However, please note that 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.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eDEVELOPMENT AND TESTING: \u003c\/b\u003ePorsche’s development and introduction of the 718 GT4 RS signaled the brand’s commitment to extracting the greatest potential out of the mid-engined sports car’s platform. But due to a variety of necessary constraints, there was still something left on the table. Our exhaust solutions aimed to deliver unrivaled sound character from the GT3-derived engine in addition to squeezing out the extra performance available by optimizing each component of the exhaust system. In testing, we could feel the results but couldn’t quantify them—until now.\u003c\/p\u003e\n\u003cp\u003eIn an exclusive collaboration, M-Engineering offered us their dyno facility in Pompano Beach, Florida, to test virtually every exhaust configuration we offer for the GT4 RS. Working with local supercar YouTuber Mickey Hernandez (Miami Miles), we were finally able to realize the performance potential that was available, and give customers a neutral viewpoint of what there really is to gain from an exhaust upgrade—whether just a single piece or an entire system.\u003c\/p\u003e\n\u003cp\u003e\u003c\/p\u003e\n\u003cp\u003eOur goal when developing the GT4 RS exhaust suite was to maximize tubing diameter to accommodate the increased exhaust flow from the 4.0-liter flat-six. That proved itself in practice when put on the dyno where even our most promising ambitions were realized once the data was returned to us. Every component from our portfolio delivered us positive results, extracting meaningful power in accessible driving conditions. Combining products with our popular packages multiplied those gains by offering generous midrange power and torque and maintaining that throughout the full rev range.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/soulpp.com\/wp-content\/uploads\/2026\/02\/Stock-vs.-Competition-Headers-Sport-Cat-OAPs-Valved-Exhaust-System-vs.-Competition-Headers-OAPs-Valved-Exhaust-System-1-scaled.png\" target=\"_blank\" rel=\"noopener\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eWhether your ultimate goal is sound volume, quality, or additional performance, these tests have validated that the SOUL Performance exhaust suite is capable of ticking every box on the list.\u003c\/p\u003e\n\u003cp\u003eFor drivers looking to maximize the capabilities of sound and performance, our Performance Packages extract everything possible from an exhaust upgrade to elevate the experience to a level worthy of the RS moniker. Unrestricted Competition Headers mate to a choice of free-flowing Over Axle Pipes and our Valved Exhaust System, capitalizing on the most sound and performance potential but crucially retaining civility for street use.\u003c\/p\u003e\n\u003cp\u003eThe result is a comprehensive solution that generates sound and power gains all the way to redline. Accessible midrange torque and power, the biggest dip in the stock system’s dyno graph, is straightened out to realize a linear increase that maintains an effective delta in the totality of the rev range, even when fitted with our high-flow catted option.\u003c\/p\u003e\n\u003cp\u003eEach component owns a distinct role in achieving these results, beginning with the headers. The factory headers on the GT4 RS cram a lot, including the primary cats, into a small space that sacrifices tubing length and diameter and is a roadblock to power right at the start. Our Competition Headers make no compromise, eschewing those cat cores and using longer tubing and an expanded merge collector to meet the 3-inch flow path of the Over Axle Pipes. The OAPs, in either Competition or Sport configuration, replace dense cat cores and particulate filters and the uncorked exhaust flow delivers an immediate response with aggressive sound and tangible power gains.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/soulpp.com\/wp-content\/uploads\/2026\/02\/SOUL-Performance-Products-718-GT4-RS-Headers-Production.jpg\" target=\"_blank\" rel=\"noopener\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/soulpp.com\/wp-content\/uploads\/2026\/02\/SOUL-Performance-Products-718-GT4-RS-Resonated-Over-Axle-Pipes-Build.jpg\" target=\"_blank\" rel=\"noopener\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eReplacing the rear muffler would be the final step to maintaining a full 3-inch flow path as it utilizes full oval tubing to meet that objective while still fitting in the space provided. But it’s also primarily responsible for producing the motorsports character and tone that is famous of Porsche GT cars. Blending the exhaust flow through an x-pipe elicits a smoother high-pitched tone than the factory PSE system with valves open or closed. But the latter condition utilizes the muffler and is assisted by the secondary flow path’s Helmholtz characteristics to provide an effective elimination of exterior volume and interior presence.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/soulpp.com\/wp-content\/uploads\/2026\/02\/SOUL-Performance-Products-718-GT4-RS-Valved-Exhaust-Build.jpg\" target=\"_blank\" rel=\"noopener\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eFor those who truly want it all—the sound, the power, and a measure of cruising comfort—our Performance Packages fulfill every driver’s wish list.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\u003ch3\u003eAvailability \u0026amp; estimated lead time\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSpecial-order notice:\u003c\/strong\u003e Most SOUL Performance Products components are built or finished to order.

But for those who’d like to dial it back when appropriate, a Valved Exhaust System would meet their sound goals with valves open AND valves closed. With a full 3-inch X-Pipe in either valve operating condition, that wonderful high-pitched flat-six sound comes to life but can be suppressed when necessary. Combined with Resonated Over Axle Pipes, that sound can be further amplified along with a boost in performance by uncorking that factory bottleneck. It is a complete package for those who truly want it all. Unfortunately, there was more that it came with: drone.\u003c\/p\u003e\n\u003cp\u003eTo drivers who opt for the civility of a Valved Exhaust System, excess drone is not an acceptable byproduct. The GT4 RS’ potent 4.0-liter flat-six brings plenty of it, especially once we’ve turned up the volume on it. Instead of just accepting defeat, we went after a solution, even as it required several evolutions and plenty of testing. Our design of “drone canisters” was finalized and installed as it successfully hit the volume requirements we calculated to target the drone frequencies in the low-to-mid 2,000 RPM range, shifting the drone zone down the rev range and reducing peak frequencies significantly. As a result, drivers can enjoy the motorsports tone that our X-Pipe creates in its fullest expression, or mute it when necessary and cruise comfortably.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/soulpp.com\/wp-content\/uploads\/2026\/02\/SOUL-Performance-Products-718-GT4-RS-Valved-Exhaust-Installed.jpg\" target=\"_blank\" rel=\"noopener\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eDue to the design of the system with these drone canisters, fitment is only possible when combined with aftermarket Over Axle Pipes. Our Street Package pairs our Valved Exhaust System with our Over Axle Pipes for a remarkable change in character and volume with valves open, but drone reduced as much as possible with valves closed for as civilized a cruising experience as we could develop—especially driven in Sport mode where the optimal shift points during typical driving are outside the peak “drone zone.” This package allows the OAPs to be optioned as Competition or Resonated, with the Competition selection offering more overall sound level potential with valves open, closer to the Race Exhaust Package.

It has little to no restriction in the flow path, using straight through piping that is perforated to allow exhaust gasses to escape and become muffled in the surrounding packing material of the muffler body. We incorporated a second internal X-pipe to allow the exhaust flow to merge smoothly. These characteristics combined were crucial towards reducing and smoothing out the drone in the 1,800-3,000rpm range while enhancing that higher pitched note we were after in both the valves closed and open conditions.\u003c\/p\u003e\n\u003cp\u003eHelmholtz resonators further reduce drone for a more refined cabin experience for a bold tone with minimal drone.\u003c\/p\u003e\n\u003cp\u003e\u003c\/p\u003e\u003ch2\u003e\u003cb\u003eHAND-CRAFTED CONSTRUCTION\u003c\/b\u003e\u003c\/h2\u003e\n\u003cp\u003eMandrel bent, durable .065″” T304L stainless steel tubing\u003c\/p\u003e\n\u003cp\u003eBack purged TIG welding (with \u003ca href=\"https:\/\/soulpp.com\/2019\/12\/13\/tech-talk-airgas-arcal-prime\/\" target=\"_blank\" rel=\"noopener\"\u003eARCAL™ Prime argon gas\u003c\/a\u003e) ensures proper weld penetration for exceptional strength and longevity\u003c\/p\u003e\n\u003cp\u003eWater jet cut brackets are made to ISO 9001:2015 standards with ultra-tight tolerances of +\/- 0.003 inches for extreme precision\u003c\/p\u003e\n\u003cp\u003eFabricated using thick-gauge aluminum fixtures that act as a heat sink during the welding process to prevent any warpage\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eEXHAUST TIP SELECTION\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eFor those looking to maintain the factory appearance, this system can be used with OEM exhaust tips.
