We had the pleasure of upgrading Matt’s beautiful 991.1 Carrera GTS with several modifications. While the GTS is certainly an outstanding performance vehicle off the showroom floor – there’s always room for improvement and refinement!
Our aim with the Valved Exhaust System was to refine the level of daily driving comfort without sacrificing the race inspired tone and straight-through exhaust design. A larger resonator would not yield the results we are looking for while requiring some revisions for clearances – this could compromise the high flow design principles of our exhaust. Adding higher flowing aftermarket headers – like our Long Tube Street Headers – to an aggressive rear system without proper sound attenuating features could result in a overly loud, possibly unpleasant driving experience. Nearly 40% of our customers paired their rear exhaust with upgraded headers making it imperative that we consider such a configuration and engineer the exhaust appropriately. Helmholtz resonators (also known as anti-drone tubes) are an effective way to reduce undesirable frequencies when engineered and utilized correctly.  The 991.1 Carrera has an inherent 3,000-3,500 RPM range where drone can present itself when you add higher flowing exhaust components. Our goal was to filter out the undesirable frequencies in that range while smoothing the valves closed to open transition on factory PSE equipped cars. Our Long Tube Street Headers increase volume to an enjoyable level while adding more response and power to turn your Porsche into a true drivers car!
We also installed an aFe POWER Black Series Cold Air Intake System. Not only does it look incredible, but it adds extra tone in the cabin as well.
