Description
2-1/2" 304 Stainless Steel Cat-Back Exhaust System. Engineered for enthusiasts who demand power and precision, this high-performance exhaust delivers proven gains, aggressive tone, and superior craftsmanship for long-term durability.
Proven Performance Gains
On the dyno, this Takeda system produced up to +10 horsepower and +11 lb-ft of torque, improving throttle response and overall engine efficiency. The 3" to 2.5" mandrel-bent stainless steel tubing reduces restriction, allowing the turbocharged 1.5L engine to breathe more freely.
Deep, Aggressive Exhaust Tone
Dual free-flowing 304 stainless steel mufflers help eliminate high-frequency tones while enhancing low-end depth, producing a clean, aggressive sound that complements the Civic Si’s sporty driving dynamics.
Black Dual Rear-Exit Stainless Steel Tips
This system features dual 4-3/4" x 4-1/2" oval, double-wall, angle-cut black stainless steel tips, each laser-etched with the Takeda logo. The bold exhaust finish adds a custom, premium look to the rear of the Civic Si.
