If you're looking to give your Audi S3 a voice that matches its spirit, the APR Catback Exhaust System is where it’s at. Seriously, this isn't just any exhaust; it's crafted from T304 stainless steel, which means it’s built to last and resist corrosion. You can see the quality in the details—like the TIG welding that’s argon-back-purged, giving it that clean, professional finish. It’s not just about looks, though; this setup is designed for performance.

The straight-through mufflers? They deliver a deep, throaty growl that turns heads without choking your engine. And that Helmholtz resonator? It works wonders to cut out the annoying drone that can ruin your drive. Plus, the cast 3” to quad 2.5” rear splitter is a game changer. It provides a smooth transition for exhaust gases, ensuring your ride breathes easy while looking sharp from behind.

Installation is a breeze, thanks to the strong, high-quality brackets and OEM-style clamps. You won’t need to be a mechanic to get this thing on your S3. It’s designed to fit like a glove with both the stock and APR Race DP exhaust systems, so you can swap it out without any hassle. And if you’re into the motorsport look, the removable 4” polished slash-cut tips add that extra flair to the rear end of your ride.

Oh, and if you want to save a few bucks, you can opt to ditch the rear mufflers and valves. Just keep in mind that this will change the sound and flow a bit, but it’s a solid option if you’re looking for something more stripped down.
