A lot of people have a lightweight flywheel, I do not currently but I am sure others can chime in on good/bad.

I am not saying you are incorrect but only repeating what I have seen thus far. Typically there is a difference of 6 hp as compared to the Stillen. If I were to guess the average HP is about 12 wHP. Ironically I think peak HP may not be what I should be looking at anyway. I may decide on the exhaust based on torque and weight of the total system.

Remember though, dyno numbers can be made to look however they want for a company. Not saying anything about any company, but I would focus on weight, quality, overall curve of power.

Agreed...I am thinking about the Ark exhaust but not sure what the weight of the system is and truth be told I am less concerned with the weight of the ehaust itself (since its in the back of the car) and more concerned with the header weight. Balance is my goal not overall weight savings.
