ok ive been wondering this for awhile. l have looked at plenty of body kits for my mustangand have found really cool ones but was too afriad to buy them cause then l wanna put an exhaust system on it but they have diffrent ones that come out the side and the back etc.. for instance the ones out the back the body kits that have the cutouts for the exhausts in the back will it basically fit all exhausts that go out the back? Same with the side ones like if it has one pipe cut out and l have a two pipe exhaust what would l have to do or would l have to find one that is for two pipes? thanks!

First get the new exhaust and install it on your mustang. Then find a body kit that will fit on the exhaust that you have, if you cant find one that is perfect you can always just slightly change the body kit yourself.
