SOUL Porsche 718 GT4 RS / Spyder RS Race Exhaust Package

DEVELOPMENT

Borrowing its 4.0-liter flat-six from the 992 GT3 Cup, the 718 GT4 RS came delivered with serious motorsports pedigree. In order to satisfy worldwide regulations and meet production deadlines, certain components of the platform left performance and sound on the table. That’s what we’ve aimed to maximize.

Our Race Exhaust Package tackles the biggest bottlenecks we found in the factory exhaust system, those being the over axle pipes and the rear muffler. The over axle pipes house a redundant cat core along with a particulate filter that is empty on North American cars, allowing for an immediate transformation upon replacement of that component in particular. Our Competition Over Axle Pipes employ oval tubing for a full 3″ diameter and eliminate those corks in the flow to deliver the greatest flow into the rear muffler.

The GT4 RS’ rear muffler is carried over from the standard GT4, restricting the flowpath to the same diameter of the GT4 despite the increased engine output. Our Race Exhaust System utilizes a single flowpath that maintains a 3” diameter all the way through the tips. Our Resonated version with anti-drone tubes helps to reduce unwanted frequencies, while our Non-Resonated version is the ultimate lightweight solution for maximum sound from the GT4 RS.

EXHAUST TIP SELECTION

For those looking to maintain the factory appearance, this system can be used with OEM exhaust tips. However, the OEM tips feature a much smaller diameter inlet, requiring the system to be necked down, which introduces a restriction and reduces overall performance. To extract the most from your GT4 RS, we strongly recommend selecting our high-performance exhaust tips, designed to complement the full 3-inch system without any compromises. Choose between double wall tips or our Weissach style stainless steel tips.
