UNLEASH the hidden soundtrack on your GPF/OPF/PPF equipped Porsche 991.2 GT3 RS with the Brooke Race Exhaust manifolds & RSS stage 2 ECU software.
The 991.2 GT3 RS is Porsche's latest track day tool and with that comes the latest emission regulations which mute the exhaust tone and limit the volume. You'll probably already know just how much better the pre-GPF GT3 RS' sound vs. the post-GPF cars do.
Don't know what a GPF is? It's a 'Gasoline Particulate Filter', and can also be called an OPF 'Otto Particulate Filter' or even a PPF for 'Petrol Particulate Filter'. All of these acronyms mean the same thing and are a filter placed in the exhaust to catch particulates which are periodically burned off depending on the conditions and more often than not completely block over time and require replacing, they are a filter after all.
With the boring GPF/OPF/PPF talk out of the way, let's get into the interesting stuff. The Brooke Race Exhaust Inconel system is a complete system featuring Inconel headers with high-flow cats which mate up to either the factory centre muffle or in this case, a BRE Inconel centre muffler with larger exhaust tips.
With the GPF/OPF/PPF removed a check engine light for emissions will illuminate, to prevent this, the RSSStage 2 ECU remap is installed and at the same time the fuelling, ignition, variocam and many other maps inside the ECU are optimised for improved power and torque output.
