Gasket & Hardware Kits - We have pieced together all of the necessary parts to make swapping out your factory catalytic converter a breeze. This kit includes turbo outlet and cat-to-mid pipe gaskets, as well as all necessary nuts and bolts for a complete install.
Oxygen Sensor Spacer - This spaces out the secondary (rear) O2 sensor to remove MIL or CEL issues caused by removing the factory catalytic converter. Professionally manufactured from stainless steel, not cobbled together by hand like some other products on the market. Spacer will add approximately 1.7" to the height of the sensor. 034Motorsport oxygen sensor spacers feature a flare seal seat, so no sealing washer or gasket is required.
