Alright I have a 40 series flowmaster muffler and wanted to replace my stock muffler on a 2000 v6 stang. what are the bolt sizes, and/or how hard is it to remove the whole back half of the exhaust so I can cut the stock one out. Has anyone else done this? what are the bolt sizes, and how would i get it off? I have done some exhaust work on my 94 cougar, but it came out like ****, so i really want to do this as clean as possible, so i would really like to take it off the car.
