You're welcome! I would agree, similar results from a friendlier/simpler package. Perfect example of KISS in action.

How long did the install take you?
On jack stands or lift?

I paid a shop to do it on their lift rather than attempting with jackstands in my garage. I didn't feel like burning up a Saturday laying on concrete. It was only a few hours worth of labor.

Popped a CEL tonight. It can either be tuned out or eliminated by installing non-foulers. I'll have my tuner disable the code.

AFE said it was a 50/50 chance. Non-foulers will be the ticket for guys wanting to stay on the stock tune.

I have a set of Hooker shorty's that have never been installed. I think the combo of those and these cat pipes will work great.

AGREED! I'd highly suggest getting both ceramic coated before install. Part of me wishes those had been out when I did my ported/coated factory exhaust manifolds.

I still haven't coated the Hookers so I'd probably get both done at the same time. What temp coating did you use? Local guys recommended cerakote, Jet hot wanted to do just the outside with their highest temp coating.

My exhaust manifolds are done in black 2000F and the AFE pipes in silver 1600F. That black is over 4 years old and holding up very well.

Thanks. I should be fine with that too then. Do you think 1600 will stay on the cats on track?

It should, yes. If he has 2000F you can just do that on both though. Never hurts to have a little extra headroom. With that said, the 1600F has proven to be very durable even on turbochargers in my experience.

I was hoping this would not cause codes with the cats. At this point probably better to go with Norcal catless which are cheaper and running stock X for a little sound and smell control.

Although I don't necessarily agree with you, that is one option. The secondary cats and primary cats serve different purposes though which I why I chose to delete the secondary but retain the primaries.

I've been thinking the same, but have yet to see someone do it

Disabling the CEL within the tune apparently also kills AFM mode so I went ahead and ordered a set of Big Daddy angled o2 sims so we can reenable AFM in my tune. In hindsight, I should have just ordered a set in the first place but live & learn.

On to more exciting things...the car feels amazing with the tune all touched up! My new 91-octane tune feels just as good, if not better, than my 93-octane tune did on the factory primary cats. I had just enough 93 left in my tank to get the 93 tune finished but had to immediately fill-up with 91 so i haven't gotten a chance to really experience the car on 93 now.

Kracka,

Forgive me if it was mentioned already and I missed it, are you running catless down pipes, catless x-pipe and stock NPP mufflers?

Keep us posted. Very interested in whether or not the Big Daddy sims work.

NorcalSS seems to have good things to say about them on his cat-delete pipes so we'll see!
