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.
