Super 40 Series Muffler

The Super 40 Series Muffler is a universal exhaust silencer engineered for mechanics and enthusiasts seeking reliable, cost-effective noise reduction across a wide range of vehicle platforms. This steel-constructed muffler fits applications requiring a 3-inch offset inlet and 3-inch center outlet configuration, making it a practical upgrade for custom exhaust builds, restoration projects, and performance tuning where OEM mufflers fall short. Whether you're fabricating a cat-back system or replacing aged factory equipment, the Super 40 delivers consistent sound attenuation without requiring platform-specific mounting brackets.

Built with a 13.5 x 10 x 5-inch oval chamber body, the Super 40 Series uses internal baffle tuning to absorb and disperse exhaust gases efficiently while maintaining acceptable backpressure for naturally aspirated engines. The black powder-coat finish protects against corrosion and road salt, extending service life in harsh conditions common to daily drivers and work vehicles. At 19.5 inches in length and 13.3 pounds, this muffler strikes a balance between acoustic performance and compact packaging—critical when working within tight underbody constraints or modifying vehicles with limited clearance. The welded steel construction ensures durability through thermal cycling and vibration exposure inherent to long-term street use.

This muffler benefits fabricators, transmission swaps, and enthusiasts who need a universal solution free from OEM packaging restrictions. It integrates seamlessly into custom exhaust systems for trucks, muscle cars, hot rods, and import platforms—anywhere a 3-inch dual-outlet configuration makes sense. Installation requires basic welding or clamp-band assembly depending on your existing piping; confirm inlet/outlet alignment and ground clearance before committing to fitment. Stock this part for quick turn-around on exhaust work or keep one on hand for next-generation build projects.
