With valves closed, the exhaust is routed through smaller piping and a bespoke SOUL muffler we designed to fit with the X-Pipe in the confined space above the rear diffuser and meet our sound goals. This muffler was crafted to match our high standard of drone fighting mufflers like the rest of our existing Boxster \/ Cayman line that we have become known for. \u003c\/span\u003e\u003c\/p\u003e \u003cp\u003e\u003cspan style=\"font-weight: 400;\"\u003eInternally this muffler is quite unique. 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\/span\u003e\u003c\/p\u003e \u003cp\u003e\u003cimg decoding=\"async\" class=\"aligncenter size-large wp-image-11678\" src=\"https:\/\/soulpp.com\/wp-content\/uploads\/2020\/10\/Soul-Performance-Products-Porsche-718-Valved-Exhaust-Muffler-Drawing-1024x508.jpg\" alt=\"\" width=\"1024\" height=\"508\" srcset=\"https:\/\/soulpp.com\/wp-content\/uploads\/2020\/10\/Soul-Performance-Products-Porsche-718-Valved-Exhaust-Muffler-Drawing-1024x508.jpg 1024w, https:\/\/soulpp.com\/wp-content\/uploads\/2020\/10\/Soul-Performance-Products-Porsche-718-Valved-Exhaust-Muffler-Drawing-510x253.jpg 510w, https:\/\/soulpp.com\/wp-content\/uploads\/2020\/10\/Soul-Performance-Products-Porsche-718-Valved-Exhaust-Muffler-Drawing-64x32.jpg 64w, https:\/\/soulpp.com\/wp-content\/uploads\/2020\/10\/Soul-Performance-Products-Porsche-718-Valved-Exhaust-Muffler-Drawing-300x149.jpg 300w, https:\/\/soulpp.com\/wp-content\/uploads\/2020\/10\/Soul-Performance-Products-Porsche-718-Valved-Exhaust-Muffler-Drawing-768x381.jpg 768w, https:\/\/soulpp.com\/wp-content\/uploads\/2020\/10\/Soul-Performance-Products-Porsche-718-Valved-Exhaust-Muffler-Drawing.jpg 1280w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"\u003e\u003c\/p\u003e \u003ch4 style=\"text-align: center;\"\u003e\u003cstrong\u003eDRIVING IMPRESSIONS\u003c\/strong\u003e\u003c\/h4\u003e \u003cp\u003e\u003cspan style=\"font-weight: 400;\"\u003eWe found that the particulate filters in the over axle pipes put a big damper on the overall sound level and how it carries into the cabin. Think of it like a cork in the middle of the exhaust, letting a PSE muffler replacement tease you but not giving you the full experience. Combining our \u003ca href=\"https:\/\/soulpp.com\/product\/porsche-718-gt4-cayman-valved-exhaust-system\/\"\u003eValved Exhaust System\u003c\/a\u003e with our \u003ca href=\"https:\/\/soulpp.com\/product\/porsche-718-gt4-cayman-competition-over-axle-pipes\/\"\u003eCompetition Over Axle Pipes\u003c\/a\u003e is when the skies open up, the sun shines down and the Porsche Gods have blessed us with the sound we’ve all been waiting for. Inside and outside the car, windows up and down, the experience is nothing short of transformational. At wide open throttle it sounds like a weapons grade symphony. Very reminiscent of a GT3 at 9k, and arguably better than any stock GT3 you’ll ever hear on the street. Ditching the factory over axle pipes finally allows the car to have some burble on deceleration but nothing too over the top, just enough and just right. When you do a hard shift, a visceral crack erupts to really put a smile on your face. Not like a shotgun blast going off, more like a reward for actually driving the car how it’s meant to be driven. When you’re off throttle cruising around, it’s relatively docile and comfortable (that secondary flow path at work). If you want to fly under the radar and significantly cut down on sound level outside the car, you simply close the valves and away you go in stealth mode. However, even with valves closed the tone and character of the exhaust is still there, not dead muted like the PSE muffler. It has cabin presence, some ever so mild drone\/resonance in low rpms that we consider quite reasonable compared to the other configurations we’ve tested – even with valves open it’s quite reasonable. We’d almost say it’s more a character of the system and it’d be a shame if there wasn’t any to tease you into squeezing on the gas to hear more of it.
