Description

The first and only valved exhaust built for the 11th gen Civic Si. Frontpipe-back, dual exit, 304 stainless, with a remote-controlled valve and both resonated and non-resonated midpipes in the box. Valve closed, it's quiet enough for a 6am start. Valve open, it isn't.

Fitment

Confirmed: 2022–2026 Honda Civic Si (FE1). A car goes on that list after it's been on the lift, not before.

Fits both factory and aftermarket frontpipes, so a stock car and a built one bolt up the same way.

Non-Si 1.5T or Integra? Not confirmed yet. We think the Hibiki fits more cars than the ones we've proven, but we aren't going to sell you a $1,300 exhaust on a hunch. The 2022–2025 Civic 1.5T non-Si sedan trims, the 2023–2026 Integra 1.5T, and the Civic sedan/hatchback trims are all suspected, not confirmed.

One thing you can check yourself right now: look under the back of the car. The Hibiki needs rear exhaust hangers on both sides, driver and passenger. Not every 1.5T car has both. If yours only has one, this system won't mount no matter what the badge says.

Got both hangers and willing to let us test fit? Get in touch with the year, trim, and photos. Somebody putting a car on a lift is the only way the list gets longer.

What it does

Until now the choice was the one everybody knows. Go loud and accept that a four-hour drive turns into a headache somewhere around 2,400 rpm, or stay quiet and wonder why you bought an Si. That isn't a compromise so much as picking which half of the car you stop enjoying.

The Hibiki runs a remote-controlled valve. Closed, the volume drops and the highway drone goes with it, and it will tame an aftermarket catted or catless downpipe. Open, the car breathes. One button from the driver's seat. No app, no menus, no waiting for a phone to pair.

Four exhausts, one purchase

Most valved systems make you pick resonated or non-resonated when you order, and then you live with it. We ship both. Two midpipes and two valve positions means four sound profiles from the same system, and the quietest and the loudest are a long way apart.

Setup What you get
Resonated, closed Quiet enough for a 6am start and a four-hour highway run
Non-resonated, closed Still civil, with more of the car coming through underneath
Resonated, open Loud on demand without committing to it full time
Non-resonated, open The loudest, rawest version of this platform

The first and last are the two exhausts most people are choosing between when they shop. Here they're the same part, and the difference is a midpipe swap and a button. Change your mind in six months and the other pipe is already on your shelf.

Install

The controller wires in with a fuse tap and tucks up behind the trim. No cheap 12V plug hanging off the dash, nothing to route around your knees. Once it's in, the only sign it's there is the fob in your pocket.

That's also the fiddliest part of the job. Bolting the exhaust up is straightforward. Getting the wiring into the cabin and doing it neatly is what takes the time, and it's worth doing properly.

It's a frontpipe-back system, so you're working under the length of the car and you'll want it up in the air. Doable on jack stands if you're patient, a lot easier on a lift.

Developed on our own car

This isn't an off-the-shelf design with a new sticker on the box. The Hibiki was developed and tested on the TSP FE1, our shop car, over real miles. Every bend, hanger and flange was checked on the actual platform, which is also why the confirmed fitment list is short.

Before you buy

Will it drone?

Closed, no. That's the entire point of the valve. Open, it's an exhaust, so it's loud. But still no drone.

Do I need a tune?

No. It's a frontpipe-back system, so it doesn't touch anything the ECU is watching.

Will it work with my aftermarket frontpipe?

Yes. It's designed to bolt up to both factory and aftermarket frontpipes, so it fits a stock car and a built one the same way.

What about the hatch, a non-Si 1.5T, or an Integra?

Not confirmed yet, and we won't sell you one until it is. They're all on the list to test. Check whether you have rear hangers on both sides first, then get in touch if you want to help us confirm it. That's how the list gets longer.

How hard is this install?

Middle of the road. The exhaust itself is bolt-on, but you're working under the length of the car and you'll want it up in the air.

The part that takes the longest is the valve controller, since the fuse-tap wiring means running it into the cabin and doing it cleanly rather than just plugging something in.

What does the warranty cover?

One year from the date of purchase, plus support if anything comes up during install or use. If something goes wrong inside that window, message us with your order number and a photo and we'll take it from there.
