Checked with the company and they said it doesn't need replacement if they are in good shape. They gave me part # 18307553601.

Finally got the downpipe installed and I have to say the turbo sound is SO much more pronounced now that you can hear it through the exhaust. Is this typical? The exhaust is now 2x louder than before but it is not overbearing especially at cruising speeds.
