By reducing exhaust resistance, the J's Racing Stainless Steel Downpipe improves power & torque in all rev ranges. It is made of SUS 304 stainless for rust resistance and excellent durability. It is equipped with a base for O2 sensor to maintain the stock check engine function. This is the newest version from J's Racing, which features an additional A/F sensor fitting hole (total of two sensor holes). This provides convenience and takes care of the sensor location difference between AP1 and AP2. The hole is easily capped with a bolt included in the set if it is unneeded. Furthermore, the stock heat shield for the stock catalytic converter can be installed to protect the product.
