Factors to Consider When Choosing Cat Back Exhaust For Scion Fr S
Selecting the right cat back exhaust for your Scion FR-S involves balancing performance, sound, durability, and budget. I recommend considering your primary goal: Are you after a subtle upgrade, a significant performance boost, or a more aggressive sound? Think about how much weight reduction or power increase you desire, and whether installation complexity is a concern. The right choice depends on your driving style and how much you’re willing to invest in both parts and labor.
Performance vs. Sound
If you want more horsepower and torque, systems like Invidia and REV9 are designed to optimize flow and top-end power, often at the expense of increased noise. Conversely, if your goal is a refined, moderate sound upgrade, the Borla or the stainless steel axle back might be better suited, as they focus on durability and subtlety without sacrificing too much comfort.
Material and Durability
Stainless steel is the standard for longevity, resisting corrosion and maintaining appearance over time. The systems reviewed are all stainless steel, but quality varies—Invidia’s SUS304 is premium, while others may use similar grades. Heavyweight systems like Invidia might be more robust, but they can be more cumbersome to install. Lighter options like REV9 reduce weight but may be louder or less durable over long term.
Installation and Compatibility
Most systems are designed for direct bolt-on installation, but some, like Invidia, may require professional help, especially if the weight is substantial. Compatibility is key—ensure the system fits your model year and specific trim. For owners of 2012-2021 FR-Ss, options vary, so double-check the product details before purchasing to avoid fitment issues.
Frequently Asked Questions
Will upgrading my cat back exhaust improve my Scion FR-S’s performance?
Yes, upgrading to a high-quality cat back exhaust can improve exhaust flow, which often results in slight increases in horsepower and torque, especially at higher RPMs. However, the extent of gains depends on other modifications like intake and tuning. For noticeable performance improvements, pairing your exhaust upgrade with other tune or intake modifications will produce better results.
How loud will my car be with these exhaust systems?
The sound levels vary depending on the system. Systems like REV9 and Invidia tend to produce deeper, louder exhaust notes, which can be desirable for aggressive driving but may be too loud for daily use. Borla and the OEM replacement axle back are typically more subdued, suitable for owners who want a sporty tone without excessive noise. Always consider your comfort with loud exhausts before choosing a system.
Is professional installation necessary for these exhausts?
Most systems are designed for bolt-on installation, which can be done at home with basic tools. However, heavier or more complex systems like Invidia might benefit from professional installation to ensure proper fit and seal. If you’re not experienced with exhaust work, hiring a professional can help avoid issues like leaks or improper mounting, especially for systems with additional weight or complexity.
Will these exhaust systems affect my vehicle’s warranty?
Modifications like a cat back exhaust can potentially impact your vehicle’s warranty, particularly if they cause issues related to emissions or exhaust components. It’s wise to check your warranty terms and local regulations before installing aftermarket parts. Some manufacturers may void certain warranty aspects if the upgrade is deemed non-original or if it causes damage.
How do I choose between a full system and just an axle-back upgrade?
Choosing between a full system and an axle-back depends on your goals and budget. An axle-back like the stainless steel replacement is easier and cheaper but offers limited performance gains. A full system, such as those from Borla or Invidia, provides more significant flow improvements and power increases but at a higher cost and complexity. Consider whether you want a simple cosmetic change or a comprehensive upgrade for performance gains.
Conclusion
If you’re a casual driver or someone new to exhaust upgrades, the stainless steel axle back offers durability and simplicity. Performance enthusiasts will appreciate the Borla or Invidia systems for their power and flow improvements. For those seeking maximum performance and weight savings, REV9 delivers a deep tone along with handling benefits, though it might be too aggressive for daily driving. Ultimately, your choice should reflect your driving style, sound preference, and how much you’re willing to invest in your Scion FR-S’s exhaust system.
