Sometimes the alignment makes it hard for the special mid-muffler o-rings (D shaped) to do their job. I always use some hi-temp Silicone sealer on the header pipe before sliding it in and then wipe away the excess, leaving a neat radius of it to seal the pipe/mid-muffler junction and let it cure overnight. When using Silicone sealer, always make sure the surfaces are clean.
