I put a Corsa Catback on my wife's new 2023 GMC Yukon AT4

‪@CORNYOTE‬installs a Corsa Performance Catback on my wife's new 2023 GMC Yukon AT4.

The little 5.3 LS goes from a quite and docile single 2.25 exhaust to a quad tip 3" monster!

Corsa is known for managing drone and this exhaust has none at all. It's the perfect combination. Quite cruising, but lets you know it's alive when the skinny pedal goes down! The wife was initially a hard sell, but she absolutely loves it now!! WIN/WIN!!

We replaced the rear lower bumper with one from a Denali, then add the Corsa Quad tips for an amazing look and sound!! Parts used are listed below:
