Additional Description

N/A Stand-alone catalytic housings are a great bolt on solution to add to an existing silencer system.
  • Housings feature heavy duty, all welded construction throughout to optimize the performance of the catalytic converter while protecting it from the harsh environment.
  • An easy access hatch type design is incorporated to retain and protect up to two catalyst elements.
  • Continuously welded containment rings and a full perimeter gasket around the catalyst create a "zero leakage" seal around the catalyst to prevent exhaust blow-by.
  • A perforated diffuser plate and transition cones enhance even exhaust flow distribution across the catalyst for maximum efficiency and conversion of exhaust gases.
  • An internal support structure further enhances strength and robustness of the design and helps to prevent damage to the catalyst from engine back-fires.
  • Housings are available in standard sizes from 2" inlet up to 24" inlet.
  • Special order & custom designs can be offered to meet your specific requirements.
Final dimensions will vary upon emission requirements. Following are the standard size ranges:
  • Overall length (OAL): 26" to 52"
  • Inlet/Outlet diameter: 2" to 24"
  • Housing diameter: 6" to 48"
