By pursuing a full system replacement we can eliminate the restrictive cat assemblies, the particulate filters, and the giant 7 ⅝ connection point to the factory rear muffler assembly. A simple flange optimization to our previous generation GT3 Competition Headers allows us to get rid of the factory 991 gen connection point requiring costly OEM clamps and donut gaskets and utilize a more efficient v-band connection point.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/soulpp.com\/wp-content\/uploads\/2026\/02\/Soul-Performance-Products-GT3-Competition-Headers-RD-Collage-2.jpg\" target=\"_blank\" rel=\"noopener\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eREAR EXHAUST SECTION\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/soulpp.com\/wp-content\/uploads\/2026\/02\/Soul-Performance-Products-Porsche-992-GT3-Factory-Muffler-Flow-Paths.jpg\" target=\"_blank\" rel=\"noopener\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eWith limited room under the vehicle we had to craft an intricate solution and loop the exhaust to keep the cats in line after the headers to maximize exhaust velocity. A muffler proved to be the most effective way to reduce the drone level under 3k rpm enough to meet our goals for reduced cabin presence for an exciting touring level of sound. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eWith valves open, exhaust is free to flow through 3” piping and an x-pipe that merges the exhaust flow for a higher pitched, smooth sound with maximum flow characteristics. With valves closed the exhaust is routed through secondary flow path piping and a bespoke SOUL muffler. The internal design has little to no restriction in the flow path, using straight-through perforated piping to allow exhaust gasses to escape and become muffled in the surrounding packing material of the muffler body. The muffler also incorporates an internal x-pipe to allow the exhaust flow to merge smoothly. All of these characteristics are crucial towards reducing and smoothing out the drone in the sub 3,000rpm range while enhancing the higher pitched note we were after in both the valves closed and open conditions.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe catted\/catless sections are interchangeable. You can reduce the chance of CELs with 200cell cats and tone down the exhaust if need be, or you can run the catless section to amp up the fun and performance on track. We also utilize a tip plate (same style as used on 991 GT3’s) allowing one to switch between tip assemblies\/styles.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/soulpp.com\/wp-content\/uploads\/2026\/02\/Soul-Performance-Products-Porsche-992-GT3-Valved-Exhaust-Muffler-Drawing.jpg\" target=\"_blank\" rel=\"noopener\"\u003e\u003c\/a\u003e\u003cspan\u003e.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eVALVE CONTROL\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cspan\u003eThe exhaust valves on this car have electronic actuators mounted to a free moving mechanical valve body.

The actuators themselves are what keep the tension on the valve bodies, so you can’t take them off and have the valves default open via spring pressure like previous vacuum actuated OEM valves.
