Product Information

Full details

This Scorpion Large Bore Downpipe with De Cat is designed for performance enthusiasts looking to extract more power and enhance the exhaust sound of their VW Golf GTI (MK7) or Seat Leon Cupra (5F). It directly replaces the restrictive OE catalytic converter, offering significant performance gains and a sportier exhaust note, but it requires a remap and is not legal for road use in many regions. Key features include a large bore design for optimized airflow, robust construction with a lifetime warranty, and straightforward installation.

FAQs

What is a 'de-cat' downpipe?

A 'de-cat' downpipe is a performance exhaust component that replaces the factory catalytic converter with a straight pipe or a high-flow catalytic converter. This specific Scorpion product is a 'de-cat' pipe, meaning it removes the catalytic converter entirely for maximum flow.

Is this downpipe legal for road use?

No, in most regions with emissions regulations (like the UK), a vehicle fitted with a de-cat pipe will not pass road legality tests and is illegal for use on public roads. It is intended for off-road or track use only.

Do I need to remap my car after installing this downpipe?

Yes, a remap is essential. Without it, the ECU will likely detect the changes in exhaust gas flow and trigger a Check Engine Light, potentially causing drivability issues.

What kind of performance gains can I expect?

Gains vary depending on the vehicle and other modifications. However, this downpipe, when combined with a suitable remap, is designed to significantly increase horsepower and torque by improving exhaust flow.

What does the lifetime warranty cover?

Scorpion offers a lifetime warranty against anti-corrosion and manufacturing defects for the original purchaser, provided the exhaust is fitted to the vehicle for which it was intended.

How difficult is the installation?

It is designed for direct fitment and includes necessary hardware. However, due to the technical nature of exhaust systems and the requirement for a subsequent remap, professional installation by a qualified mechanic is highly recommended.

Will this change the sound of my exhaust?

Yes, removing the catalytic converter typically results in a louder, sportier, and more aggressive exhaust note.

Troubleshooting

Check Engine Light (CEL) illuminates after installation.

This is expected due to the removal of the catalytic converter. A professional ECU remap is required to correctly tune the engine management system and suppress the fault codes.

Exhaust leak detected at the connection points.

Ensure all clamps and gaskets are properly fitted and torqued. Double-check alignment during installation. If the issue persists, contact a qualified installer or Scorpion support.

Vehicle fails emissions test.

This product is a de-cat pipe and will not pass an emissions test requiring a functional catalytic converter. It is not legal for road use in most regulated areas.

Unexpected engine performance issues (rough running, poor power).

Confirm that an appropriate ECU remap has been performed by a reputable tuner. Incorrect tuning or a lack of remap can cause drivability problems.

Pros and Cons

Pros

  • Significant power and torque gains.
  • Produces a more aggressive and desirable exhaust note.
  • High-quality construction backed by a lifetime warranty.
  • Designed for straightforward installation.
  • Essential component for achieving higher performance tune levels.

Cons

  • Not legal for use on public roads in regions with emissions testing (e.g., UK MOT).
  • Requires an ECU remap to function correctly and avoid error codes.
  • May void vehicle warranty if installed improperly or used illegally.
  • Increased noise levels may not be desirable for all drivers.
  • Performance gains are maximized when combined with other upgrades and tuning.

Setup, Compatibility & Care

Compatibility:

This Scorpion Large Bore Downpipe is specifically designed for the VW Golf GTI (MK7) and Seat Leon Cupra (5F). Always confirm fitment for your specific vehicle model and year.

Installation:

Installation involves replacing the existing OE catalytic converter. The downpipe includes all necessary fittings and gaskets for a direct fit onto the turbocharger. However, it is strongly recommended that installation is performed by a qualified mechanic experienced with performance exhaust systems.

Post-Installation Requirements:

A significant caveat is that fitting this de-cat pipe *will* require an ECU remap. The vehicle's Engine Control Unit (ECU) relies on sensors (like lambda sensors) in the exhaust system to gauge engine performance and emissions. Removing the catalytic converter alters the readings these sensors provide, which will typically trigger engine warning lights and may lead to inefficient running. A remap recalibrates the ECU to work with the new exhaust flow, optimizing performance and preventing error codes.

Legal Considerations:

This de-cat pipe is intended for off-road, track, or competition use only. In many regions, including the UK, fitting a de-cat pipe will cause the vehicle to fail an emissions test, rendering it illegal for use on public roads. Ensure you are compliant with local regulations before installation and use.

Care:

Scorpion exhausts are known for their durability. The downpipe is made from high-quality materials and comes with a lifetime anti-corrosion warranty for the original purchaser. No special cleaning is typically required beyond standard vehicle maintenance. Periodically check all connections for security.
