Product Information

Full details

The Milltek GPF Back Exhaust System is designed for performance enthusiasts who want to enhance their vehicle's power delivery and acoustics without sacrificing daily drivability. By replacing the rear exhaust section from the Gasoline Particulate Filter (GPF) back with wider, high-flow pipework, it optimizes engine breathing and reduces back pressure for a noticeable performance boost. While it delivers a sportier exhaust note, users should be aware that installing aftermarket exhaust components may alter the vehicle's original manufacturer exhaust resonance profile.

FAQs

Does this system require an ECU remap?

As this is a GPF-back system, it generally does not require an ECU remap, though a remap may further optimize the engine's ability to utilize the increased airflow.

Is this system road-legal?

The Milltek system is designed to perform within standard operating parameters, but you should check your local vehicle modification regulations regarding exhaust noise levels.

Will this affect my manufacturer warranty?

Modifying the exhaust system can potentially impact certain aspects of your vehicle's manufacturer warranty. We recommend checking with your local dealer.

What is the primary material used?

Milltek uses high-quality, durable materials designed to withstand the heat and environmental stressors of performance driving.

Can I install this at home?

While the system is designed for direct fitment, access to a vehicle lift and proper exhaust tools is highly recommended for a safe and successful installation.

Troubleshooting

Exhaust rattling or vibrating against the bodywork

Adjust the positioning of the hangers and ensure all clamps are securely tightened to provide proper clearance from the underbody.

Exhaust sound is louder than expected

Check that all gaskets are properly seated and that there are no leaks at the slip-joint connections.

Setup, Compatibility & Care

This system is a direct-fit replacement for the rear section of your exhaust starting from the GPF. It is essential to ensure that your vehicle model is compatible with the `SSXFD257` part number before installation. While the system is designed for a hassle-free install, we recommend professional fitment to ensure all hangers and clamps are perfectly aligned to prevent vibration against the undercarriage. For long-term care, occasionally inspect the clamps and connection points to ensure they remain tight and free of road debris, and clean the finish with non-abrasive products to maintain the black coating.
