Got FI non-res test pipes installed, rattle is gone. Car sounds 10x better.
But, issue is I kept getting a CEL on the res HFC's. Too lean Post-cat issue. JTran re-tuned and added more fuel throughout the map. My CEL light is still on after the test pipes. JTran told me it's probably running too rich. Going to it retuned next week. If the CEL goes off and doesn't come back, I'll know it was the cat. If it comes on again, I'll have to figure out what the issue is.
I'll update after I get it re-tuned.

Wynton,
I hope all is well and I'm glad to hear that you've got your test pipes installed.
This is the first time seeing these pictures. I'd like to point out that this is not a common occurrence with our resonated high flow cats or resonated test pipes. We've sold hundreds, if not thousands of units over the years, and I've maybe seen this happen on 1 or 2 occasions.
We stand behind our exhaust products with a 3-year warranty on all welds and craftsmanship. We also offer a 3-year warranty on the internal packing material of our mufflers / tips / resonators. Our warranty holds true given that the parts have never been "bottomed out" on the ground or damaged due to negligence. The parts also need to have been bolted directly to our exhaust products or the OEM exhaust products.

As for your CEL, in 2013 and above 370Z, Nissan made some changes to the O2 sensors and they are a little more sensitive than the older model Z. We incorporate j-bend style O2 anti-foulers in our test pipes and high flow cats. This method has worked great in the past at keeping that pesky CEL off. In the rare occasion that the CEL turns on, it can be corrected with a tune.
If you have any questions, please don't hesitate to send me an email.
GOOD LUCK WITH SALE!
