Description

ETS Recirculated Downpipe for Mitsubishi Evo X 2008–2015

Firstly, Buy the ETS recirculated downpipe for the 2008–2015 Mitsubishi Evo X. The ETS recirculated downpipe is a performance exhaust upgrade designed for the 2008–2015  Mitsubishi Lancer Evolution X. It replaces the factory turbocharger O2 housing and downpipe assembly with a design developed for improved exhaust flow and a more controlled exhaust note.

Manufactured by Extreme Turbo Systems (ETS), this downpipe features a recirculated wastegate dump. This design routes wastegate gases back into the exhaust stream instead of releasing them through a separate open dump. As a result, it helps maintain a more factory-like sound under wide-open throttle.

The downpipe is designed for Evo X owners who want to upgrade their turbo-back exhaust setup while keeping the wastegate flow integrated into the exhaust. Its CNC-machined tapered flange is shaped to match the turbocharger outlet, helping create a precise connection when correctly installed.

Benefits of the ETS Recirculated Downpipe

Upgrading the downpipe can be an important step in a modified Evo X exhaust build. The right component should balance exhaust flow, sound, fitment, and compatibility with the rest of the system.

Recirculated wastegate design

The defining feature of this downpipe is its recirculated wastegate arrangement. Instead of using an open external dump, it directs wastegate gases back into the exhaust.

This helps produce a more factory-like sound under wide-open throttle. It is a useful feature for drivers who prefer an integrated exhaust setup rather than the louder, more distinct sound associated with an open dump.

CNC-machined turbo flange

The tapered flange is CNC-machined to match the turbocharger outlet. Accurate flange alignment helps create a secure connection and supports smooth exhaust flow through the joint.

Correct installation remains essential. Check the mating surfaces, gasket placement, and fasteners before tightening the assembly.

Factory oxygen sensor location

The ETS downpipe retains the factory oxygen sensor location and includes a separate wideband sensor bung with a plug. This gives the installer designated sensor mounting points for a compatible setup.

Sensor placement does not guarantee that the vehicle will avoid a check-engine light. Results depend on the ECU calibration, sensor arrangement, and other exhaust modifications.

Designed for performance exhaust systems

The downpipe replaces the original O2 housing and downpipe assembly. It can be considered as part of a wider exhaust upgrade involving compatible components farther downstream.

Actual performance gains depend on the vehicle’s condition, turbocharger, tuning, and other modifications. Do not assume a specific horsepower increase without supporting test data for your exact configuration.

Mitsubishi Evo X Fitment and Compatibility

This ETS downpipe is listed for the 2008–2015 Mitsubishi Lancer Evolution X, which uses the turbocharged 4B11T 2.0-litre engine.

Before buying, verify the model year and the configuration of your existing exhaust. The product is designed to replace the factory O2 housing and downpipe, so it is not a universal component for every Mitsubishi Lancer Evolution.

Pay particular attention to steering configuration. The supplier notes that the downpipe may not fit right-hand-drive vehicles. If your Evo X is right-hand drive or has a modified turbo setup, confirm compatibility with ETS or the seller before placing an order.

You should also check how the downpipe connects to your remaining exhaust components. Aftermarket exhaust systems can differ in their connection points, so confirm compatibility rather than assuming every combination will bolt together.

Installation and Important Buying Considerations

A correct installation helps prevent exhaust leaks, poor alignment, and contact with nearby components.

Firstly, allow the exhaust and turbocharger to cool completely before starting work. Secondly, inspect the flange surfaces, gaskets, studs, and sensor ports before fitting the downpipe. Thirdly, secure all connections according to the appropriate service instructions and check for leaks after installation.

Professional installation is recommended if you do not have the tools or experience to work safely around a turbocharger and exhaust system.

Important: ETS and retailer listings identify this product as for off-road use only. Check applicable emissions regulations and vehicle-use requirements before purchasing. Do not assume it is approved for public-road use simply because it fits the vehicle.

The manufacturer also notes that the warranty is void on wrapped or coated downpipes. If you intend to apply a heat wrap or coating, review the warranty terms before modifying the product.

Frequently Asked Questions

What vehicles does the ETS recirculated downpipe fit?

It is listed for the 2008–2015 Mitsubishi Lancer Evolution X. Verify your vehicle’s model year, steering configuration, and existing exhaust setup before ordering.

What does a recirculated wastegate design do?

It routes wastegate gases back into the exhaust stream rather than releasing them through an open dump. This helps maintain a more factory-like exhaust sound under wide-open throttle.

Does the downpipe replace the factory O2 housing?

Yes. It is designed as a direct replacement for the factory O2 housing and downpipe assembly.

Does the package include installation hardware?

Supplier listings specify a stud, nut, turbine housing gasket, and exhaust gasket. They also instruct installers to reuse the factory studs where applicable. Confirm the package contents before purchase.

Can I use this downpipe on a right-hand-drive Evo X?

Fitment is not guaranteed. The supplier notes that it may not fit right-hand-drive vehicles, so check with the seller before ordering.

Will this downpipe increase horsepower?

It is designed to support a performance exhaust setup, but the actual result depends on the turbocharger, engine modifications, ECU calibration, and remaining exhaust components. No specific power gain should be assumed without testing.

Is the ETS downpipe legal for street use?

The product is listed for off-road use only. Check local emissions and road-use regulations before purchasing or installing it.

What is the part number?

The ETS part number is 100-10-EXH-001. Use this number when checking compatibility or asking a supplier about the product.
