Product Information

Full details

The Milltek GPF Back Exhaust System (SSXFD260) is designed for performance enthusiasts seeking to optimize their vehicle's engine efficiency and auditory profile without sacrificing daily drivability. This system replaces the factory exhaust components from the Gasoline Particulate Filter (GPF) rearward, utilizing high-flow pipework to reduce back pressure and unlock increased power, though owners should note that this modification primarily targets sound and flow improvements rather than extreme track-only power gains.

FAQs

Does this system require an ECU tune?

As a GPF-back exhaust, the system does not typically require an ECU remap to function correctly, though a tune may help you extract the full potential of the increased flow.

Is the SSXFD260 road legal?

Since the system retains the factory GPF, it is designed to comply with standard vehicle emissions regulations in most jurisdictions.

Will this cause a check engine light?

No. Because this is a GPF-back system, it does not alter the sensors responsible for monitoring emissions, so it should not trigger a check engine light.

Can I install this at home?

While it is a direct-fit product, professional installation is recommended due to the need for vehicle access and correct alignment of the piping.

What material is the exhaust made of?

Milltek systems are constructed from high-quality, corrosion-resistant stainless steel designed to withstand harsh road conditions.

Troubleshooting

Exhaust is vibrating or hitting the chassis

Adjust the alignment at the clamp connections and check that all rubber hangers are seated correctly.

Exhaust tips are uneven or misaligned

Loosen the rear section clamps, reposition the tips to your preference, and retighten while holding the pipe in the desired orientation.

Mild smell of exhaust or smoke immediately after install

This is often residue from the manufacturing process burning off the pipe surface; it should dissipate after the first 30-50 miles of driving.

Pros and Cons

Pros

  • Improved engine throttle response due to reduced back pressure
  • Sporty, signature Milltek exhaust note without intrusive cabin drone
  • High-quality construction and durability standards
  • Engineered for direct-fit, simplifying the installation process

Cons

  • Does not replace the GPF, which limits the total possible sound increase
  • Performance gains are noticeable but may be modest compared to full turbo-back systems
  • Requires professional tools and lift access for optimal installation

Setup, Compatibility & Care

Installation of the SSXFD260 is designed as a direct replacement for the original equipment manufacturer (OEM) system. Because it is a GPF-back system, it complies with regulations regarding the Gasoline Particulate Filter, meaning it retains the factory emissions setup while upgrading the downstream pipework.

Installation Tips:

  1. Ensure the vehicle is properly supported on a lift or heavy-duty jack stands.
  2. Use new exhaust gaskets and hardware when mating the Milltek sections to the existing GPF exit.
  3. Align the exhaust tips carefully before tightening the clamps to ensure they are centered in the bumper cutouts.

Care Instructions:

  • Periodically inspect the exhaust hangers to ensure they have not stretched or perished.
  • Clean the exhaust tips regularly with a stainless steel polish to prevent carbon buildup and surface staining.
