Porsche 991.2 Carrera (with PSE) Sport Catalytic Converters

I have had my Soul PP sport cats installed for a few months now and I have waited on purpose before posting a review. I have many miles in many different conditions and think I can fairly give a good review now of them. As others, I watched a ton of videos online and read forum posts as I had no opportunity to hear the sport cats in person. That concerned me a lot, but I will try to give a few comments to put your mind at ease in you are on the fence on these. My absolute #1 comment is that the videos online simply do not do justice at all to the sound. Not one of them. It is not even close. When I first started up my car inside my garage with the sport cats on, I was shocked at the level of noise. They are loud. I do not feel they are obnoxious, it is just that after listening to a million videos they simply do not capture the live feel obviously. Many people have wondered if they are enough, as I did since the videos sometimes made them out to be more, but perhaps not much more. That was my biggest concern when I contacted them prior to purchase. What if I install and I do not notice much difference? I can tell you that this will 110% not be the case. You WILL notice them. They very much alter the noise level. Soul and others here told me subjectively 25% more, since I am a numbers guy, I might go as far as saying it is more like 40% more. Windows down, sunroof open, windows closed, does not matter what combo..you notice the difference..in a good way. I have since had the opportunity to drive a 991.2 base with PSE without Soul PP sport cats, and I was reminded why I wanted them in the first place. Without them, I personally notice very little difference inside the cabin. Prior to buying my car, I test drove it and went for an extended drive constantly turning the PSE on and off. From inside the cabin, with the windows closed, I could tell little difference. This was my first instance driving a 991.2 with PSE and I was shocked. I thought to myself, but it has a sport exhaust now, why can I not hear it??? This was my biggest gripe on the car..it looks like an iconic sports car, drives like one, but sounds so muted. To me without the sound in the mix, the package falls apart. I can tell you honestly that with the Soul SC the package is completed. Perfectly. Start this car up now outside, or inside with someone around and it announces itself to the world. At WOT it just simply makes this car even more addictive. The cats IMO make the burbles less robotic sounding, and deepen the exhaust note to a more exotic tone..more throaty..more robust. Just driving around town the noise is intoxicating, you simply do not want to stop. But wait, your wife says she hates loud exhausts? Your neighbors called bylaw enforcement? Turning off PSE brings the car back to awfully close to stock before the cats install, and the car sounds like an Accord. The best of both worlds if need be. Brilliant on Porsche and Soul PP for not ruining that apsect. Finally with windows up you can hear the exhaust, you know what you are driving is special. I so much hated that missing before, the sport cats transform this car to what it should have been out of the factory. Windows down? Oh my. Bring a change of shorts. Seriously, it just implants a permanent grin on your face..I dare you to try to not get goosebumps. Again, it just finishes off the package absolutely spot on and IMHO is worth every single penny Soul PP charges. Simply brilliant. PS A special thank you to John at Soul PP. I am a MASSIVE stickler for good customer service and John nails it out of the park. Always available, always helpful, incredible insights on everything. John was a huge reason I went with Soul PP because he took care of me from day one.
