WHY should you have to anyway TTI did the correct thing and refunded my money long ago they do make a great product and I would buy from them again but not this header
You shouldn't have to. But I was suggesting it for anyone else who might have the same problem but were looking for solution to use the headers they had. Some people don't mind bending and denting their headers... others would rather get the right header. You did the right thing by returning the headers. The company also did the right thing.
