i want to know the real gain too... cuz i had Invidia mid-pipe + HKS Hi Power, Invidia mid-pipe + Greddy SP Elite, ARK DT-S mid-pipe + Greddy SP Elite and Complete ARK DT-S cat back... it feels that whatever paired with Invidia mid-pipe is better.. but then again w/o dyno results i can't prove anything.. lol...

Up to 11 whp doesn't sound too bad. Conditions and supporting mods will effect that number such as intake, engine condition ( a new car will dyno higher than one that needs a tune up), and geographical conditions such as humidity and altitude, and what dyno is being used. So on a dry cooler day with an intake and a newer vehicle, yes you would probably get about 10-11. On average, probably around 8whp.

Manufacturers are going to show numbers at optimal conditions with supporting mods (some tuned) with a car in good condition. They aren't lying by those numbers but real world is going to be a different story.
