Cobb 11-21 Subaru WRX/STI GV/VA Sedan Catback Exhaust 515160

COBB Stainless Steel Cat-Back Exhaust – WRX / STI Sedan (2011-2021)

Give your Subaru the voice it deserves. The COBB Stainless Steel Cat-Back Exhaust unlocks a deep, refined tone and smooth power delivery without turning your car into a drone machine. Crafted from high-grade stainless steel and built with precision TIG welds, this system is all about quality, fitment, and sound that feels OEM+ just meaner.

Key Features

• 100% 304 stainless steel construction for long-term durability
• Precision TIG-welded seams and cast flanges for perfect fit and leak-free performance
• 3" main tubing with a custom Y-pipe that splits into dual 2.5" legs for smooth, balanced flow
• COBB mufflers with dual 3.5" slash-cut tips finished with laser-etched COBB logos
• Includes multi-layer steel gaskets for a complete, ready-to-install setup

Sound That Speaks for Itself

This exhaust hits that sweet spot between aggressive and refined. Under throttle, you’ll hear a deep, throaty growl that actually matches the performance of your WRX or STI. Back off, and it quiets down enough for daily driving without the highway drone. It’s a tone that feels engineered, not just loud for the sake of being loud.

Built for Enthusiasts

Every part of this system is designed to bolt right up with no cutting, no guessing, and no hassle. The fitment is dead-on for 2011-2021 WRX and STI sedans, giving you a clean, factory-like install with an aftermarket edge. You’ll spend less time wrenching and more time driving.

Why We Like It

COBB nailed it with this one. The craftsmanship, the tone, and the fitment make this one of the best “install-it-and-forget-it” exhausts you can run. It’s performance that you can hear, feel, and trust all wrapped in that signature COBB build quality.
