You can hear the exhaust break around 1min 25secs, and thats when things start to get scary..
the culprit: exhaust failed, ruptered high pressure p/s lineand p/s fluid ignited. We used a 22" long stainless DP, followed by the long aluminum exhuast. We used header wrap at the front of the exh, to protect the p/s hoses from heat, and this likely shortened the exhaust's life.. This aluminum exh has seen a lot of abuse, many hours of dynoing, street driving and practice sessions. The heavy loads during the time attack event were just too much and it gave up
fortunately it was an easy cleanup, the car is already back to blingin! needs a little work this weekend, but will be 100% by monday.
