Product Information

Full details

The Scorpion Predator GPF Back Exhaust System is designed for performance-minded automotive enthusiasts looking to enhance their vehicle's engine note and throttle response. This system provides a more aggressive, sportier exhaust tone while improving flow through larger-diameter pipework, though it is important to note that the non-resonated design may introduce more cabin drone at highway speeds compared to factory systems.

Extended Product Information

FAQs

Will this system affect my emissions testing?

No, this is a GPF-back system, meaning it retains the original Gasoline Particulate Filter and emissions control hardware.

Is this system valved?

No, this specific model (SFDS104) is non-valved, providing a consistent exhaust tone at all times.

What is the difference between resonated and non-resonated?

A non-resonated system removes the mid-pipe resonator, resulting in a louder, more aggressive sound with less dampening.

Do I need a ECU remap after installation?

While not strictly required for a GPF-back exhaust, a remap can help you realize the full performance potential of the improved exhaust flow.

How do I claim the lifetime warranty?

The warranty applies to the original purchaser; keep your proof of purchase and contact the point of sale or Scorpion directly for service.

Troubleshooting

Exhaust rattling or vibration

Check all mounting hangers and ensure no part of the system is making contact with the vehicle chassis.

Exhaust tip misalignment

Loosen the clamp connections, adjust the rotation or depth of the tailpipes, and retighten while the system is cool.

Increased noise levels

This is a characteristic of non-resonated systems; check that all gaskets are properly seated to ensure no exhaust leaks are contributing to excessive sound.

Pros and Cons

Setup, Compatibility & Care

This system is designed as a direct replacement for the stock exhaust from the GPF back. Given the precision engineering, it is recommended to have this system installed by a qualified automotive technician to ensure all hangers and joints are correctly aligned to prevent rattling. To maintain the system, periodically inspect the mounting points and fasteners to ensure they remain secure. Clean the exhaust tips regularly with a non-abrasive metal polish to prevent carbon buildup and maintain the aesthetic finish of the stainless steel components.
