Do you plan to offer a version compatible with the 2019 STI exhaust? I love your products but don’t really want to buy a whole catback system right now. Thanks!
The flange location and flange is different on the axle back unfortauntely. You can order the mid pipe conversion kit below to make it fit or you can order a complete catback and replace the whole catback.

Will it fit a 2019 sti?
Our axleback system does not fit the 2019 STI. However, our catback system fits with no issues. https://www.extremeturbosystems.com/collections/15-19-sti-exhaust-systems/products/ets-subaru-sti-2015-catback-exhaust-system
