Ok internet let’s find out what cat it is
200cell full metallic substrate with 4.5 diameter What we are allowed to say is that the catalyst core is manufactured in Illinois by a one of the largest aftermarket companies with annual sales of between 10 and 20 billion dollars.
Will there be any restrictions with going to a small cat? 4.5 inch compared to the fabspeed 6 inch?
I am also curious about the collector size seems to be smaller also..
who is going to order a set up and dyno test it?

The Fabspeed 6 inch is rated for 1200 hp or 1250 hp from youtube video they have. So you would have 2400hp of flow. So in comparison even if the 4.5 flowed half you would still have 1200hp of flow.
The header collecter are 2-7/8 inch...larger than kooks headers people have no problem buying for their C8. Lastly $2800 or $550...its worth it just for louder exhaust if that is what you are looking for. I woudn't expect any cat to produce the 17hp they advertise

Did anyone get any of these Headers or sport Cats yet?
There's a few guys in some various C8 facebook groups that took delivery and they say quality is excellent. I ordered the headers and sport cats. They were shipped out today so hopefully they arrive soon. I've got my vert all torn apart. And it's a lot tighter on a convertible. You can't have the trunk and tonneau cover at the same time.

I pulled the trigger today and ordered the headers and sport Cats tonight.. keep us updated on the progress..!
My set of 2M Headers and sport cats came in today. I plan on getting the car to the dyno for a before and after results. Overall build quality looks good, they do put a silver coating on them that I am not to sure about yet
Surprisingly it took less than a week to arrive , I am still waiting on many other parts for the car!

Are you going to Dyno it piece by piece or whole set up before and after? Also if you dont mind do a audio DB test before and after.... Decible X is a good app to use.

Those look good. Can't wait for mine to arrive. The silver coating is supposed to be a ceramic heat coating. Same as to what LTH does also. Mine will now be delivered on Wednesday. Let us know what your dyno numbers come in at.

I will install them all together along with an attack blue air filter. I will get a decibel reading for you also 👍🏼
Is this easy to do? I’d rather do this than ordering some aftermarket parts and I’m just trying to make the car exhaust louder
Easy Mod, but beware the smell can be a bit annoying especially with the top off. The high flow cats seem to be coming down in pricing with Stainless Works now offering a set with a rack price of $900.

I did a cat delete. I used the fab speed simulators. To keep the cell light out.
No good light still came on. Then GM is sending me emails about the cat code. Then the worst is the smell. It will choke you. I put on a set of high flow converters. Now, No smell, no light.
