4" XPM525 Performance Clamp-on Mufflers

Hardin Marine has just introduced their latest performance mufflers, the XPM525. These new silencers address the J-2005 SAE test that is now the standard in many states including California. In a recent independent test, these silencers showed a 12.2-decibel noise reduction at idle speed when mounted on the Mercury 525 engine package. This brought the test boat down to 88db passing the stringent California noise ordinance enacted this year. When installed on a test boat equipped with the 496 engine package, the mufflers brought it down to 88db.

The XPM525’s are constructed entirely from 316L stainless steel in order to provide the maximum corrosion resistance available in saltwater applications. These mufflers do not have any moving parts or packing to wear out. The significant sound reduction is accomplished with a 5-inch 2-phase expansion chamber in conjunction with a center sound wave baffle. The unique down-turned design helps to keep spray and carbon residue from accumulating on the boats transom. Heavy-duty external exhaust flappers are included to prevent any chance of water ingestion through the exhaust system.

Installation is simple. The XPM525 muffler system is designed to clamp onto any 4” O.D. tailpipe or exhaust tip using an integral stainless band clamp and a 1/8” set screw for added security. The mufflers are 12-1/2” in overall length.

The meticulous hand polished finish bring these mufflers to a show quality shine making them a beautiful addition to any boat while maintaining their necessary functionality. Sold in pairs.
