Frequently Asked Questions
What is the CORSA 14859?The CORSA 14859 is a 3.0-inch Sport cat-back exhaust for the 2015-2020 Chevrolet Tahoe and GMC Yukon 5.3L V8, delivering a bolder and more commanding exhaust note through twin polished 4.0-inch tips using RSC technology to eliminate highway drone.
How does the 14859 differ from the 14859BLK?Both are the same Sport cat-back with identical fitment and sound. The 14859 uses polished stainless tips; the 14859BLK uses matte black PVD tips for a darker appearance.
Is the 14859 drone-free?Yes. CORSA RSC technology is tuned specifically for the 5.3L V8 Tahoe and Yukon to eliminate drone at all driving conditions.
Does the 14859 fit the Tahoe Z71?The Z71 is a package, not a distinct trim. Confirm your base trim (LS, LT, Premier, etc.) is in the fitment table. Most Z71-equipped Tahoes will fit.
Does this fit the Yukon XL or Suburban?No. The CORSA 14859 is designed for the standard-wheelbase Tahoe and Yukon. The longer Suburban, Yukon XL, and Escalade ESV use different part numbers.
Does installation require cutting or welding?No. The CORSA 14859 is a direct bolt-on cat-back at factory mounting points.
Is a tune required?No. The 14859 retains factory catalytic converters and does not alter engine management.
