I had the HKS with and without test pipe and I didn't really notice a loss or a gain in hp, but the sound was amazing. Don't expect a huge hp gain with any dual exhaust for our S.

 

Are you getting the Hi-Power exhaust or the Hyper exhaust.. THe Hi-Power exhaust is the newer one and it's full stainless steel from cat to muffler. The older one isn't.
