The cats are specially manufactured for TORQEN. The interior substrate is made from an ultra-thin metal foil. The foil itself is a made up of a combination of iron, chromium and aluminium. The substrate is more resilient than ceramic core substrates and so is ideal for high performance use. 200 cell cats cater for the latest version of OBD2 Standard, so in theory these should pass MOT providing they've been properly heated before the test.


The catalyst is comprised of corrugated stainless steel foil, interlaid with stainless foil sheets to prevent nesting. As the ceramic, the coating process if very strictly controlled to ensure that the precious metals within the wash coat are evenly distributed throughout the catalyst. This is to accomplish two very important objectives: provide maximum emission reduction and prevent any excess wash coat build-up that might clog the cells and reduce flow performance.


The metallic catalyst does not require a mat to cushion it within the stainless steel shell, as it is not brittle like ceramic. The outer layer of the metallic catalyst is actually slightly crushed when the catalytic converter is assembled, locking the metallic catalyst securely within the catalytic converter housing.


These will come with bolts, nuts and gaskets, ready to fit.

Automatic Vehicles: Please be aware, you may need 90 degree O2 spacers as the extended bung touches the gearbox

Text: Fantastic HFCs. They have passed 3 UK MOTs so far. Very happy!

Bought these for an automatic 370z years ago (and maybe responsible for the automatic disclaimer haha) alongside an Invidia Gemini system. Fitment has been fantastic. Torqen support were also great when I ran into the automatic gearbox fitment issue too. The lambda extension brackets were a requirement to prevent the CEL light coming on.

Would highly recommend.

Text: Really great HFC's - the Z sounds even better now. The noise is not raspy and the smell ofc is not so bad. They do not smell like stock cats, its barely noticeable. I had some problems with customs (UK to EU shipping).

They are worth and I hope they will do they work great :) No CEL for now but we will see in some time. (on the car for a week now.)

Highly recommend compare to the pricing of competitors.

NO CEL thrown when installed, the build quality & speed of delivery of the product superb.

Compared to the pricing of competitors for HFC’s cannot go wrong with this product would highly recommend.
