Top Speed Test Pipes a few years later

[ultimate1]

One of my secondary cats caused a CEL and time to replace one of them. I like what I have read about deleting the secondary cats which I am learning serves no purpose.

I am considering buying the Top Speed test pipes and have PMed a few members but no response yet either due to the long weekend or other factors. Anyway, I am curious to know who has been running them on a 2.7 base boxster with stock muffler and how has their experience been with the product? Some have said that they were happy shortly after they installed the test pipes but I would like to see comments from those who have had them on their boxster for a year or longer.

Thanks in advance
