I tried to keep this thread from being a bash-fest but it appears that even those who have not even used the product are jumping on this guy.
We don't know if this is a product failure, or if it is a tuning issue, or if it is just the wrong application.
I feel bad for the three customers that have had their issues with this product. But for those of us that have been actually using the product and have not had any issues, how can the product be "proven" to be JUNK?
I checked mine last night and my three pieces (two spacers and a heat shield) looked brand new after five months of driving.

Sometimes, it is much easier to blame someone then it is to apply effort to solve the actual problem.
