Curious to see if anyone here has plunked down the cash and uses these catalysts? They look top quality, and from the all metal construction probably hold up great in the long run. Running these with a nismo exhaust would be a awesome combo, for both power and sound.

The NISMO HF cats are sweet...! Beautiful construction and they seem to be top notch as far as internals. HP/TQ to $$$ ratio, I honestly don't know. If I was loaded, I would probably buy them But I'm not, so the closest HF cats I could find were the HELIX DNA series with 200 cel metal substrates. I have a thread somewhere around here with all the info if your intersted. Less than half the price...

Good luck, either way you come out a winner!
