Turbo Back Exhausts Performance Parts & Modifications

Is your Subaru WRX or STi held back by a restrictive factory exhaust? Do you crave that deep, aggressive boxer rumble and extra horsepower? A high-quality turbo back exhaust system could be the upgrade you need.

At Empire Performance, we offer premium turbo back exhausts designed to maximise flow, boost performance, and deliver that iconic Subaru sound.

Why Upgrade to a Turbo Back Exhaust?

The factory exhaust on a Subaru WRX or STi is built to meet emissions and noise regulations, not performance. Stock systems often feature narrow piping, restrictive catalytic converters, and mufflers that stifle power and sound.

A turbo back exhaust replaces everything from the turbocharger outlet to the tailpipe. This includes the downpipe, mid-pipe, and rear muffler section. By eliminating restrictions, your engine breathes easier, unlocking horsepower and torque while enhancing throttle response.

Our High-Performance Turbo Back Exhaust Systems

Our 3" stainless steel turbo back exhausts are built for Subaru WRX and STi models, including GC8, GF8, GDA, GDB, and GG chassis.

• 3" mandrel-bent piping – Maximises exhaust flow for better performance.
• 304-grade stainless steel – Resists corrosion and lasts longer than mild steel.
• TIG welding – Ensures strong, leak-free joints.
• Straight-through design – Reduces backpressure for increased power.
• No catalytic converter (catless) – Improves flow, but check local emissions laws.

The Sound You’ve Been Missing

One of the biggest benefits of a turbo back exhaust is the sound. The Subaru boxer engine is famous for its deep, rumbling exhaust note, but the factory system muffles it.

Our exhausts bring out that aggressive rally-car tone while keeping drone to a minimum. Whether you’re cruising or pushing hard, you’ll love the way your WRX or STi sounds.

Bolt-On Performance Gains

Installing a turbo back exhaust is one of the most effective ways to boost power on a turbocharged Subaru. With fewer restrictions, the turbo spools faster, and the engine can breathe more efficiently.

Many customers report noticeable gains in throttle response and mid-range torque. Paired with a tune, the difference is even greater.

Built to Last

Cheap exhausts rust, crack, or fail over time. Ours are made from high-quality 304 stainless steel, which stands up to heat, moisture, and road debris. The TIG-welded construction ensures durability, while the mandrel-bent piping maintains smooth airflow.

Easy Installation & Fitment

Our turbo back exhausts are designed as direct bolt-on replacements for Subaru WRX and STi models. They include all necessary gaskets and hardware for a hassle-free install.
