Overview

This Milltek Sport cat-back exhaust fits the 2014-2016 Porsche 911 GT3 and GT3 RS (991.1) with the 3.8 or 4.0 liter flat-six. These Milltek parts replace the heavy rear silencer on the 991.1 GT3, adding volume and saving weight; choose a valved bypass with factory tips or a full rear silencer delete with Milltek tips. Each system is built for this exact chassis, so it follows the factory routing, hangs from the stock mounts and keeps the ground clearance of the original exhaust. Compared with the factory steel parts it is lighter, flows more freely and gives the engine a clearer, stronger voice under load, without the harsh highway drone of a cheap straight pipe. Every 911 GT3 991.1 system is made from T304L stainless steel with mandrel-bent tubing, so the pipe keeps its full size through each bend and resists corrosion for years. It bolts on with the factory hangers and clamps, with no cutting or welding needed. It swaps the factory exhaust from the catalytic converters back, using T304L stainless steel pipework, and bolts to the factory mounting points.

How to Choose

Start with the System. Valved Rear Silencer Bypass valves that keep the factory quiet and loud modes. Rear Silencer Delete is the Milltek system listed for this car.

Then pick an Exhaust Tip Finish: Factory Tips (reuses the factory tailpipe trims), Polished (bright polished stainless), Cerakote Black (a black Cerakote ceramic coating), Brushed Titanium (a brushed titanium finish). The finish changes the look only, not the sound.

Features

  • T304L stainless steel construction
  • Mandrel-bent and made to bolt to the factory mounting points
  • Valved versions keep the factory valve function

Fitment Notes

  • Fits the 2014-2016 US-market 911 GT3 and the 2016 GT3 RS (991.1). The valved bypass also fits the 991.2 GT3, which has its own page.
  • Both remove the rear silencer, so they are noticeably louder than stock.
