Description
Upgrade the performance, sound, and appearance of your 2017–2020 Honda Civic Si Sedan (L4-1.5L Turbo) with the Takeda 3" to 2.5" Cat-Back Exhaust System. Precision-engineered from premium 304 stainless steel, this system is designed to deliver dyno-proven power gains, a deeper exhaust tone, and long-lasting durability for both street and spirited driving.
Premium Construction
Built from 3" to 2.5" mandrel-bent 304 stainless steel tubing, the Takeda cat-back system ensures smooth, unrestricted exhaust flow while resisting corrosion and discoloration over time. Each system is 100% hand-TIG-welded for exceptional strength and a high-end finish.
Performance Gains You Can Feel
On aFe’s in-house dyno, this exhaust system produced verified increases of up to +10 horsepower and +11 lb-ft of torque, giving your Civic Si improved throttle response and more engaging acceleration.
Aggressive, Refined Exhaust Note
Dual free-flowing 304 stainless steel mufflers are tuned to eliminate harsh high-pitch frequencies while delivering a deep, aggressive sound that enhances the driving experience without overwhelming cabin comfort.
Dual Carbon Fiber Exhaust Tips
The system is finished with dual 4.5" carbon fiber exhaust tips featuring 304 stainless steel inner construction and an etched aFe POWER logo. The large-diameter tips provide a premium motorsport look that perfectly complements the Civic Si’s rear design.
Easy, Hassle-Free Installation
Designed to utilize all factory mounting points, the Takeda cat-back system installs easily with no cutting or modifications required. OE-style bayonet hangers maintain precise pipe alignment and ensure long-term stability under all driving conditions.
