LOL i am doing my MBA in finance and marketing. Trust me brand name and popularity of a product has alot to do with the price of an item. Anyways I dont know the quality of the product... maybe i am being ignorant and assuming that all steel and aluminum are the same and mandrel bent means mandrel bent which is why i am asking poeple who have this product to tell me if its truly a junk or is it worth the 400 dollar price tag? If money was no object then i would have bought a $500,000 ferrari instead of a $5000 Z. Dont get me wrong, I love my Z and want to get the best products for it but if something like monza will get me 15hp vs 16 or so produced by the more expensive systems and lasts me 3 years like the warranty says i would be happy.
