When you start up the car have a buddy help you plug the right exhaust tip with his hand while you plug the left one, if you get a pressure build up and it kinda wants to shoot both of your guys hands off, then you should be good, but if you are both plugging and you aren't getting a building of exhaust gas pressure, then you have a leak! This is the test I use and one time I did in fact have a leak.
