[QUOTE="1Kona_Venom, post: 16623949, member: 101429"] If a scientific study were conducted, I think the highest ranked popular exhaust combo would easily be 1. Headers 2. O/R H Pipe 3. Stock mufflers To Toms point here, yes the 13-14 OTA pipes on GT's do have a factory resonator. I was awake staring at the ceiling fan last night; Ford specs with these resonators were probably adhered to withstand stockish power levels of a GT, not a Shelby GT500. Makes you wonder why they didn't install them OEM on Shelbys? Sort of the comparison between catalytic converters. Brand X makes a Hi flow H Pipe, but than Brand X also makes another Hi Flow H pipe that is considered "green". The reason for the differences in not only price and functionality is the internal metal composition. A "green" mid pipe will hold up under hotter conditions. At this point, I'm looking to swap out OTA pipes simply for the fact mentioned earlier. If nothing else, I'll know first hand how much, if any, those factory resonators aided in sound [/QUOTE]
