If you’re a Subaru enthusiast, you know that performance is about more than speed. It’s about sound, efficiency, and the driving experience. One of the most effective ways to boost your Subaru’s performance is by upgrading to a Subaru WRX STI cat back exhaust system. At Custom Exhausts Birmingham, we specialise in delivering tailor-made exhaust solutions that improve your ride in both power and presence.
Why Choose a Cat Back Exhaust for Your Subaru WRX STI?
A cat back exhaust system replaces everything from the catalytic converter to the tailpipe. It’s a popular upgrade for performance-focused drivers for several compelling reasons:
Key Benefits:
- Improved Engine Performance: Less restrictive piping allows for better exhaust flow, reducing back pressure and improving extra horsepower.
- Enhanced Sound: A deep, aggressive tone that brings your Subaru WRX STI to life without being overly loud or droning.
- Fuel Efficiency Gains: Optimised airflow can lead to better fuel economy under normal driving conditions.
- Aesthetic Appeal: Polished tailpipes and clean welds add a sleek visual touch to the rear of your vehicle.
- Long-Term Durability: High-grade stainless steel options resist corrosion and are built to last.
What Makes the Subaru WRX STI Cat Back Exhaust Stand Out?
The Subaru WRX STI is already a performance powerhouse, but a custom cat back exhaust system takes it even further. Here’s what sets it apart:
- Precision Fitment: Designed specifically for the WRX STI, ensuring a perfect fit and clean integration.
- Performance Sound Tuning: Achieves a powerful yet refined sound profile tailored to the boxer engine’s unique characteristics.
- Increased Torque and Throttle Response: Especially noticeable in the low to mid RPM range for an even more exciting drive.

Frequently Asked Questions
Will a cat back exhaust void my warranty?
In most cases, a cat back exhaust won’t affect your manufacturer warranty, but it’s always best to check with your dealer.
Do I need a remap after fitting a new exhaust?
Not necessarily, but pairing your new exhaust with an ECU remap can help you make the most of your performance gains.
Is it road legal in the UK?
Yes, as long as your cat back exhaust system complies with noise regulations and doesn’t remove or bypass the catalytic converter.
