Downpipe Buying Guide

A Key Section in a Turbocharged Exhaust System

The downpipe connects directly to the turbocharger and routes exhaust gases into the rest of the exhaust system. It is one of the first exhaust components downstream of the turbo.

Because of its position, the design of the downpipe influences how exhaust gases move away from the turbo and into the remaining exhaust path.

What Drivers May Observe

More consistent exhaust flow downstream of the turbocharger

Reduced restriction compared to some factory exhaust layouts

Smoother boost delivery under certain operating conditions

Changes in exhaust tone, depending on system setup

Catted vs Catless

Catted Downpipe

Includes a catalytic converter designed for specific applications
Used where emissions considerations or regulations apply
Often selected for vehicles intended for street use, where permitted

Catless Downpipe

Does not include a catalytic converter
Typically intended for off-road, competition, or export use
Used in applications where different regulatory standards apply

Is a Downpipe Right for Your Build?

Own a turbocharged vehicle

Are upgrading intake, intercooler, or exhaust components

Want improved exhaust efficiency and response

Are building a balanced street or track setup

Downpipe FAQs

What is a downpipe? +

A downpipe is the exhaust section that connects to the turbocharger and routes exhaust gases toward the rest of the exhaust system. Depending on the vehicle and product design, an upgraded downpipe may help reduce exhaust restriction and support improved turbo response when paired with the right setup.

What's the difference between catted and catless downpipes? +

A catted downpipe includes a catalytic converter, while a catless or racing downpipe does not include one and may alter or remove emissions-related equipment. Catless or racing downpipes are generally intended for off-road, racing, or closed-course use where emissions laws apply. Always check the product details and local regulations before purchase.

Will a downpipe increase horsepower? +

A downpipe may support improved exhaust flow and power potential when combined with proper tuning and supporting modifications. Horsepower and torque gains are not guaranteed and will vary depending on the vehicle, engine condition, tune, fuel, turbo setup, and overall exhaust system.

Do downpipes make the vehicle louder? +

A downpipe can change exhaust tone and may increase turbo or exhaust sound depending on the vehicle, whether the downpipe is catted or catless, and the rest of the exhaust system. Final sound level varies by setup.

Do I need tuning after installing a downpipe? +

Tuning requirements depend on the vehicle, downpipe design, emissions equipment, O2 sensor setup, and supporting modifications. Some applications may require compatible tuning or calibration to support drivability and reduce the chance of warning lights or engine codes.

Will a downpipe trigger a check engine light? +

It may, depending on the vehicle, catalytic converter configuration, O2 sensor location, and ECU calibration. Catless or racing downpipes are more likely to require supporting calibration or sensor-related solutions. Always verify the product notes and tuning requirements before installation.

Are downpipes street legal? +

Street legality depends on the downpipe design, emissions equipment, vehicle application, and local regulations. Catless, racing, or emissions-altering downpipes are generally intended for off-road, racing, or closed-course use where emissions laws apply and are not represented as street legal unless explicitly stated.

Can I use a downpipe with my stock exhaust system? +

Compatibility with a stock exhaust system depends on the vehicle and the specific downpipe design. Some downpipes are designed to connect to factory-style exhaust sections, while others may require compatible aftermarket exhaust parts, adapters, clamps, gaskets, or fabrication. Always check the product fitment and installation notes before ordering.

Are downpipes hard to install? +

Installation difficulty varies by vehicle. Some applications require tight access around the turbocharger, O2 sensors, heat shields, transmission area, or underbody. Rusted factory hardware and limited clearance can also increase installation difficulty. Professional installation is recommended.

Will a downpipe affect reliability? +

Reliability depends on product fitment, installation quality, tuning or calibration, heat management, sensor placement, gasket sealing, fastener condition, and the vehicle’s overall condition. Incorrect installation or mismatched tuning may cause drivability issues.

What should I verify before buying a downpipe? +

Verify your year, make, model, engine, turbo setup, emissions configuration, catalytic converter requirements, O2 sensor layout, flange or clamp connection, exhaust compatibility, and any tuning or calibration needs before purchase.
