Invidia R400 Catback exhaust with Triple titanium burnt tips for the Civic Si Sedan. Attaches to front pipe, super easy to install if you have some jack stands and a driveway, easier if you have a lift! Had on the car less than a week, it’s still on the car actually until I get an appointment to uninstall it next week.

Has a deep/bass-y sound to it in the low range, and opens up nicely when WOT. Purrs like a kitten when it’s idling with a nice grumble to it. However it’s Not exactly what I’m looking for in terms of sound, so I’m going back to stock for now. Not obnoxious, drone is pretty much non-existent after driving it for a few hundred km.

Asking $1,000 CAD firm. Due to weight and because I threw the packaging out, I’d like to keep it local pick up or can meet if you’re within a couple hours of London, Ontario.

Not that I’m expecting this but in case someone was interested I’d be open to trading for a different catback possibly, like MAP Street, AWE Touring for the sedan (can add cash possibly). But otherwise not looking to trade for anything else at this time.

Anyways, PM if interested and I can give my number to text for serious buyers. Attached one picture of the exhaust installed, not a good one but can get more if needed.
