Q. What is Selective Catalytic Reduction (SCR)? A. SCR is a technology that uses a urea based diesel exhaust fluid (DEF) and a catalytic converter to significantly reduce oxides of nitrogen (NOx) emissions. SCR is the leading technology being used to meet 2010 emission regulations. Q. How does an SCR system work? A. <IPv6Freely> meh emissions laws are no big deal. its not like theyre strict <IPv6Freely> i mean if you cant pass CA emissions, you really shouldnt be on the road anyway :P <Nieros> Well, as a gear-head I have a slight aversion to things like catalytic converters
The factory catalytic converters are well known as the biggest "choke point" in the factory exhaust system. These high flow CARSOUND/MAGNAFLOW catalytic converters blow away the stock converter flow rates while still maintaining legal emissions levels. Constructed with stainless tubing and 3/8" stainless flanges (converters are aluminized steel).
