For enthusiasts of the new generation Honda Civic Si and Acura Integra (2022+ FE1/DE4 chassis), 27WON presents a groundbreaking exhaust system designed to amplify both aesthetics and auditory experience. Staying true to a refined aesthetic with its dual-tip configuration, this system significantly elevates the auditory presence, delivering a commanding growl that demands attention. Alternatively, for those seeking a more pronounced tuner-inspired look, a single exit option culminates in a robust 4.5” tip. Crafted entirely from premium T304 Stainless steel and meticulously TIG welded throughout, the 27WON exhaust stands as the definitive upgrade for your Honda Civic Si and Acura Integra.
Available in configurations ranging from a front-pipe back system, incorporating a 2.5″ front-pipe, to a comprehensive turbo back exhaust system, finding your ideal balance of sound and performance is assured.
Dual Exit Design: Harmonious Sound and Appearance for your Civic Si
The dual exit variant of the 27WON exhaust system is engineered with two precisely positioned resonators on each side of the vehicle. This strategic placement not only maintains a visually clean aesthetic but also orchestrates a deep, resonant sound profile for your 2022 Civic Si. This sophisticated two-phase system employs both an expansion chamber resonator and an absorption resonator. This combination effectively mitigates a broad spectrum of frequencies, both high and low, while ensuring unimpeded exhaust flow. This optimized flow reduces back-pressure, thereby unlocking enhanced performance potential for your Civic Si. For those opting for the single exit version, a singular resonator is utilized on the passenger side, resulting in a slightly more aggressive overall sound.
Single or Dual Exit: Tailor Your 2022 Civic Si’s Style
The dual exit versions of this exhaust system feature dual 100mm polished tips, adorned with our signature logo plates, enhancing the premium aesthetic of your Civic Si or Integra. For a bolder statement, the single exit system utilizes a single 115mm or 4.5” tip. Constructed from the same high-grade stainless steel as the exhaust system itself, these tips are meticulously designed to perfectly complement the bumper cutout, providing a seamless and integrated appearance on your Honda Civic Si 2022.
Enhanced Exhaust Flow for Peak 2022 Civic Si Performance
Optimizing exhaust flow is paramount to maximizing engine performance. To achieve this, 27WON has increased the exhaust piping diameter from the factory 50mm to a more substantial 63.5mm. This enlargement significantly reduces back pressure, facilitating a more efficient expulsion of hot exhaust gases from your turbocharger. This upgrade results in a 58% increase in cross-sectional area, providing ample support for future power enhancements and contributing a deeper, more resonant exhaust note to your Civic Si 2022.
Customize Your Sound: Multiple Configurations for Your Civic Si
The 27WON exhaust system for the 11th generation Honda Civic Si and 5th generation Acura Integra is available in 3 distinct configurations, allowing you to precisely tailor the sound output of your vehicle. Choose between a front-pipe back system only, featuring a 2.5″ high-flow front pipe, or a complete turbo-back exhaust system, which includes our 80mm high-flow catted downpipe. This modular design allows you to build your system incrementally or opt for the full system for maximum performance gains and a unified sound profile for your 2022 Civic Si.
- Optional: For those selecting the Single Exit version, Honda OEM Part # 71591-T20-A00 is available to seamlessly fill the driver side bumper trim opening, ensuring a factory-like finish.
Single Exit Option: A Tuner Aesthetic for the 2022 Civic Si
New for this model year is the single exit variant of our FE1 exhaust, catering to enthusiasts who favor a tuner-inspired aesthetic. If making a bold statement at your next car meet is a priority, this option delivers unparalleled visual impact for your Civic Si 2022. This version mirrors the dual exit in construction and performance but channels exhaust flow through a single path to the passenger side, utilizing one resonator. A slightly enlarged stainless-steel tip completes this configuration, amplifying its visual presence and solidifying its tuner-centric appeal.
Premium Stainless Steel Construction for Lasting Performance
All 27WON exhaust systems are manufactured using T304 stainless steel tubing. Utilizing CNC mandrel bending and precision TIG welding techniques, each system is built for durability and optimal performance on your Honda Civic Si 2022. Finished with a brushed treatment, the exhaust system maintains its pristine appearance for years to come, ensuring it looks as impressive as it performs.
Superior Seal with Tri-Bolt Flange Design
Rejecting the compromises of slip joints and leak-prone 2-bolt flanges, 27WON employs 3-bolt flanges for their exhaust systems. This design ensures optimal sealing and precise alignment during installation, providing a robust and reliable connection for your 2022 Civic Si exhaust system. Each system is complete with custom-matched gaskets, guaranteeing a leak-free, enduring performance upgrade for your vehicle.
Precision Fitment for the 2022 Civic Si
Beyond power and sound, visual appeal is paramount. 27WON has meticulously engineered optimal hanger locations and flange orientations to guarantee a flawless fit. Slotted bolt holes and extended hanger rods provide adjustability, allowing for fine-tuning the system’s positioning beneath your car, achieving the perfect stance and aesthetic for your Honda Civic Si 2022.
