Braided Flex Pipe
#2
Visually you can look with a flashlight and mirror from above for tearing of the braided mesh covering and signs of carbon deposits. You can have a helper or lovely assistant operate the throttle at different rpm ranges and listen for a whooshing sound or buzzing.
If it's on a lift a technician can feel for a leak with gloved hands, preferably welders gloves or heat resistant work gloves, that exhaust is screaming hot at the flex joint...around 800 degrees.
