Is it where the pipe connects to the muffler? If so put in a gasket and problem solved

I had a problem with my Magna Flow catback and I had a problem with my exhuast leaking after the resonator pipe, also check where the downpipe meets the resonator pipe. Are you using spring bolt kit or nut and bolt.
