3” Next Generation Silencer System (Trumpet Tip Replacement)

For nearly three decades the most common exhaust tip in use was the aluminum trumpet style exhaust ports. Unfortunately, with the latest noise regulations now in place this poses a significant problem due to the fact that there is no way to mount or integrate a muffler/silencer to the trumpet tip. These newly designed silencer tips share the same diameter mounting flange and stud configuration as the original trumpet style tips did. They extend 6-1/2” long from the transom mounting flange to the end of the tip and offer a convenient 3” hose connection. Each set comes complete with external flappers. Sold in pairs.

4" XPM525 Performance Transom Mount 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.

Cyclone Transom Mount Series Silencer: HP-T1
4-1/2" Straight Cut with 4" Hose Connection Rated For 600 HP and above

This model Cyclone series silencers offer all of the same distinctive construction features along with the advantage of sharing the feature of the exhaust tip, by incorporating the silencer and the tip into one unit This unit is perfect for a factory looking installation The transom mount series is available in 2 specific sizes for horsepower ratings: 1) 500 plus HP and 2) 600 plus HP Both a straight and an angled slash cut version are available Sold in pairs.

The Cyclone series silencer systems have quickly become the worlds most sought after exhaust silencer systems. Through Aerospace inspired technology, the cyclone series silencers use an exclusive delta style core surrounded by a sound expansion chamber. This design have been proven to accelerate airflow through the silencers while redirecting the sound airwaves to reduce harsh exhaust noise. Adequate noise reductions of as much as 20% have been experienced without adversely affecting horsepower or torque. These silencers are constructed of nothing but the best in 316L stainless steel materials offering the very longest life span and superior corrosion resistance. Hardin Marine recognizes that there is no way that a "one size fits all" silencer could meet every boaters needs. Through extensive research and development, the Cyclone series silencers have been designed in four specific sizes, offering the perfect balance of power and noise reduction for any application.

Direct Replacement 496/496HO Silencer System (pair)

This silencer system was specifically designed and tested to comply with the J-2005 SAE testing standards that are being rigorously implemented on national waterways.  The apparent problem that the Mercury 496 & 496HO is an open exhaust configuration that does not comply with the latest noise level limits required by law.  This can now be rectified with these direct replacement silencers.  In recent testing by "Hot Boat" magazine this system dropped the noise level to a legal 85/86 decibels.  Each contains 1 pair of highly polished 316L direct replacement silencer tips plus 1 pair of external exhaust flappers.  Sold in pairs.

Full Time Tomahawk Silencer (pair)

The new Tomahawk muffler is the best on the market and it's affordable. They are available in both full time and air actuated diverting models. Now high performance engines can be run at full throttle in the closed or full time position with minimal if any back pressure. These mufflers are designed to have a minimum 150% cross sectional area. This means more airflow and more power for you to enjoy. Maybe the best feature of the air actuated system is that there are no actuating parts visible from the outside of the boat. No ugly actuators, just clean lines.
