2005 Ford Mustang Exhaust Systems

I bought this as the sounds on videos sound the best. I have done many self install exhaust systems and this by far was the worst fitment ever. I didn't have the time to install it and took this to an awesome shop I use. They were like sure 2 hr tops. Calls me tonight and said this was noway fitting with the way it was made he had to cut hangers on pipes reweld them add to the over axel pipes to get a proper fit. They even felt bad and said we are only charging you for the 2 hrs. So I really hope it sounds good when I pick it up tomorrow. I seen a few videos online with fitment issues but didn't think it would be this bad.
