Description

Take Your Civic Si from Mild to Mean with the Right Exhaust Tone
The Civic Si cat back exhaust by Invidia delivers what every 10th gen Si driver really wants: more sound, more soul, and zero drone. This premium Q300 system is engineered specifically for the 2022+ Honda Civic Si (1.5T), offering a deep, clean tone and improved throttle response without being obnoxious. Whether you're tearing up canyon roads or just commuting to work, this is the mod that keeps giving.

You’re getting more than a sound upgrade—you're unlocking performance with 70mm mandrel-bent piping that reduces backpressure and boosts exhaust velocity. Rolled stainless steel tips give the rear end a bold, polished look that makes your Si stand out in the crowd. Everything fits like OEM, with bolt-on installation, no cutting, and perfect alignment straight out of the box.

Engineered with 304 stainless steel and robotic TIG welds, this system is built to last in any weather. And the best part? It keeps your cabin chill—zero drone at cruising speeds, so you won’t lose your sanity on highway drives. The Civic Si cat back exhaust balances style, sound, and street manners in a way most systems just can’t.

  • 70mm Mandrel-Bent Piping – Maximizes exhaust flow and reduces restriction for better throttle response

REVIEWS

This exhaust completely changed the feel of my Si. Super clean sound—no annoying drone. Fit like a glove, took me and my buddy 90 minutes max to install. Highly recommend for anyone who daily drives but still wants that sporty edge.

Couldn’t be happier. The tone is perfect—not too raspy, just clean and deep. My neighbors haven’t complained once, and I love the polished tips. Worth every penny if you want a balance between style and function.
