TSP Hibiki Series Valved Exhaust System | 22+ Civic Si FE1

Fits:

• 2022-2026 Honda Civic Si (FE1)

The FE1 Civic Si has been out for years without a single valved exhaust actually built for it — TSP built the Hibiki to fix that. Closed, the valve keeps things quiet and drone-free for early mornings, long highway stretches, and rolling through the neighborhood without turning heads. Open it up and the Si gets the deep tone and burbles it should've had from the factory, with no screech or embarrassing rasp at wide-open throttle. A remote-controlled valve switches between the two on demand, wired in clean through a fuse tap rather than a cigarette-lighter module hanging off your dash.

Every system ships with both a resonated and non-resonated midpipe, so you pick the character that fits your build — a more refined everyday tone, or the loudest, rawest note the platform can make — and you can swap between them whenever you want. It's a complete frontpipe-back system in 304 stainless with 3" mandrel-bent, TIG-welded piping and a dual-exit layout, developed and validated on TSP's own FE1 shop car, and it picks up cleanly from either the factory or an aftermarket frontpipe.
