Sigh, question asked a thousand times….
In all seriousness, depends on your tolerance for how aggressive you can get with the dealer should they choose to void warranty for a part that has zero affect on wear. With that said, if you want to be uber conservative, then an exhaust would be the only option.

Mods don’t void the warranty. Mods that can be blamed for causing an issue normally covered by warranty, can void the warranty.

I’ve had my motor replaced with an aftermarket inlet and charge pipe, and exhaust. They couldn’t prove any of those mods caused or contributed to the issue. Full motor replacement under warranty. Hell, they put the inlet and charge pipe back onto the new motor for me.

Long story short, mod away. Just be aware of what you’re modifying. There’s no instant void. I would look into a catted down pipe and exhaust if it’s fun noises you’re after.

^^^ agreed with the above. Just be aware OP that not all dealers will be willing to so easily replace parts under warranty. Some will fight you to the bitter end to ensure you do not receive support via warranty. Hence why I mentioned, you may need to become nasty to fight for your warranty.

There is a thread with the same question at least a few times a week.

Nothing voids your warranty.

But if your upgrade damaged another component, the dealer will not replace it for free. They will still do all the other non-related repairs and services under warranty.

Exhausts, intakes, coolers, charge pipes, and inlets are all safe since they don't add extra pressure to the car.

Tunes and turbos are the only gray area upgrades, so it's important to get a proven and reliable tune and use their recommended maps. This way you are sure you won't break anything, and you don't have to worry about the warranty
