Frontpipe Back Exhaust

The 27WON Performance Frontpipe Back Exhaust is engineered to enhance the look and sound of your 2022+ Honda Civic Si or 2023+ Acura Integra 1.5T. This system is meticulously crafted from 100% T304 stainless steel, ensuring durability and corrosion resistance. Precision TIG welding is utilized throughout the construction, providing strong and reliable joints. The brushed finish adds a premium aesthetic that will maintain its appearance over time. This exhaust system features a two-phase resonator design, incorporating both an expansion chamber and an absorption resonator. This technology effectively manages exhaust gases, reducing back-pressure and increasing performance potential while delivering a deep, attention-grabbing growl. The dual 100mm polished tips, complete with signature logo plates, are designed to perfectly complement the vehicle's rear bumper. Performance is a key focus, with an increased exhaust piping diameter from 50mm to 63.5mm. This 58% increase in cross-sectional area reduces back pressure, allowing hot exhaust gases to exit more efficiently, supporting future power modifications and contributing to a satisfying exhaust note. The system utilizes 3-bolt flanges for optimal sealing and alignment during installation, a superior alternative to less reliable slip joints or 2-bolt flanges. Custom gaskets are included for a leak-free and long-lasting setup. Available in multiple configurations, including front-pipe back, cat-back, and full turbo-back systems, you can choose the sound level and performance gain that best suits your needs.
