Milltek Rear Silencers for Porsche 911 992.1 GT3 (2021 onwards) – Revised Sound, Rear Section Only
This is Milltek's rear silencer for the Porsche 911 992.1 GT3. It's a standalone replacement for the rear silencer only, swapping it for a version tuned for a different sound without changing anything further forward in the system. It's offered in 4 tailpipe finishes, so you can pick the setup that suits how the car's used.
It's for owners looking to fine-tune the exhaust note at the tailpipe end, typically alongside an existing cat-back or axle-back system, rather than a complete exhaust upgrade on its own.

You can choose from: GT-100 Brushed Titanium, GT-100 Burnt Titanium, GT-100 Cerakote Black, GT-100 Polished. The finish is cosmetic and does not change the sound.
Is it road legal?
Milltek does not list EC approval for this part. Any exhaust used on the road must still meet noise and emissions rules, so check the requirements where you live.
Do I need a remap?
No. It fits behind the factory catalytic converter, so no software changes are needed.
