Hey everyone,
I recently installed the Corsa Sport 2.75" Cat-Back Exhaust (Part No. 21209) on my 2025 Bronco Badlands 2.7L, 4-Door with HOSS 3.0. The sound is absolutely amazing — deep, aggressive, and no drone. However, I’ve noticed some issues and wanted to see if anyone else with HOSS 3.0 has experienced this:
Issues I’m Feeling:
  • Noticeable vibration at higher RPMs during acceleration.
  • General vibration compared to stock.
  • Feels like the engine is working a bit harder than before (though this might just be perception).
Background:
  • Exhaust is original Corsa.
  • I bought it used from the first owner .
Questions:
  1. Any other HOSS 3.0 owners running Corsa Sport — do you notice more vibration at higher RPMs?
  2. Could this be an installation/fitment issue (hangers, clamps, heat shield clearance) unique to the HOSS 3.0 setup?
  3. Any real effect on drivability/engine load, or is this just how the sound/feel changes with Corsa?
  4. Bonus: Has anyone clarified if installing this cat-back impacts the Ford warranty?
Would love to hear from other Badlands or HOSS 3.0 owners who’ve gone with the Corsa system.
Thanks!
