Can anyone recommend a site to buy a cat converter?
I was wondering if any of you could help me find a website to buy them? The shop said I needed both sides. It's a 2012 g37xs sedan.
I don't need fancy ones, I'm not an enthusiast, there's 92k miles on the car, the cheaper the better.
Some local shops wants to charge me around 2 grand for the pair and install, which I cannot afford.
I appreciate it guys.
edit: https://www.ebay.com/itm/263803447023 $260 for a new pair on ebay? Will that work?

You'll want to look for HIGH-Flow cats. They can be had anywhere from $300-$600 depending on brand. I have Fast-Intentions. Good quality brand. They are on the higher end of the price range. They are built to order meaning you may have to wait 8-12 weeks after placing a order before they get delivered to you. If you do not want to wait that long than there are multiple of other brands.
I have been running Fast-Intentions high-flow cats for 3 years now and the only time I had a check engine light was due to a exhaust leak. I bought my FI High-Flow cats used from another member and they were developing a hairline crack over time. I got it removed and sealed the crack by paying a shop to weld over it and everything is good.
My car is a 2011 G37S RWD with 90k miles. I've had the FI HFC installed since ~35k miles.

Dealer said just my left cat was bad.
I did some research on the z1's pair vs. the kinetix, and I ordered the kinetix's one's. Thanks for all of your help replies qmantran.

I believe he's saying the kinetix one are more prone to throwing a light for those cats.
They don't appear to have the defoulers built in like the FI High flow cats or Z1 cats that I mentioned.
however the description for the kinetix states they don't trigger a check engine light due to retaining the factory o2 sensor location.
let us know how they work out for you.
I would have went with Z1 if I was on a budget. They come with Z1 steel gaskets (reusable) and defoulers (100% no engine light)

Got a deal, was only charged $160 for the install. The CEL was not thrown.
regarding the new kinetix cats.
-can feel vibration in my seat and door while at idle now. It's not annoying, but it wasn't there w oem's.
-while hard accelerating it sounds like a go kart or bug on a summer night. The orginal oem cats had a deeper mean sound to them
-no noticeable power gain
-cruising speed no noise or "drone" in the car, sounds normal
-my original acceleration issues appear to be fixed.
So overall not really a fan of the acceleration sound, but these were only $400 compared to oem's so, I'm fine with it.
Thanks everyone for all the input.

Glad you found a reasonable shop for the install and it worked out to your satisfaction. Should notice some gain, but going in you weren't really wanting them so that may play a part. If you were really wanting them you'd find some gain there, lol. As far as the seat vibration, I have that w/ my resonated test pipes but only really noticeable at cold start ups, once it's warmed up not much difference, is that the case w/ you Mr Jones?

I don't see any support brackets on the Kinetix cats. The OEM cats are connected to one another, and the underside of the transmission, with a single C-shaped support bar and thick bushings. If this install did away with that support bar, that's probably where you're getting the vibration.

Look what just popped up in the classifieds. If the vibration and noise really bother you, you can just buy these and sell the kinetix.
