| mufflerI've had great luck using a secondary in-line muffler along w/ the Century muffler, as well as the stock steel can types. Performance is VG, and the sound level is practically the same as the Zim wrap-behind. This secondary muffler as I call it, is the kind used on the stingers of non-muffled tuned pipes on gas boats, and they are only ~$25.
Note: I've never tried this on the PU series Zen, only the RC230 which likes back pressure anyway. Let me know if you'd lke more info.
