Designed to Fit:

These OPF replacement link pipes from Cargraphic sit between the primary muffler and the headers to enhance flow and performance on your GT4. Available with and without high flow OPF filters.

  • Suitable for CARGRAPHIC and original exhaust components
  • 2.5 "/ 63.50mm tube diameter for the axle tubes lead into a Ø165mm housing with 2 x 2.5" / 63.50mm outlet flange diameter
  • Maximum throughput due to the increased volume and expansion space , resulting from the Ø165mm housing and correspondingly large cone connections
  • Without filter insert to reduce the exhaust gas back pressure with mixing chamber in front of a double-flow outlet flange
  • Manufactured on a CNC pipe bending machine with mandrel support (mandrel-bent), which enables exhaust pipes with a constant diameter.
  • All holders and fasteners as on the original parts
  • All CARGRAPHIC OPF models correspond 1: 1 in shape, attachment and connection to the series Otto particle filter. This elaborate construction enables the factory fastening elements, heat protection parts and sensors to be easily adopted. In addition, the cylindrical design ensures a 100% exact fit and maximum stability with the end pot holder. Maintaining this construction is essential, because without it, the enormous leverage will inevitably lead to cracks .

  • Laser cut SS304L lightweight stainless steel holder for optimal stability and durability
  • Reduced exhaust back pressure
