For owners of the 2022 Honda Civic Si looking to amplify their driving experience, the 27WON performance exhaust system delivers a bold new sound and enhanced aesthetics. Designed specifically for the FE1 chassis of the 11th generation Civic Si and the DE4 Acura Integra, this system elevates your vehicle’s presence and performance. Available as a front-pipe back system or a complete turbo back exhaust, 27WON offers the perfect upgrade to match your style and performance goals.
Unleash a Refined and Aggressive Exhaust Note for Your Civic Si
The 27WON exhaust system is engineered to strike the perfect balance between a refined, sporty tone during normal driving and an aggressive growl when you demand peak performance from your 2022 Civic Si. The dual exit system is designed with two phase resonators, strategically placed to ensure a clean, deep sound profile while effectively minimizing unwanted frequencies. This innovative system uses both an expansion chamber resonator and an absorption resonator, resulting in reduced back-pressure and maximized performance potential for your Civic Si. For those seeking an even louder and more assertive exhaust note, the single exit version features a single resonator, delivering a more pronounced growl.

Dual or Single Exit: Tailor Your Civic Si’s Look
Choose the exhaust tip configuration that best complements your personal style and the aesthetic of your 2022 Civic Si. The dual exit option maintains a sophisticated, OEM-inspired appearance with two 100mm polished tips, subtly branded with the signature 27WON logo. These tips enhance the premium feel of your Civic Si while respecting its original design. Alternatively, the single exit system makes a bolder statement with a large 115mm (4.5”) tip, offering a tuner-inspired look that is sure to turn heads. Both tip options are crafted from the same high-quality stainless steel as the rest of the system and are designed for perfect integration with the Civic Si bumper cutout.

Enhanced Performance Through Increased Exhaust Flow
A key aspect of unlocking your 2022 Civic Si’s performance potential is optimizing exhaust flow. The 27WON exhaust system significantly improves upon the factory system by increasing the piping diameter from 50mm to 63.5mm. This increase in diameter results in a 58% greater cross-sectional area, substantially reducing back pressure. By allowing exhaust gases to exit the turbocharger more efficiently, this upgrade not only supports current performance but also accommodates future power modifications for your Civic Si. This enhanced flow also contributes to a deeper, more resonant exhaust tone.

Choose Your Volume: Front-Pipe Back or Turbo Back for Your Civic Si
The 27WON exhaust system for the 2022 Honda Civic Si offers versatility in sound level and performance enhancement through different configuration options. You can select a front-pipe back system, which includes a 2.5″ high-flow front pipe for a noticeable increase in volume and flow. For maximum performance gains and a more aggressive sound, opt for the full turbo-back exhaust system, complete with an 80mm high-flow catted downpipe. This modular design allows you to customize your exhaust system to perfectly match your desired sound and performance level.

Included custom gaskets further guarantee a leak-free system that will endure.
