Installation Notes

Because this is a universal muffler, installation may require exhaust fabrication, alignment, or additional parts to match the vehicle’s existing routing. Verify inlet and outlet diameters, offset configuration, and available space before installation. For best results, confirm the exhaust path on the specific GMC or Chevrolet application before welding or clamping the muffler into place.
