Unfortunately, the hard part is helping people understand that a U.S. made unit, the cost of the high grade stainless steel would cost far more than 400 dollars alone, and this does not reflect the manufacturing costs or any other costs associated with the unit.

There are many members on this forum that can attest to having the cheaper quality x-pipes and what has happened to them after some decent amount of use.
The question is do we really need the high grade stainless steel to make a good working exhaust? There is no doubt that the high grade stainless steel will cost considerably more than 400 in marterial..Then we are back to the question, do we really need that for the car or is it just another reason for people to justify their insanely amount of spending on an exhaust? As far as I knew, exhaust can be made from highest grade aircraft alumium or carbon fiber which will cost even more than 5k..Again do we really need it on the street? the answer is no.. we need a simple exhaust that doesn't rust or break apart after a reasonable amount of street and track use...if you are seriously consider putting the car into real races, then by all mean go for the best out there..otherwise there is no point..
