Fair enough, as you say it will reduce mid range and low end slightly but my entire point was that with the size diameter the same as stock i really don't think that it would effect the engine so dramatically..

Yeah, pug didn't cobble it together but they had to keep to certain requirements to keep it legal, doesn't necessarily mean it can't be improved.. so, according to what you're saying everyone should be running a stock exhaust for best power unless we're running over 250hp.. in the real world, i highly doubt it makes that much difference..some stock '6s have been dyno'd at anywhere from 155-173hp.. on that same dyno was another 2 6's both with 'performance exhausts' one RR'd at 163hp and the other at 173hp... I think other factors would cause much more of a difference than exhaust..
