kinetix h/f cats dyno results...not good.
dyno with kinetix cats: hp=237, tq=227, a/f=14.1 (LEAN).
dyno with stock cats on same dyno: hp=242, tq=239, a/f=13.1
What are your results with these cats? Was it just MY cats, or are others getting similar results with kinetix cats?
dyno with stock cats on same dyno: hp=242, tq=239, a/f=13.1

there are MANY variables when getting dyno numbers. Dont be discouraged, as I have seen various results with the cats, but no one has lost power.
Make sure both dyno results were SAE corrected, and similar warmups were done for both sessions.
Its very hard especially when you are talking about 3-6hp numbers to get consistency.

If none of what you have seen has lost power, then it must be that just MINE are defective.

What's up Matt! I hate to say it but I think you just got a bad set of cats. Cause as you already know I pulled 255hp/247tq with my cats (plus cai & borla). Is kinetix gonna give you your money back? Or swap out the cats for you?

I imagine it is possible that the internals of the converter have possibly collapsed.
It has never happened with our cats before, but I know it was a problem with the RT cats.
Give me an email at jamisonl@msn.com with original order info and I can have a new set sent out. I can send you a new set with a return shipping label for the old ones so you wont have any down time.

Re: 6 pulls on same sae-corrected dyno
The results seem kind of weird. I have Kinetix cats on my G, and nothing else. I definitely noticed a little more power (butt dyno), though I don't know how much leaner that I'm running.

Since your A/F is around 13.1 with the stock cats(which is quite high already), you could be losing power because the cats are making you run too lean. If you get your A/F to the low 13s with the high flows, you will probably see more power! A Low 13 A/F ratio is where our cars make the best power. So you are already at that A/F with the stock cats, and that might be why you are making more power with the stock ones!

Lets see the charts...
Also, how soon did you redyno? While I don't have any evidence to back this up, I'm pretty certain the Z likes to pull timing when theres a sudden change in A/F. Takes some miles (maybe 100?) and some on/off cycles for it to settle. I noticed this every time I made a change on either side (intake/exhaust).

Thats Unfair man. I havent heard of a V4 cracking yet.
I think how hard Kinetetix has worked with their customer service and their vigilant presence on the forum should earn thm the courtesy from EVERYONE to abstain from making rude sweeping generalizations such as this.
Does'nt seem like You Wicked.....
What ZX said makes sense. I think you should reset the ECU and try again. Running lean should not make you lose power like this. There has gotta be something wrong with the cats.
I believe Kinetix gets their cats from Carsound just like Random tech so its likely they are bad.
Can increased backpressure lead to a lean mix??

I noticed that you said you've had them for 2 months (your 2nd post). That should be enough time for the ECU to adapt.
Lower octane gas and a lot of other variables can also effect the dyno results.

Actually, a decreased backpressure usually leads to leaner A/F.

Although I can appreciate some of the opinions on his low numbers I have a hard time believing he would have had to reset his ECU after 2 months with the cats. I was at the dyno day with him and the dyno was consistant all day. With POP charger and y pipe back exhaust i put down 240HP. With a max A/f of 13.4. Something is wrong with those cats. If Brimstone who was there with us put down 255 with same cats, Borla, and Injen, and Steel Heals put down 254 with same cats also its tough for me to believe that its just his ECU that needs to be reset.

Nobody had an ECU reflash out of that eyno group?
Assuming no ECU reflash, he could have had a somewhat lower octane gas, or even something weird going on with the ECU. If the problem is the cats, that might mean that they are essentially contributing less backpressure than typical cats (meaning that they have no material inside of them!) Kind of funky.

I know the RT's flow more than the Kenetics, but tend to collapse more. Regardless, the Kin's flow more than stock, so not sure what to think here.
My guess is the leaness is causing your power loss. Contrary to popular belief, leaner does necessarily mean more power. You will hit peak mean power at about 12.7:1. Now, the F/I guys go richer to avoid detonation and higher EGT's. But you will make less HP at 14:1 vs. 13:1..no question there. I observed this same condition when I setup that group Dyno Day at Strict Dyno a couple months ago. The leaner guys were making consistently less HP than the 13:1 guys.
