Exhaust pipes that feed into rear muffler are rusting out. Previous owner welded (vs. clamped) rear muffler to center muffler pipes. Therefore, I've been told I must replace center AND rear muffler.
Is this sound advice? (excuse the pun...)
Any way to salvage center muffler? DIY job for a novice?
Ideas?
Thanks to all.
