Porsche 991.2 Carrera (with PSE) Trackback Turbo Back Exhaust

I’ve got a 2019 911 Carerra T configured nearly as lightweight as they could be ordered from the factory. My modification philosophy has been to remove weight rather than add power as, frankly, less weight is more fun than more power on the street. I’ve added an Antigravity battery, Essex/AP Racing brakes, and headers to reduce weight further. Exhaust after the turbos was my next planned mod, mostly as I wanted to take weight out of the tail of the car before track season. The Soul Trackback exhaust is the lightest setup I could find as it deletes the entire muffler. I wanted to retain catalytic converters, so I got the setup as seen above. By “as seen above,” I mean the exact hardware in that picture is current hanging under my car! Soul says the catless version drops 27lbs over stock, and I bet this one drops ~22lbs or so. I don’t daily the car and really only use it for weekend fun and track days, so I’m willing to compromise and accept some drone. Removing the stock exhaust isn’t hard, but the stock cats and muffler are heavy and cumbersome. A second pair of hands or a jack help a lot. Also, I suggest removing the rear fender liners to get easy access to some tough-to-reach heat shield bolts. Install is a piece of cake. I did use new gaskets though Soul said the stock ones can be reused. I used the stock flanged nut on the stock turbo stud but used the Soul-provided bolts, nuts, and washers on the other 6 holes. The bracket that holds the stock muffler is used to holds the L-shaped pipes, and I did bend both sides of the bracket slightly so that the L-shape part coupled with the cat part without having to push parts into place. How’s it sound? ROWDY. For some reason it’s louder Normal and Sport than in Sport . I typically use rev-matching on the track, and I don’t like the synthetic burbles, so I’ll likely keep the car in Sport most of the time. I have no CELs so it seems the cats are doing their job. The test conditions are terrible as we’ve got howling winds today and I’m using an iPhone in the cupholder . At top speed, I’ve got wind buffeting at an airspeed of about 130mph-140mph which completely drowns out the exhaust, but you can really hear it rip in 1st and 2nd: It absolutely SINGS at 7000rpm. There are definitely more awesome turbo sounds at lower RPM as well. Does it drone? A little bit, as expected, but really only around 2000 /- a few hundred RPM. At 65mph I heard as much road noise as wind noise as exhaust noise. There was no drone in 7th gear at 65mph, but wonder if I’ll hear it at a more-realistic 75-85mph. More testing to come. I’m very happy with this setup and look forward to tracking the hell out of it this season.
