Extreme Turbo Systems

What are the best turbo system upgrades for a 2022+ WRX? Extreme Turbo Systems (ETS) covers the full airflow path with a matched set of parts: a high-flow intake, titanium intake and charge pipe options, a top-mount intercooler, a GESI catted downpipe, and an axle-back exhaust. Together they reduce restriction and heat from the turbo to the tailpipe — check your year and model before ordering.

ETS — Extreme Turbo Systems — specializes in fabricated intake, intercooler, downpipe, and exhaust components for turbocharged cars, and this collection is built around its deep 2022+ WRX lineup. The lineup starts at the intake, flows through titanium charge piping and the top-mount intercooler, then exits through a GESI high-flow catted downpipe and an axle-back exhaust with multiple configuration options. Each piece is designed around the FA24 turbo platform, so the parts work as a coordinated system rather than a mix of mismatched designs.

Pair these parts with supporting cooling and airflow upgrades: browse our performance intercoolers, cold air intakes, cat-back exhausts, and the cooling collection for radiators and related heat-management parts.

About the Brand

Extreme Turbo Systems (ETS) has earned its following by focusing on fabricated turbo performance parts — intakes, intercoolers, downpipes, charge pipes, and exhausts — engineered for specific turbocharged platforms rather than universal fitment. Its reputation in the turbo Subaru community rests on parts like the 22+ WRX intake and top-mount intercooler systems carried here: carefully routed piping, quality welds and couplers, and premium options such as titanium intakes and charge pipes for buyers chasing weight savings and heat resistance. ETS also offers a GESI catted downpipe for the 2022+ WRX — a high-flow catalytic converter option for drivers who want downpipe performance with emissions equipment in place.

Frequently Asked Questions

Do I need a tune with an ETS intake or downpipe?

Anything that changes intake airflow or exhaust backpressure should be paired with ECU calibration. Talk to your tuner about a map or pro tune for your combination before driving hard.

What is a GESI catted downpipe?

A GESI catted downpipe uses a GESI high-flow catalytic converter in place of the factory cat. It flows better than stock while keeping catalytic converter equipment in the exhaust path — a popular middle ground between a catless pipe and the factory downpipe.

Why titanium for intakes and charge pipes?

Titanium saves weight over steel and resists heat well, which helps keep intake charge temperatures in check. It costs more than aluminum or steel equivalents, so it suits buyers prioritizing weight and appearance.

Axle-back vs. full cat-back — which do I need?

An axle-back replaces everything behind the rear axle for sound and looks with minimal change to flow; a cat-back replaces the system from the catalytic converter back. ETS offers the axle-back here — pair it with a downpipe and front pipe for a complete system.
