Does installation require cutting or welding?
Requirements depend on the exact system and vehicle. Review aFe's current instructions before disassembly; some configurations are bolt-on while others require trimming or professional fabrication.

Will this exhaust change sound level?
Sound depends on system type, pipe diameter, resonators, mufflers, engine, and other modifications. Confirm the exact configuration and local sound requirements.

Does this exhaust retain required emissions equipment?
Only when the exact product is designed around the original catalysts, DPF, or other equipment. Confirm current emissions classification before installation.

Installation Instructions

  1. Confirm aFe part number 49-42079, the complete vehicle or specification-based application, and all required supporting components.
  2. Allow the exhaust to cool, support the vehicle safely, and compare every pipe, hanger, flange, sensor, and included clamp before removing factory parts.
  3. Assemble the system loosely from the fixed connection points, align tips and clearances, then tighten hardware in the manufacturer's sequence.
  4. Check for leaks, contact, sensor faults, and loose hardware after the first complete heat cycle.
