ok, after reading more than 2 1/2 pages of this, I have something to say... I really am not going to get into the whole "Flowmasters will turn your 10 second car into a 15 second car" VS "Flowmasters are the ultimate performance muffler/exhaust/ect" agrument, mainly because I do not have a lot of first hand knowledge on it. There have even been some comments that people did not care if they lost some (or a lot) of thier performance, but they really liked the sound... Did it ever occur to anyone that Flowmaster might be fully aware that they are a little more restrictive systems (I am not saying they are or are not, I really don't feel like getting in the middle of this), but they made a choice to keep it that way to keep thier sound on it? I mean some guys can tell when a car rolls by that it has a Flowmaster on it. I know a few guys that would never go with anything but a Flowmaster because they just love that sound so much. There is a perfectly good chance that Flowmaster made that descision because in the end, unless you are going for a straight race car, most people are not going to care too much about the + or - hp they are going to lose as long as it is not MAJOR.
In the end what I am saying, is there is a good chance that Flowmaster is just going for a certain segment of the market, both in price and what they desire out of the car. Remeber, demand drives the market, and businesses try and figure out what thier customers want.
