[QUOTE="Robert M, post: 15025003, member: 9628"] I have often wondered............If Ford/SVT, through their extensive testing, felt a need to change the exhaust system from 2.50" to 2.75" at the 550hp level, what about earlier cars (2007-2010) that have been upgraded well beyond 550hp, and are still blowing through the smaller 2.50" system? I also believe that the upsize in exhaust contributed to an amount of hp gain in these 2011-up cars, not sure what the number is, but Ford did not spend the $$$ to upgrade the exhaust size for no reason. When I installed a full 3" on my 2008 GT500, it responded like a completely different car from the oem 2.50" cat forward with only a 2.50"catback Borla added at Shelby, especially the way it now pulls through the rpm range..... I think the muffler hanger configuration also changed on the Mustang/GT500 somewhere in this time period, like two hang points on the earlier cars and three points on the later cars? <<Or something like that?
