I just got home from work, I will check their info in the morning. If their info doesn't state a size, I will give them a call. I will also get the dyno graphs up for you guys.
The full system also comes with a 'Air Filter Power Kit' already figured in with its price. I don't know if I can get a sound clip of video though, but I will see what I can do. I noticed that they are still using the O2 sensor, so no power commander should be needed.
