So, anyone with catless setups have any luck with emissions with this product?

This is what I used on my Whipple F150 when I removed the cats.
I used two kinds and double stacked them; Medium length stacked on a short one. Worked great. No lights.

Yes, but get the ones with the inserts in them. Use the medium insert and good to go.
