Exhaust-original 2 cat and muffler. The flange gasket after the last cat had 1 of 2 broken bolts. To repair without an oxy/act torch, use a grinder and cut the bolts. Buy a new gasket and a 2 hole or 3 holes Nickson Split Flange. Need 2 and get a Grade 8 set of smaller bolts to help in assembly.
Grinder and cut both bolts. Smooth down.
