Pretty sure I've still one that I bought as a spare and is surplus since I sold the car. I work at Altona North so easy to get it to you. PM me if you're interested.
I'd check with the RWC mechanic first if he'll accept complete removal of the rear muffler. I'm not 100% on the rules there but easy to make a phone call to check rather than have hassles during the re-check.
