This combination of stepped, equal-length 4-2-1 manifold and 200cell HJS catalyser gives you the biggest power and torque gains whilst still being able to pass any emissions tests. The stepped design maintains a high gas-speed at the cylinder head and the hand-formed/TIG-welded 2-1 collectors reduce turbulence at these critical junctions. THERE ARE NO LEAKY SLIP-JOINTS OR SPRINGS TO WORRY ABOUT - THE T4 ECU DOES NOT TAKE KINDLY TO AIR-LEAKS IN THE MANIFOLD!
I USE A 121mm DIAMETER EURO 6 SPEC DIRECTIONAL HJS HD (HIGH DURABILITY) 200CELL CATALYSER FOR THIS INSTALL. WITH 5 TIMES THE WEIGHT IN COATINGS OF THE RARE METALS REQUIRED (PALLADIUM. PLATINUM, RHODIUM ETC) FOR THE CATALYSING PROCESS COMPARED TO THE CHEAPER AFTERMARKET OFFERINGS, YOU WILL PASS ANY EMISSIONS TEST AND NO CEL (Check Engine Light).
Only 2bular offer this layout for the normally-aspirated (N/A) 2ZZ-GE motor. I use different diameters of catalysers to suit the various power outputs of the Toyota motors used by Lotus. The 2ZZ-GE N/A HJS HD directional catalyser is the highest spec Euro 6. With a 121mm diameter, it's larger than the 1ZR/1ZZ designs but smaller than the 130mm diameter of the V6 supercharged installs - but it's still a BIG catalyser. ONLY 2BULAR DO THIS. Catalysers are not beneficial to power or torque and you need to pay attention to the effect on gas-flow and speed by these products.
If you have to have a catalyser fitted, the HJS factory supplies the highest quality product to all the World's supercar manufacturers. The factory ECU works very well with it and there are no CEL's.
PLEASE NOTE - I DO NOT SUPPLY THE LAMBDA SENSOR - TOO MANY BOSCH FAILURES.
