Just installed the Borla S-Type Cat-Back Exhaust Systems for 2019-2024 1500 - 140860 and here’s my experience:
Without resonator: Loud, aggressive, and full of drone. Outside the drone RPM range, the sound was deep, sporty, and really fun.
With resonator: Drone is gone, but much of the aggressive tone I liked is softened. Still sounds good when you get on it, just less in-your-face.
The system comes with two mufflers: a front resonator and a rear/mid muffler. I skipped the resonator at first since I didn’t want to cut the mid-pipe—turns out that little piece is key to keeping drone under control (Borla knew what they were doing, I didn’t).
Pros: Solid build, easy bolt-on, aggressive sound without resonator
Cons: Drone without it, tamer with resonator, price
Well, I guess I can check exhaust off my Mod list, next up leveling kit, then wheels/tires.
