4-1/4" HCX Competition Series Offshore Mufflers

HCX Competition Series Offshore Mufflers
4-1/4" O.D. x 8"Long  (Pair)

HCX Offshore Competition Race Mufflers Design and Function Faster & Quieter

With decades devoted to marine exhaust technology Hardin Marine knows a HIGH horsepower muffler does not work by restricting flow. There is a balance between noise reduction and horse power retention. The HCX series mufflers tuned free-flow unrestricted design along their with strategically placed louvers reamlines your boats exhaust flow reducing back pressure while also adding a level of sound deadening and providing up to 8 decibels (8" version) of noise reduction and an incomparable deep, rich sound.

In order to offer maximum exhaust flow in its most basic sense and for the muffler to reduce noise, it must separate that noise (sound waves), by separating the peaks and valleys produced by the exhaust note. These sound waves are then absorbed throughout the length of the muffler, the harsh (Loud) noise notes can be some what neutralized through this technology this is exactly how the HCX series muffler achieves this.

These mufflers provide the long awaited option to the numerous 750+ horse powered boats that longed for a muffler option that wouldn’t rob them of their available horse power and that could also be easily installed and removed for various boating environments. The lightweight design is perfect for dry tailpipe applications but they can also be used in wet pipe applications. Common applications are high horsepower, supercharged or normally aspirated engines. Each muffler is precision TIG welded utilizing all stainless steel construction. The mufflers are a standard 8" length with a 4-1/4" O.D. They are easily removable with just 1 hex screw (no special tool needed, just a standard size allen wrench)

  • All Stainless Steel Construction
  • Strategic louvered design provides noise reduction

460 Ford Cast Aluminum Performance Exhaust System - Manifolds Only, (Includes Bolts & Gaskets)

The long awaited and much anticipated new Performance Ford center rise exhaust systems are now available from Hardin Marine. Hardin adapted the same technology used to develop the powerful manifold systems found on Mercury Racing’s HP500 and 540 Bulldog engine packages and integrated that individual separated runner design into this new Big Block Ford exhaust system. Hardin knew while perfect for direct replacement these also compliment today’s larger custom Ford 500 CID plus engines. These engines require an exhaust system that not only scavenges, but can also expel the massive amounts of exhaust created by these larger engines while reducing exhaust back pressure to near non-existent levels. These manifolds are cast from pure T356 aluminum and then heat treated to a T6 condition. The final steps include hard anodizing for corrosion resistance and a gloss powder coated for a stunning appearance. Individual exhaust ports are cooled by a balanced and even water flow thru the manifold. Exhaust tailpipes are available in a standard exit or custom applications and are constructed from quality 316L stainless steel.

  • 35" Overall Width on stock heads.
  • 29-1/2" Exhaust Center to Center on stock heads.
  • 8" Tall from Exhaust center-line to top of manifold on stock heads.
