Hey who is running catless mids? Im about to do longtubes/heads/cam and curious who has good luck/opinions with catless mids? I currently have the idea of putting in the GESI green cats, which should hold up to 1k hp hopefully.

Thoughts?

In your other post you said you had catless mids on your old build and you thought they were terrible. Not sure why you're asking since you apparently already have an opinion. That said, I like mine. On 93, they're a bit stinky but not while running e85

I believe 1K HP will eventually burn out any set of cats.

Just make sure if you use the GESI cats, you use the Gen 2 (PN 85230). They will hold 850hp per bank. The Gen 1s could hold up to 500hp per bank but there are some who claim they've managed to burn them out. I can't verify that though.

Thank goodness!! Thats what I ordered. Man I am happy now. I can push this to 1300whp + and be safe then.

I ran stock cats on my 892whp Hellcat, which is just over 1000hp at the crank for 3 years without any issues. I have run the Gen 1 GESI cats on my ZL1 for just over a year, but it only make 700whp, or 800hp at the crank without any issues.
