont feel like changing out dp's to get it tested. (Wanted catless)

blakss

what if you just run a catless and tune it out.. and still have emissions ?what would happen there..

07carlocrusader

just turn it off,...

It depends on if they do visual testing also. Then you could just get a fake cat, which I plan on doing. Either this, or I am gonna gut my cat and put it on the Catless DP

depending where you live i just talked to someone here that does emissions and they compare cars now

I just replaced the catalytic convertor on my 2000 Pontiac Grand Prix with a Magna Flow model. It mounts the O2 sensor so it it REAL close to the floor boards. I tried to "massage" the floor with a hammer as mentioned earlier in this thread too. I wrapped a worm gear hose clamp around the drivers side rubber HD o-ring hanger to pull the pipe and sensor away from the tight spot. I was wondering if there is such a thing as a shorter sensor?? I saw a 90 degree adapter as shown...euro listing for $$ on Ebay. Is there a plug in anything that eliminates the need for the downstream sensor? That works?? That works w/o turning the SES light on? Appreciate any help!!

BTW, I wrote a little about this under my Grand Prix taillight help thread too.

Thanks

Yeah, that 90 degree fitting is available at http://www.bigdaddiesgarage.com/?gcl...FWV75QodumH8uQ. There are electric O2 sensor simulators too. Google it. O2simulator.com is one, there are lots of others as well as plenty of info on how to make one.

I have a 3in DP from ZZP installed on my Regal GS. I do not have a code and I passed emissions back in July. My entire exhaust was inspected from front to back. I was looking to get a DP for my Monte. Will I have these problems too?

I live in middle of NY State and my 07 SS has been inspected twice with the Hogan catted 3" down pipe with no problem and nothing ever said. As far as getting a code, I went 8 months without getting a code, I can only assume that perhaps there is some corrosion going on with the plain steel spark plug adaptor I used, perhaps the stainless steel ones would last a lot longer, I don't know. I now throw a code about once every 3-4 weeks. It only takes a second to clear it with my Cotex tuner, but I plan to slide under the car sometime and check it out.
