As I said, the pipe diameter is pretty big compare it to being any other stock pipes.. However, some good axle back exhaust will sound nice. The HP difference between 177 and 190 is mostly due to the redline limitation. Perhaps, you could be right.
You don't want HP gain from an exhaust and an intake... they never give you a good number back.
