2ZZ-GE HJS 200cell Catalyser
Take a look. No other manufacturer comes close to the quality and design of the 2bular catalysers.
I use a 130mm diameter HJS Directional 200cell catalyser. It has the legendary build-quality from the German manufacturer and with 5 times the weight in coatings of the rare metals required for the catalysing process compared to the cheaper aftermarket offerings, will easily meet any emissions tests, yet still improve gas-flow and performance.
It uses a TIG-welded gasket cup for strength and integrity, with a stainless reducer to guide the gas down the correct bore downpipe - 63.5mm diameter.
Other designs I see use a 70mm pipe because you can form the gasket cup from that size without having to weld the flange in place. Lazy, lazy cheap people. I use 70mm diameter on the 350bhp supercharged V6 - NOT on a 170bhp N/A motor!
