Oh I agree with you on a lot of that Sal... he's got the money so I really don't care how he treats that WK, it's his and its his to beat up if he wants. I just find it funny how crappy of a job he did CONSIDERING he has so much expendable money. That looks like something i'd expect from a highschool kid. He [seemingly] has enough money, why not sketch it up and bring it to an exhaust shop that specializes in diesel trucks? He could have that all done in 5-6" exhaust pipe and used some heat wrap in the locations in the engine compartment to prevent heat soak. Instead, he's bragging about an atrocity that's akin of the potato gun i made in 10th grade....
And yea, they couldn't find a better way to bring it into the cab? Maybe all the comments on youtube will help him put a bit more effort in "rev 2"
