Has the fuel smell disappeared for you?
In my respect with no cats it is impossible to drive with the windows down to not have your clothes smell.
After I put them on, at idle it is not noticeable but with decent or wot there is a chance I smell it. Seems like it depends on how the turbulence or wind is blowing.

for clarification, are these cats $363 for just one cat? so like $726 for a set of 2?

I read this interesting article few days ago when i was trying to find some stuff on gesi/vibrant cats. They also have a youtube channel

I just got my headers installed and can't stand the smell. I'll be buying magnaflow cats because my pocket isn't deep enough for gesi cats. I noticed some people installed the cat right before the o2 sensor, is this necessary if I have the o2 simulator from ppe installed? Or can I just install the cat after the o2 sensor without any CELs?

In my case I just did since the shop was convinced I could get away without simulators since I got these gesi. I never tried and left the simulators as is.

I'm probably going to go with GESI even though they are more expensive. From the research I've done they lose less than 1% from what they claim with their proprietary metal stainless steel honeycomb structure.
Here is the cheapest I've found it so far: https://www.amazon.com/Vibrant-Perfo...ytic+converter

Vibrant Gesi 7525 lowest $337 a piece. (x2) on Tunersports.com
I don't think I can't justify that kind of money for Gesi ones. I am sure the power difference is negligible in comparison. PPE uses Magnaflows on their Dual system with documented gains.

Sorry I'm a bit late to the thread, but I i would not even bother with Magnaflow cats. I had them om my PPE dual mode and they rattled loose fairly quickly and almost lodged in my exhaust. I then bought GESI cats and put them through some very rigorous driving with no issues at all, thankfully. My advice, pay the money for quality and peace of mind. Otherwise, you'll probably end up paying twice lol.

can anyone running either or give us any updates on any current issues with either cats i should consider...
im stuck between the Magnaflows from RR-racing or ordering the Gesi. car is only being a DD. It'll sting to spend the extra coin for the Gesi but I am looking for longevity. But if i can get the same from the Magnaflows for a third of the cost...
i read up in this thread the main thing is hard heat cycles is what kills the Magnaflows quicker and that's typically track driving, which i don't see myself doing in the near future.
