By reducing the exhaust resistance, the SUS Circuit Converter improves the 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 engine check light function.

The product has been redesigned for 2012.  The new one has an additional A/F sensor fitting hole (total two sensor holes).  That should be very convenient and nicely takes care of the sensor location difference between AP1 and AP2.   The hole is easily capped with the bolt included in the set.

Furthermore,  the stock heat shield for the stock CAT can be installed to protect the product.    It enhances your driving pleasure at the track and race events.
