Fits:

• 2022+ Honda Civic Sedan 1.5T (EX, Touring)

Choose Non-Resonated if you're keeping the stock downpipe (front-pipe-back or cat-back). Choose Resonated if you're running a downpipe upgrade with a full turbo-back system — the extra resonator keeps NVH comfortable when paired with a downpipe. Non-Si trims don't get a resonated option for cat-back/front-pipe-back (too quiet to be worth it), and turbo-back isn't offered non-resonated (too much NVH with a downpipe). Reach out before ordering if you're unsure which fits your plans.

_______

The stock exhaust on EX and Touring Civic Sedans is notably quiet compared to the Si, so 27WON built a system specifically tuned for the non-Si 1.5T CVT platform — available as front-pipe-back, cat-back, or full turbo-back.

Twin Helmholtz resonators out back are tuned for a crisp, deep tone while minimizing drone — exhaust gas gets pulled into these side air chambers and pushed back out, creating a distinct throaty note not found on other systems for this platform. Piping increases from the stock ~50mm to 63.5mm (2.5"), reducing back pressure and supporting future bolt-on power gains. The system uses your stock rear bumper with no shroud replacement needed, and installs with stout 3-bolt flanges instead of leak-prone slip joints or 2-bolt connections.
