Downpipes

Do you own a turbocharged vehicle? Are you looking to level up its power and performance significantly? Private Label MFG (PLM) has the perfect downpipe to power up your need for speed.

Our performance turbo downpipes will help improve exhaust flow while optimizing boost consistency to help improve throttle response. Crafted with high-quality stainless steel, these downpipes are a must-have for any enthusiast looking to boost their vehicle’s performance on the streets.

Unlock More Power with Better Exhaust Flow

Our turbo downpipes are engineered to reduce exhaust restrictions, allowing gases to escape more efficiently. This means your turbo spools up quicker, delivering a noticeable boost in power and responsiveness. Whether you're accelerating on the highway or pushing limits on the track, smoother airflow helps you get the most out of your setup.

By optimizing exhaust flow, our downpipes help maintain consistent boost pressure, improving overall engine efficiency and power. The result is a sharper throttle response, increased horsepower potential with proper tuning, and an exhilarating driving experience.

Built to Last with Premium Stainless Steel

Crafted from high-quality stainless steel, our downpipes are built to withstand extreme heat and resist corrosion. Unlike lower-quality alternatives, our downpipes offer long-term reliability, ensuring your performance upgrades stay effective. Strong welds and precision construction mean you get a product that stands up to demanding conditions.

Upgrade with confidence, knowing you’re investing in parts that deliver both power and longevity.

Frequently Asked Questions

What is a downpipe, and what does it do?

A downpipe is a component in a turbocharged vehicle’s exhaust system that connects the turbocharger to the rest of the exhaust. The downpipe improves exhaust flow and enhances performance.

What is the difference between a catted and a catless downpipe?

The primary difference between a catted and a catless downpipe lies in the presence or absence of a catalytic converter. A **catted downpipe** incorporates a high-flow catalytic converter, which is designed to filter harmful emissions from your exhaust gases. This makes them generally compliant with emissions regulations in many regions and less likely to trigger a Check Engine Light (CEL) related to emissions. While they still offer significant performance gains over stock downpipes due to improved flow, the catalytic converter does introduce a slight restriction compared to a catless design.

A catless downpipe, on the other hand, completely removes the catalytic converter. This design offers the least restriction to exhaust flow, maximizing potential horsepower and torque gains, and often results in a more aggressive exhaust note. However, catless downpipes are intended for off-road or track use only, as they do not filter emissions and are illegal for street use in most areas. They will almost always trigger a CEL without an ECU tune specifically designed to suppress the O2 sensor readings. We offer both options to cater to different customer needs and intended vehicle use.

Will installing a catless downpipe make my car louder?

Yes, a catless downpipe removes the restrictive catalytic converter, resulting in a more aggressive exhaust sound compared to a catted option.

How can I confirm if a downpipe will fit my specific vehicle model and year?

Ensuring proper fitment is crucial for a smooth installation and optimal performance. To confirm if one of our downpipes will fit your specific vehicle model and year, we recommend a few steps. First, please utilize the vehicle selector tool available on our website; this allows you to filter products specifically designed for your make, model, and year. Second, carefully review the "Vehicle Fitment" section on each product page, as this will list all compatible vehicles, often including specific engine codes or chassis designations. If you have any doubts or your vehicle has unique modifications, we encourage you to contact our customer support team with your vehicle's full details, including the make, model, year, engine type, and VIN if possible. Our experts will be happy to assist you in finding the perfect downpipe for your application.

Will I need an ECU tune after installing one of your downpipes?

While it's possible to install a downpipe without an immediate ECU tune, we highly recommend one to unlock the full performance potential of your new downpipe and to ensure optimal engine operation. For **catless downpipes**, an ECU tune is almost always necessary to prevent a Check Engine Light (CEL) from illuminating due to the absence of the catalytic converter, which the factory O2 sensors are designed to monitor. For **catted downpipes**, while a CEL is less common, a tune will still optimize air-fuel ratios, boost pressure, and ignition timing to take full advantage of the increased exhaust flow, resulting in maximum horsepower and torque gains. Without a tune, your vehicle's ECU may not be able to properly adapt to the significant change in exhaust flow, potentially leading to suboptimal performance or even fault codes. We advise consulting with a reputable tuner to ensure your vehicle is properly calibrated after installation.

Do your downpipes include all the necessary gaskets and hardware for installation?

Yes, at Private Label Mfg, we strive to make installation as straightforward as possible. Our downpipes typically include all the necessary gaskets and hardware required for a direct bolt-on installation. This usually comprises high-quality gaskets for the turbo outlet and the connection to your mid-pipe, as well as bolts, nuts, and clamps (such as V-band clamps where applicable). Our goal is to provide a complete solution so you don't have to source additional components. We always recommend checking the specific product description for the downpipe you are interested in, as it will detail exactly what is included in the box.
