Mine is back at the shop - Powerneedy Catted DP - Keep getting P0420 permanent and pending P0141. Powerneedy said for the P0420 it could be a flaw in the fitting during manufacturing. They sent me pics of what to look for - I am hoping thats not the issue because I dont want to have to mail it...
Its the tune. No amount of coating or anything else will stop the CEL except coding it out (Which is basically like erasing the CEL every time it goes on) or running the stock tune. Once the tune pushes the engine harder you will almost always throw a CEL with a high flow CAT.
Update on mine - I was able to get some driving in this weekend and here was what I found:
My Setup - Titan Protune Piggyback, Ingen Intake, Powerneedy Catted DP
On Tune 1 - Stock - I get no CEL or pending CEL.
(Tune 2 for the Titan is for Valet and I dont use)
On Tune 3 - Stage 1 Tune - I...
I have the powerneedy Catted DP. Also got a cel sheet about 40-50 miles or so.
I think essentially there is no way around it.... I'm using a piggyback tune from Titan. I think even a full tune they just hide the cel but technically it's still there
Technically I have not had the CEL light come on yet - Just reading the codes I can see a pending which seems to go away before becoming a permanent CEL. I have not pushed it super hard for a long period yet.

How many miles have you put on it?
Thanks GCole - Do you actually get the code or just the predicted code? I have not seen the CEL light YET - but have seen the predicted P0420 and then it goes away. I only have about 60 miles now with the new Powerneedy Catted DP - You have the same one?
If you do get the code - do you just...
Hi Titan..... I have emailed more than once and didn't get a reply. Hoping you will reply here.

Also have the powerneedy Catted downpipe and ingen intake.
Running map4 and seeing a pending p0420 cat efficiency code. Has not kicked on engine light yet...

I'm chasing my tail?
I guess I will try myself - I have watch the vids and it seems straight forward. (Notice I didnt say easy - Cause it wont be for me!!!) But I think I can get it done. First I will warm up the car so the exhaust is nice and HOTTT
Now that my check engine is all cleared up for the evap canister -
I ordered a few items for performance and aesthetics. I may attempt the DP myself - But if not - Anyone have a recommendation for a shop in South Jersey that would do it???
I do not want just a muffler shop or similar - In the...
