Ok I have read many posts that talk about an ORP. I still have yet to grasp WTF it is. I know it has something to with exhaust and it makes it loud. What does it stand for and where can I obtain this ORP?
Daeron said:An ORP replaces the stock cat...it is louder and you gain HP, but you lose back pressure and thus lose some torque, but not too much.
