Product Information

Full details

The Scorpion Non-Resonated Cat Back Exhaust System is designed for automotive enthusiasts who prioritize a sportier exhaust note and improved engine responsiveness. This system delivers a significant aesthetic and performance upgrade over stock components through precision engineering and high-quality materials, though users should be aware that the non-resonated design creates a more aggressive, louder sound profile that may not suit those seeking a subtle daily driving experience.

FAQs

Is this exhaust street legal?

Yes, as it is a cat-back system that retains the vehicle's primary emissions components, it is designed to remain compliant with standard road regulations.

Does this system require a software tune?

While a tune can help maximize the performance benefits of a high-flow exhaust, this system is designed to function correctly with the factory engine management.

What is the difference between resonated and non-resonated?

A non-resonated system removes the sound-dampening resonator, resulting in increased exhaust volume and a more direct, aggressive tone compared to a resonated version.

Does the lifetime warranty cover everything?

The warranty covers defects in materials and craftsmanship for the original purchaser, provided the system was installed correctly.

Will this increase my car's fuel consumption?

Generally, performance exhausts do not negatively impact fuel economy when driving normally, though increased engine power potential may change driving habits.

Troubleshooting

Exhaust alignment feels off or touches the underbody

Loosen the mounting clamps, adjust the position of the mufflers and pipes for proper clearance, and re-tighten while ensuring hangers are under the correct tension.

Rattling noise during acceleration

Check all mounting bolts and clamps to ensure they are torqued to the correct specifications and confirm no components are vibrating against the vehicle chassis.

Valve system not switching modes

Verify that the valve actuator is correctly connected to the vehicle's electrical or vacuum source and check for any physical obstructions preventing the valve butterfly from moving.

Pros and Cons

Pros

  • Improved throttle response and power delivery
  • Distinctive, aggressive sport exhaust tone
  • High-grade T304 stainless steel construction
  • Valved design offers versatile sound modes
  • Durable build quality with a lifetime warranty

Cons

  • Non-resonated design may be too loud for some environments
  • Requires professional installation for best fitment
  • Noticeable sound increase compared to factory exhaust

Setup, Compatibility & Care

Installation of this system should be carried out by a qualified technician to ensure all joints are perfectly aligned and leak-free. As a cat-back system, it is designed to bolt onto the existing catalytic converter, maintaining full compliance with standard emissions hardware. To keep the system in top condition, periodically inspect the mounting hangers for wear and ensure the exhaust valves are free of debris or road salt buildup. While T304 stainless steel is highly corrosion-resistant, cleaning the tailpipes with a stainless steel polish will help maintain the black aesthetic finish over the life of the product.
