What happens here

With the exhaust installed, the next crucial step is to test the engine and listen to the new exhaust note. The presenter starts the GMC Yukon XL to hear how it sounds with the custom downpipe. The initial startup reveals a surprisingly quiet, almost 'normal' sound, which is an unexpected but welcome outcome given the modifications. This test confirms the functionality of the exhaust system.

Goal: Verify engine starts and assess the new exhaust sound.
