Maybe you want to read it again, it is a metal substate cat.

Btw, I have had a helix DP with a custom metal substrate cat fabricated in by MPJ on my car for the last 7 months. I love it. It almost feels like I have no cat at all.

To clarify, the Helix Cat is a METAL SUBSTRATE (yes all those nice rare-earth elements!!)

200 cell cat.

BTW, we're currently sold out on the catted downpipes. Next shipment is 2-3 weeks (good idea to reserve yours today!)

Ohhh pardon me... I totally read that wrong. Nice, this may be a good option then.
