EOS makes resonated cat-delete pipes that retain the factory heatshields, and they're cheaper than 2M. They're a forum vendor too.

Agree, they are dicks for sure. I have seen videos of people cutting stock cats open and gutting and rewelding.

Gopro max, the ghecko 3 suction mount (wouldnt recommend, I had to make a support beam and the suction cups I do NOT trust, I have had issues already without actually drag racing yet.) I am still figuring out a reliable setup.

Still not certified due to grade but they def added some 60-130 power. Best I could muster before was 7.6. (It was colder in this pass than the others)

Crazy there’s a decent price jump for all the aftermarket sport cats from Stingrays to Z06s, when they most likely just bolted up their already produced Stingray sportcats, it’s not like there’s some crazy R&D
costs associated.

Well that confirms it. A few months ago I was 99% sure just based on doing the same cat job on both my stingrays and now the Z. That paired with the fact they use the same gaskets lol

wow, interesting. No wonder they pick up power without them or with high flow. Good find!

Ordered the EOS high-flows. Great deal for 360 delivered.

They have o2 spacers welded on, but you may need additional o2 spacers if a CEL pops. I'd recommend Big Daddies Garage angled spacers for quality that fits correctly and won't rust.

I'd also suggest a brand new set of 4 OEM gaskets to prevent having to go back in there again.

Looking to get these as well for up upcoming Z. They don't seem very helpful according to their website, are there any known fitment issues?

I have fabspeeds on my stingray, went in smooth

No fitment issues and no CEL. Get new OEM gaskets though cause the 2M supplied ones are trash. Also use Ultra Copper on O2 sensor threads. Leaks, even the smallest, will be a CEL. I used titanium heat wrap on mine as well. No issues at all

Helpful info. With the part numbers matching up can anyone confirm pipes from a stingray fitting a z06? I can take measurements of my oem stingray cats if it helps
