Exige S 2ZZ-GE Catalyser to OEM manifold
I've dropped the 100cell catalysers as they're too noisy for UK tracks and they sometimes had a problem passing emissions tests!
Here is the new 200cell HJS HD catalyser for all the 2bular supercharged exhausts. Big enough to handle the power and with the famous HJS quality good enough to pass emissions tests easily, year after year. Quieter than the 100cell designs too - something that's becoming even more important these days.
The gasket cup is TIG-welded to the flange. This allows the springs the same working length as standard and ensures a strong, gas-tight connection.
The conical reducer brings the pipe diameter to the correct 63.5mm diameter - any larger and you're losing gas-speed/performance. I've seen a 70mm diameter pipe used because it's easier to form the gasket cup on the end of that size and heh - just leave the flange loose(!) - lazy - and on the SC'd cars, you're losing boost/power.
This catalsyer bolts to the factory manifold and finishes at the same position as the factory cat pipe, so will fit to any after-market exhaust.
The revised pipework takes it well clear of the clam.
