This ER Spec Magnaflow catalytic converter was created for the Nissan 240sx 89-98. It’s a high flow, 3 Inch catalytic converter with a honeycomb design that operates significantly better than any stock catalytic converter. This part bolts to any 3" SR downpipe or aftermarket header and to any Cat-Back exhaust system.
Environmentally conscious state regulations generally require some sort of catalytic converter, as these crucial parts reduce the amount of harmful chemicals that your car releases into the environment. However, the problem with a stock catalytic converter is that usually it restricts your exhaust flow, which results in lower horsepower and torque. A stock converter can also be easily clogged and needs to be frequently replaced.
