The HG Motorsport Pre Cat Eliminator (pre-catalyst replacement pipe) can completely replace the standard component. Its precise fit and high-quality materials make it a dependable solution. Optimising the diameter, pipe routing and catalytic converter can significantly reduce the load on the turbocharger. Lower back pressure and reduced thermal load provide a noticeable increase in torque and power, together with earlier response and improved durability.
