PV muffler, how long

Hello , Just wondering if anyone that bought the pv 1 had any problems with leaks, i bought mine 3 years ago and was told today that i have a black spot in the front where it is starting to leak. Does anyone else have this problem and does anyone know how long they should last or if there is a warrantee on them?

If it's a hole on the body of the muffler it should be an easy fix. Since they're pretty thick-gauge stainless either the hole can be welded or patched if larger.
