Wisconsin Snake -
"I have a set of side pipes that are restrictive and was told to update them with less restrictive version which would free up ~50 hp...
After reading this thread, maybe I will pass or at least use them until I feel like I need more HP and can handle the car."
You will like the less restrictive pipes - I got mine right before CRII went down
and they do make a difference in the right direction.
