The exhaust system is where your build comes together, and nowhere is the difference between stock and aftermarket more immediately felt and heard. An upgraded exhaust delivers improved flow, a more aggressive tone, and a cleaner finished look that sets your car apart. Whether you're building a street-focused daily driver or a dedicated track machine, the right exhaust setup makes a difference on every run.
This collection covers the full exit side of your exhaust system (cat-back systems, axle-back kits, performance mufflers, and exhaust tips), all hand-selected from brands trusted by the enthusiast community.
What's in This Collection?
Cat-Back Exhaust Systems
A cat-back system replaces everything from the catalytic converter back to the tip. It's the most comprehensive bolt-on exhaust upgrade available and typically delivers the most noticeable improvement in both sound and flow. Cat-back systems are the go-to choice for builders who want a complete, cohesive exhaust solution that connects directly to an upgraded downpipe or mid-pipe.
Axle-Back Exhaust Systems
An axle-back system replaces the section of exhaust from the rear axle to the tip. It's a more targeted upgrade, ideal for improving exhaust tone and aesthetics without changing the full mid-section. Axle-backs are a popular entry point for enthusiasts who want to improve their vehicle's sound profile while keeping the install simple.
Performance Mufflers
The muffler plays a direct role in how your car sounds. Factory mufflers are designed to suppress as much noise as possible, often at the expense of flow. Aftermarket performance mufflers are built to balance sound character with exhaust efficiency, giving you that clean, purposeful tone without unnecessary drone.
Exhaust Tips
Sometimes it's about the details. Performance exhaust tips add a polished, finished look to the rear of your build. Available in a variety of finishes (including polished stainless, matte black, and dual-tip configurations), they're among the easiest ways to clean your car's exterior.
Brands You Can Trust
This collection features products from established names in the performance exhaust space, including
Milltek Sport, Thermal R&D, 27WON Performance, and DC Sports, all carefully selected for quality, fitment accuracy, and real-world performance on turbocharged import platforms.
Build a Complete Exhaust System
For the best results, pair your exhaust system with supporting upgrades from the full Exhaust Upgrades lineup. Start with a high-flow downpipe or J-pipe, connect through a performance frontpipe or mid-pipe, and finish it off with a cat-back or axle-back system from this collection. Finish the build with a supporting tune to ensure your ECU is optimized for the full setup.
Frequently Asked Questions
What's the difference between a cat-back and an axle-back exhaust?
A cat-back replaces everything from the catalytic converter back (including the mid-pipe, muffler, and tip) for a full system upgrade. An axle-back only replaces the section from the rear axle to the tip, making it a simpler, more affordable option focused primarily on sound and aesthetics.
Will an aftermarket exhaust increase horsepower?
Yes, particularly on turbocharged vehicles. Reducing exhaust restriction allows the engine and turbo to breathe more freely, resulting in measurable gains in horsepower and torque, especially when paired with a proper tune.
Do exhaust tips affect performance or just looks?
Exhaust tips are primarily a cosmetic upgrade. Performance gains come from the muffler, piping diameter, and overall system design, not the tip itself. That said, some tip designs can slightly influence exhaust sound character.
