Description
Enhance the performance, sound, and overall driving experience of your 2017–2020 Honda Civic Si Sedan with the Takeda 2-1/2" 304 Stainless Steel Cat-Back Exhaust System from aFe POWER. Engineered with precision and built from premium materials, this system delivers dyno-proven gains and a deeper, more aggressive exhaust tone—all while maintaining excellent durability and OEM-like fitment.
Constructed from 2-1/2" mandrel-bent 304 stainless steel tubing, this cat-back system maximizes exhaust flow to improve engine efficiency and long-term corrosion resistance. On aFe’s in-house dyno, it produced up to +3 horsepower and +5 lb-ft of torque, giving your Civic Si a noticeable bump in performance and responsiveness.
A high-flow stainless steel muffler delivers a refined yet sporty exhaust note, while the system is finished with dual 4-1/2" polished 304 stainless steel clamp-on tips, each laser-etched with the Takeda logo for a premium, eye-catching look. Designed to complement the Civic Si’s sporty styling, these tips provide both aesthetics and durability.
Installation is effortless thanks to a factory-style flange and hanger system, offering a true direct bolt-on experience with no cutting, modifications, or special tools required. All necessary hardware is included for a smooth and secure installation.
Performance is further optimized through an integrated mitered merge collector, engineered to reduce turbulence and increase exhaust velocity. This results in improved throttle response, horsepower, and torque—ideal for spirited street driving or track use.
Every Takeda exhaust system is designed using state-of-the-art computer-aided design (CAD) to ensure perfect fitment and consistent quality. The system is 100% MIG-welded, ensuring maximum strength, reliability, and long-lasting durability under high-heat conditions.
