Fiat 500 Downpipes – Catted and Decat Performance Exhaust Upgrades

( number of products: 2 )

Upgrade your Fiat 500 with high-performance downpipes. Choose from catted or decat options to enhance power, reduce turbo lag and improve exhaust sound.

Fiat 500 Downpipes – Unlock Your Abarth's True Potential

The Fiat 500 is a lightweight hatchback with an iconic design and a sporty character, especially in its Abarth versions. While stock performance is fun, the restrictive OEM downpipe limits exhaust flow, turbo spool and overall power delivery. Upgrading to a performance Fiat 500 downpipe is one of the most effective modifications to unleash hidden horsepower, reduce backpressure and give your car a motorsport-inspired exhaust tone.

Why Upgrade to a Performance Fiat 500 Downpipe?

The factory downpipe focuses on emissions compliance and noise reduction, which means sacrificing exhaust efficiency and turbo response. A high-flow Fiat 500 downpipe delivers several benefits:

  • More horsepower and torque – improved exhaust flow reduces backpressure and lets the engine breathe.
  • Faster turbo spool – enjoy quicker throttle response and better acceleration.
  • Enhanced exhaust sound – catted downpipes give a deeper tone, while decat downpipes deliver an aggressive motorsport roar.
  • Lower exhaust gas temperatures – improving durability during spirited driving and track sessions.
  • Perfect for ECU tuning – essential for Stage 1, Stage 2 and hybrid turbo setups.

Types of Fiat 500 Downpipes

Our range of Fiat 500 downpipes is engineered for various performance levels and driving styles:

Catted Fiat 500 Downpipes

Catted downpipes feature a high-flow sports catalytic converter that balances emissions compliance with improved performance. Ideal for daily drivers in regions with strict emissions testing.

Decat Fiat 500 Downpipes

Decat downpipes remove the catalytic converter entirely, maximizing flow and raw performance. Best suited for off-road, track-focused builds or areas without emissions restrictions.

Material Options: Stainless Steel and Titanium

The material you choose impacts weight, heat management and long-term durability:

  • Stainless steel downpipes – robust, corrosion-resistant and cost-effective.
  • Titanium downpipes – ultra-lightweight, superior heat resistance and a premium motorsport look.

Engine Compatibility

Our Fiat 500 downpipes are compatible with a wide range of petrol and Abarth engine configurations:

  • Fiat 500 1.2 Downpipes – optimized for naturally aspirated setups.
  • Fiat 500 1.4 T-Jet Downpipes – ideal for Abarth variants with turbocharged engines.
  • Fiat 500 0.9 TwinAir Downpipes – engineered for turbocharged twin-cylinder efficiency.
  • Fiat 500 Abarth Downpipes – designed specifically for high-performance models.
  • Fiat 500e Downpipes – not applicable for EV variants.

Performance Gains with Fiat 500 Downpipes

Switching from an OEM downpipe to a performance Fiat 500 downpipe delivers instant results:

  • +10–25 HP with a downpipe upgrade alone.
  • +30–50 HP when combined with Stage 2 ECU tuning.
  • Improved torque delivery across the rev range.
  • Sharper throttle response and reduced turbo lag.

Choosing the Right Diameter

Picking the correct downpipe diameter is crucial for maximizing gains:

  • 2.25-inch downpipes – ideal for lightly tuned engines and Stage 1 builds.
  • 2.5-inch downpipes – recommended for Stage 2 setups, hybrid turbos and aggressive tuning projects.

All our Fiat 500 downpipes are engineered for direct bolt-on installation, ensuring perfect fitment without cutting or welding.

Build Quality and Engineering

Our performance Fiat 500 downpipes are built to meet the highest standards:

  • Mandrel-bent tubing for smooth, unrestricted flow.
  • High-grade stainless steel or titanium construction.
  • Precision TIG welding for maximum strength and leak-free performance.
  • OEM-style flanges for seamless integration.

Tuning Potential

Pairing your Fiat 500 downpipe with ECU tuning unlocks the full performance potential:

  • Substantial power and torque gains.
  • Optimized turbo boost and fuel delivery.
  • Sharper throttle mapping and improved drivability.
  • Custom exhaust sound profiles depending on your catted or decat configuration.

Daily Driving vs Track Builds

For everyday street cars, catted downpipes offer a perfect balance between performance and emissions compliance. For track-dedicated setups, decat downpipes deliver maximum exhaust flow and an aggressive motorsport sound.

Conclusion

Upgrading to a performance Fiat 500 downpipe is one of the best ways to unlock hidden horsepower, reduce turbo lag and enhance exhaust acoustics. Whether you choose a catted downpipe for road compliance or a decat downpipe for ultimate track performance, our selection of Fiat 500 downpipes guarantees precision fitment, superior build quality and proven results.
