I watched the show that they did work on a yellow C7 corvette. What a joke of a show. They spent 60 seconds showing how they changed headers. Then nothing but advertisements. Then they installed a stabilizer. That took all of ten seconds with them just showing one of them tightening the last clamp. Then back to more advertising during the show. Then on to the commercials.
Then they show the results from the dyno shop with the corvette. 683 HP from a car that normally has 455HP from just headers. What BS. If that car made 683 HP it had much more work done to it before the headers were installed.
The show is a waste of airtime.
