Y2K_MustangVert said:It depends on what you are going for. If you want a nice sounding system go with the 'Flows, but if you want a system that is really loud and scares little children get the 'Packs. I had the Packs and the Pro-Chamber installed at the same time about a year ago and I still, to this day, haven't heard a better sounding exhaust anywhere. The only complaint that I have heard come from people that get the Flows are that they wanted it to be louder.
drexebo said:do the packs have at least the horsepower gain given by the flows or more? because, according to magnaflow's website, the magnaflows outperformed the SLP catback as well as either borla or bassani. I know the packs aren't exactly like the SLP "resonators," but they are a little closer in design than the flows.
