This decat mid pipe allows you to eliminate the stock catalyzer from your exhaust system, allowing for a more free flowing and unrestricted exhaust flow. Arrow has designed this link pipe to fit your stock headers. These are often combined with an Arrow Slip-On exhaust to create a "half system".
Note: This link pipe is designed to fit the stock exhaust and headers. This allows this decat link pipe to fit any aftermarket exhaust that fits in the same manner as the stock exhaust.
