Hi...this is a OBX exaust manifold header,that fits sohc Saturns from 93 to 99.It has 4 longer,and wider stainless steel pipes,and a wider then original flex pipe that goes in the cat.converter.The stock exhaust manifold was to heavy, and it wasn't built to let the exaust move fast enough,that creates a back pressure in the system that reduces torque and horsepower.
Hi Whitey...i will call Auto Zone to see if they still sell "universal"o2 sensors.The reason i upgraded,is to get better torque.This engine has around 85 horse power,and is great on gas.This is for city driving only,so my goal is to improve the 0 to 50 time,and leave the fuel system,all original.
