Corsa C8 CATS Feedback

Does anyone have Corsa Cats on their C8?
Any issues to report? Check engine lights? Stink? Fit?
Just wanted to get some feedback from owners on how they like them.

They are a really good choice and use GESi G-Sport GEN2 S-Wound 400-cell cores, which are basically the North American latest & greatest. They flow like a 300-cell but are emissions legal in 49 states. I just got mine back from the ceramic coater, but based on the technology they should provide for the least amount of smell from any aftermarket high-flow cats. No CEL per Corsa and a perfect 2.75" inlet to match stock, AFE, & other aftermarket headers. All flanges utilize OEM gaskets; 1 is included and you can reuse the other 3 or do like I did and order the remaining 3 for a complete install with all new gaskets (cost me about $24 total).

Thanks for the reply. If you could chime in how satisfied you are after driving with them for a while I would appreciate it.

Certainly will! I have a thread in Tech/Performance as well.

Had mine installed for about 4k miles now and no check engine lights. Corsa still lists them as 300 cell on their website but doesn't really matter I guess, the price point is good compared to the competition.
As for the daily life, a lot more visible condensation during cold start on a humid day, I have these paired with the borla s-type so might not be the same with stock exhaust. If I am being extremely picky there is a very minor exhaust smell on a chilly day that goes away within the minute. Overall a happy customer and I like being able to use oem gaskets. The provided hardware was also nice.
Car sounds great, just the volume I was looking for and puts a smile on my face every time I drive it.

edit: EPA compliant is a nice touch and makes it a good pair with ARH headers if you care about that stuff.

The 400-cell is superior vs. the 300-cell in every way; newer/better technology and 49-state emissions legal for 2017+ vehicles (the GEN1 300-cell cores are for 2016 and older). As you said, these do pair nicely with the ARH headers and also the AFE headers since both are the only two CARB-approved headers for the C8. It is nice having an aftermarket exhaust system that is perfectly legal here in TX and will never give me an issue during annual state inspection.
