Abarth Downpipes – Performance, Catted & Decat Options for 500, 595 & Competizione

Abarth Downpipes – Unleash the True Sound and Power of Your Abarth

Abarth downpipes are one of the most effective upgrades for improving both the performance and sound of your car. By replacing the restrictive factory part, a performance Abarth downpipe maximizes exhaust flow, reduces turbo lag, and delivers aggressive sound that every enthusiast desires. Whether you drive an Abarth 500, Abarth 595 or the Abarth Competizione, installing the right downpipe takes your driving experience to a whole new level.

Why Upgrade to a Performance Abarth Downpipe?

The factory downpipe on an Abarth is designed with emissions and noise restrictions in mind, not performance. This means your turbocharged engine is not breathing freely. Upgrading to a performance Abarth downpipe comes with several benefits:

• More horsepower and torque – free-flowing design helps your turbo spool faster.
• Sharper throttle response – immediate reaction when you press the pedal.
• Deeper and sportier exhaust tone – from refined sport sound with catted downpipes to raw aggression with decat downpipes.
• Lower exhaust gas temperatures – reduced backpressure prolongs turbo life.
• Perfect for tuning – an Abarth downpipe combined with ECU remapping unlocks maximum gains.

Types of Abarth Downpipes

Depending on your setup, regulations, and personal preference, you can choose from several different types of Abarth downpipes:

Catted Abarth Downpipes

Catted downpipes use a high-flow sports catalytic converter to reduce emissions while still offering excellent performance gains. They are ideal for street-driven cars where legality and MOT compliance are required. Abarth drivers who want better flow without triggering engine lights often choose this option.

Decat Abarth Downpipes

Decat downpipes remove the catalytic converter completely, allowing maximum exhaust flow. They deliver the most horsepower and the most aggressive exhaust tone possible. This is the choice for Abarth owners who take their cars to the track or want an uncompromised motorsport sound. Please note: decat pipes are typically for off-road and race use only.

Sport Abarth Downpipes

Sport downpipes offer the perfect balance between performance and comfort. They usually feature increased pipe diameter, smoother bends, and sometimes a high-flow catalytic converter. Ideal for Abarth owners who use their cars daily but want noticeable performance improvements and a sportier tone.

Stainless Steel & Titanium Downpipes

Material is just as important as design. Stainless steel downpipes are the most popular choice thanks to their durability and resistance to corrosion. For those chasing every kilo and premium aesthetics, titanium downpipes provide extreme lightweight construction and a motorsport-inspired finish.

Abarth Models Supported

Our range of Abarth downpipes covers the most popular models, including:

• Abarth 500 Downpipes – compact performance gains for the legendary pocket rocket.
• Abarth 595 Downpipes – sportier tone and improved turbo response for the most popular Abarth.
• Abarth Competizione Downpipes – premium performance upgrade for the track-focused Competizione version.
• Abarth Esseesse Downpipes – unleash the full potential of limited edition models.

Choosing the Right Diameter

When selecting an Abarth downpipe, pipe diameter is crucial for balancing flow and fitment. The most common sizes include:

• 2.5-inch downpipes – perfect for lightly tuned Abarth 500 and 595 models.
• 3-inch downpipes – the go-to option for heavily tuned Abarths running ECU remaps, hybrid turbos or additional performance upgrades.

Performance Gains

The exact gains depend on whether you choose a catted or decat Abarth downpipe, as well as supporting mods. On average, you can expect:

• +10–20 HP with just the downpipe installed.
• +25–40 HP when combined with ECU tuning.
• Noticeably quicker turbo spool and reduced lag.
• A deeper, more aggressive exhaust note that makes every gear change exciting.

Build Quality

All Abarth performance downpipes are designed to withstand extreme heat and pressure. The best options feature:

• High-grade stainless steel or titanium construction.
• Precision TIG welding for maximum strength.
• Mandrel-bent tubing to ensure smooth exhaust flow.
• OEM-style flanges for direct bolt-on installation.

Tuning Potential

Installing an Abarth downpipe without a tune already delivers gains, but the full potential is unlocked with ECU remapping. A tuned ECU adjusts fueling, boost pressure, and ignition timing to match the freer exhaust flow. This means even more horsepower, torque, and sharper throttle response.

Daily Driving vs Track Use

Choosing between catted and decat downpipes depends on how you use your Abarth. For daily drivers who want performance without legal issues, catted downpipes are the best option. For track-focused builds, decat downpipes provide the ultimate flow and raw motorsport sound.

Abarth Downpipes in Motorsport

The Abarth brand has deep roots in motorsport, and performance upgrades like downpipes are part of that DNA. Many track builds and race-prepped Abarths use decat systems for maximum power and sound. Motorsport-grade stainless steel and titanium downpipes ensure reliability even under extreme racing conditions.

Conclusion

Upgrading your car with a high-performance Abarth downpipe is one of the most effective modifications for unlocking hidden power, reducing turbo lag, and achieving the aggressive exhaust tone that defines the Abarth spirit. Whether you prefer the street-friendly option of a catted downpipe or the uncompromised flow of a decat downpipe, our selection has the perfect solution for every Abarth enthusiast. From the 500 to the 595 and Competizione, there is no better way to unleash the true performance of your car.
