Description
Upgrade your 2017–2020 Honda Civic Si sedan with the Takeda 2-1/2" 304 Stainless Steel Cat-Back Exhaust System—engineered to deliver improved performance, refined sound, and long-lasting durability. Designed and manufactured by aFe POWER in Corona, California, this premium exhaust system provides measurable power gains and a noticeable enhancement in driving dynamics.
Built from 2-1/2" mandrel-bent 304 stainless steel tubing, the system ensures maximum exhaust flow, corrosion resistance, and exceptional structural strength. On our in-house dyno, it demonstrated gains of up to +3 horsepower and +5 lb-ft of torque, giving your Civic Si sharper throttle response and improved acceleration.
A high-flow stainless steel muffler creates a deep, sporty exhaust note without unwanted drone, while the dual 4-1/2" polished 304 stainless steel clamp-on tips—complete with laser-etched Takeda logos—add a clean, aggressive finishing touch to the rear of your vehicle.
Installation is designed to be straightforward and hassle-free. With its factory-style flange and hangers, this cat-back system bolts directly to your OEM components with no cutting or modifications required. All necessary hardware is included for a smooth and secure fit.
Performance is further enhanced through an integrated mitered merge collector, engineered to reduce flow turbulence and increase exhaust velocity, resulting in improved horsepower, torque, and throttle response. Each system is 100% MIG-welded for race-proven durability and precise, long-lasting construction.
This exhaust system is designed using advanced computer-aided design (CAD) technology, ensuring high-accuracy fitment and optimal performance for your Honda Civic Si.
