GReddy 20172021 10th Gen Honda Civic SI Coupe Supreme SP Exhaust

GReddy Supreme SP Exhaust System for 2017-2020 Honda Civic Si Coupe ??

Take your Honda Civic Si Coupe to the next level with the GReddy Supreme SP Exhaust System, designed to deliver both performance and style. This cat-back exhaust system is engineered for the 2017-2020 Civic Si, offering a perfect blend of aggressive sound, improved performance, and high-quality construction. Whether you're cruising on the highway or pushing your car to the limit, this exhaust system ensures you enjoy every moment behind the wheel.

Aggressive Yet Refined Sound ??

The GReddy Supreme SP is all about enhancing the driving experience with a powerful, yet refined exhaust note. The deep, resonant tone is achieved through a combination of a straight-through muffler and resonator, which work together to minimize unwanted drone while amplifying the engine's natural sound. This exhaust delivers a strong, sporty tone that complements the turbocharged engine of the Civic Si, giving you that extra edge in both sound and performance.

Performance-Driven Design ?️?

This exhaust system is not just about sound—it's designed with performance in mind. The 76mm (3.0") piping optimizes exhaust flow, reducing backpressure and allowing your engine to breathe more freely. This results in improved throttle response and potential gains in horsepower and torque. The cat-back design ensures that this system bolts on directly to your existing setup without the need for any additional modifications, making it a straightforward upgrade.

High-Quality Construction ??

Crafted from premium stainless steel, the GReddy Supreme SP is built to last. The use of stainless steel ensures resistance to rust and corrosion, even in harsh weather conditions. The mandrel-bent piping maintains consistent diameter throughout, which is crucial for maintaining optimal exhaust flow. The system also features dual polished tips that not only look great but are also designed to withstand the rigors of daily driving.

Stylish and Functional Appearance ✨?

In addition to its performance benefits, the GReddy Supreme SP also adds a touch of style to your Civic Si. The dual polished exhaust tips give the rear of your vehicle a clean, aggressive look. The tips are positioned to perfectly complement the Civic Si's rear bumper design, creating a cohesive and sporty appearance. This exhaust system is the perfect combination of form and function, making it an ideal upgrade for any Civic Si owner.

Easy Installation ??

Installation is a breeze with the GReddy Supreme SP. The system is designed to be a direct bolt-on replacement for your factory exhaust, using the existing mounting points. This means no cutting, welding, or additional modifications are required, allowing you to enjoy the benefits of your new exhaust system in no time.
