So I decided to go for the tune, I'm leaning toward EPL to do it. The extensions just don't seem like a reliable fix. I really had no plans to touch power on this car. I know as soon as I get the tune I'm going to want to fix the waste gates, replace DVs and intercoolers and before I know it all the money I have for my suspension is gone. All because a little light on the dash is so irritating.

Thanks for everyone's help.

 

The extensions are a reliable and cheap fix,,,why not try that first if you dont care about more power?

 

I personally have never heard of anyone getting caught using extensions and failing due to that...

 

I guess technically he could fail a visual inspection if they saw the extenders. It is Kalifornia he's dealing with after all!!

 

Are they? I was basing it off comments in this thread like when you said "most of the time." and the Vivid guy saying "the guaranteed fix would be going with a Softronic flash." Of course the Vivid website also says the exhaust wasn't supposed to throw a CEL to begin with, so he's probably just pushing the expensive fix at this point

I guess I'll give extenders a try if the CEL pops up again. I erased the code last night and it hasn't come back on so maybe it was a fluke.

 

If they where going to check for extenders,they would first see that his exhaust is not OEM and not CARB approved....

 

Reality of it is,, I think we all can say safely that nothing is guaranteed in the High Performence world once you start modifying and each circumstance is different...lol..
Good Luck

 

Does anybody make o2 sims for the 996 turbo? I would just go for a softronics or EPL tune and be done with it but I am a power junky.

 

Price was right on the EPL tune, just called them and ordered.

 

Dumb question but are you sure you didn't install them backwards? As in you put the post cat o2 where the pre cat o2 sits?

 

yeah Im sure. The cel didnt come on immediately it came on a few hundred miles later. i cleared the code and it hasnt come back. after calling EPL I bought their tune today. the dude on the phone was so ****ing nice and gave me a great deal, i couldnt help myself. i thought the tune would cost much more. i still have plenty of money left for my suspension mods i want to do.

 

Glad you got it worked out.
Quick question didnt the light come on after you filled up with a tank of gas?

Like you said it typically will not throw a code but the free flowing cats do leave less room for error.

 

You will be glad that you did a tune, it will be like a new rocket...Plus you can not beat the tune with his price.
Enjoy..

 

Thanks for the info Steve, do you know who makes the 90 degree extenders that you mentioned?

 

Here they are right here my friend:

It's offered by a 6Speed approved vendor, so no problem sharing the information here. I stumbled upon these the other day and was intrigued, but have no experience with the parts. Best wishes, and I'm sure you could send them a few questions.
