The 24 shops on this page handle mufflers, pipes and catalytic converters in and around Portland, ME. What each one says about welding, custom work and warranties comes from its own website; ratings and quotes come from public reviews.
Usually a heat shield that has rusted loose, or a broken rubber hanger letting the pipe knock against the floor. Both are quick and cheap on a lift. Left alone, a swinging pipe tears at the joints and turns a small job into a section replacement.
Not completely, but you can make your car the harder target. Shields and cages bolt over the converter, etching the plate number on it helps police trace it, and parking where the underside is hard to reach or well lit puts thieves off. High-riding vehicles get hit most because nobody needs a jack.
It depends on the fitter. A universal box welded in by someone who knows the car can sound and last as well as the factory part for less money. Fitted badly it hangs wrong, drones, or cracks at the weld. Ask what warranty covers the part and the weld.
