Borla 140909 Cat Back Exhaust System
The Borla 140909 is a S-Type Cat-Back exhaust designed to replace the factory system while preserving a refined, aggressive note. Its stainless steel construction emphasizes durability under daily driving and track use. The kit typically includes all required piping, bends, clamps, and a high-flow muffler configuration to improve exhaust flow without introducing excessive drone. Installers often appreciate Borla’s proven fit for BRZ models, with a tone that remains civil in everyday driving yet more pronounced under acceleration. Performance gains are generally associated with reduced backpressure and a freer exhaust path, contributing to a more engaging driving experience.
Invidia HS12SSTG3S Q300 Cat-Back for BR-Z/ FR-S
The Invidia Q300 HS12SSTG3S offers 60mm piping with a 101mm titanium rolled tip, designed for Subaru BR-Z/Scion FR-S platforms. This cat-back focuses on a balanced blend of flow and a pronounced upgrade in exhaust tone, often delivering a deeper growl without becoming intrusive in cabin resonance. The system typically features mandrel-bent tubing to minimize flow restrictions, with a stainless steel construction that resists corrosion. For BRZ owners seeking a recognizable, sporty note paired with reliable performance, this model is a popular choice.
MBRP 2022 BRZ 2.4L/GR86 2.4L Dual Split Axle Back
The MBRP Armor Pro Axle Back system for BRZ/GR86 combines a dual split outlet design with a 5-inch OD CF tip appearance. Built from T304 stainless steel, it emphasizes durability and an aggressive silhouette. The design seeks to maintain a balanced exhaust note—clear, raspy at higher RPMs but not overwhelming at cruising speeds. This option is well-suited for enthusiasts who want a performance-focused upgrade that complements the BRZ’s lightweight chassis with a modern, sporty exhaust voice.
Auto Dynasty J2 Engineering 4-Inch Round Muffler Back Axle Back
The Auto Dynasty J2 Engineering axle-back system is designed to maximize exhaust airflow while delivering a robust, racing-inspired tone. It uses high-quality stainless steel with mandrel-bent tubing and TIG-welded joints for added strength and corrosion resistance. Fitment covers Scion FR-S and BRZ models across multiple years, with careful attention to left-side installation. This option is notable for its emphasis on performance gains and a bold exhaust note that suits driving enthusiasts seeking an audible, sporty soundtrack without replacing the entire exhaust system.
Tomei Expreme Ti Type-80 Cat Back
The Tomei Expreme Ti Type-80 cat-back delivers a titanium construction designed for high strength-to-weight ratios and corrosion resistance. This system is often chosen by BRZ/FR-S owners seeking an ultra-lightweight upgrade with a refined, higher-end tone. Titanium reduces overall mass, which can contribute to slightly more responsive exhaust performance. The Type-80 designation commonly implies a slightly more aggressive note at high RPMs while maintaining a level of civility for street use. Fitment targets 2013+ BRZ/FR-S vehicles, aligning with modern aftermarket expectations for performance, durability, and lightweight design.
Buying Guide
- Fitment and compatibility: Ensure the exhaust is designed for BRZ/FR-S/GR86 families and matches your vehicle year and trim.
- Material and durability: Stainless steel is standard for longevity; titanium offers weight savings and a premium feel but at a higher price.
- Tone and drone: Consider whether you want a deep, aggressive tone or a more subtle growl. Some systems emphasize low-end torque, while others enhance high-RPM behavior.
- Flow characteristics: Cat-back and axle-back designs affect exhaust flow. Mandrel-bent tubing generally provides better flow than fixed bends.
- Installation: Some systems are bolt-on; others may require professional welding or additional hardware. Check included components and required tools.
- Weight considerations: Lighter exhausts can slightly improve throttle response and handling, particularly on lighter BRZ builds.
- Warranty and brand support: Reputable brands often provide clearer installation guidance and after-sale support.
- Aesthetic goals: Tip size, finish (stainless vs. titanium), and overall silhouette should align with your car’s styling cues.
- Noise regulations: Consider local noise ordinances and the potential for in-cabin drone at highway speeds.
- Budget balance: High-end titanium systems offer performance and weight benefits but at a premium; steel options provide solid performance at a lower cost.
