Overview

This Milltek Sport valved rear silencer is made for the 992.1 Porsche 911 GT3, sold in the US for the 2022 to 2024 model years. It takes the place of the factory rear silencer, the last box in the exhaust before the tailpipes, and keeps the factory exhaust valves working, so the car's sport exhaust button still switches between its quieter and louder settings.

Owners of a naturally aspirated 4.0 liter GT3 usually want more of the engine's sound without losing the car's factory behavior. Because this part only replaces the rear silencer, the rest of the factory exhaust stays in place, and the change is focused on tone and volume at the back of the car.

Milltek Sport has built performance exhausts in England for more than 40 years. The silencer is made from T304L stainless steel, uses 70 mm (2.76 in) pipework, and is designed to fit the factory mounting points with no cutting.

How to Choose

There is one choice on this page: the exhaust tip finish. Factory Tailpipes is the lowest-cost version (SSXPO171). It is the rear silencer alone and re-uses the tailpipes already on your car. The four GT-100 versions add Milltek's 100 mm round tips and a Cerakote black trim mounting plate. Polished is bright stainless, Cerakote Black is a black ceramic coating, Brushed Titanium has a satin titanium look, and Burnt Titanium has the blue and gold heat-tinted finish. The silencer itself is the same in every version.
