To the experts (EXPERTS!!!):

Doesn't it stand to reason that if you have a set of pipes (no matter the brand, let's just keep them constant in this example), and you have 20-25% HP loss on average (expert opined), wouldn't you get a higher percentage of HP LOSS on a 800 HP engine vs a 400 HP engine? Remember, the headers and pipes are the same for both engines in this case. It would seem to me that the same headers/pipes would do more choking on a higher powered car.

Or is the difference negligible?
