Muffler guy says crack in manifold could mean replacing converter and manifold too?
Yea, there welded together.
Yes both need to be done at the same time
shop around for prices
Why don't you take it down (or maybe not necessary) and weld it to a good shop?
Manifold cracks are VERY difficult to weld. Replace the parts.
