Its not bad as long as they are not leaking. Unfortunately polybutylene pipes have the best chance to start leaking at some point and it can be costly to repair.
As I understand it polybutylene hasn't been removed from the formal plumbing code, however the sale of polybutylene was quickly phased out in or around 1995 which is when the major class action lawsuit (Cox v Shell Oil) was settled for just shy of a billion dollars. As you likely know there have been countless problems with all variations of polybutylene pipes and associated fittings, and although it's still listed in the code, consumers should not consider this an endorsement of quality or performance.
the velocity of the metals and the engine is going to be in his bad behavior.
It cleans the water, mainly of sediment and metal particulates which are bad for your pipes.
Galvinized piping fell out of favor because they a-didnt last as long as the new copper pipes and b-there was concern about the zinc coating contaminating water. If there in good condition for 70 years your probably fine. If your concerned have your water tested for lead and zinc.
no they are not

Polybutylene pipes can be identified by their gray color and flexible, plastic-like material. They were commonly used in plumbing systems in the 1970s to 1990s. If you suspect you have polybutylene pipes, you can hire a professional plumber to inspect your plumbing system for confirmation.
Polybutylene pipe is a discontinued pipe.
When looking to renovate a home, it may be natural to look for ways to cut back on costs. For example, when installing a new plumbing system, many may want to save money by installing polybutylene pipes. However, this form of piping should be avoided. The affordable polybutylene pipes have undergone an extreme amount of scrutiny over the past 30 years, and they not violate almost every building code in the United States, Europe, and Canada. The pipes were the center of many different class-action lawsuits as the plaintiffs have shown that the pipes can be deteriorated by small traces of chlorine.
The most effective methods for repairing polybutylene pipes include using push-fit fittings, crimp fittings, or PEX pipe replacement. It is important to consult with a professional plumber to determine the best solution for your specific situation.

Polyethylene and polybutylene are two common types of flexible tubing used in plumbing, and both are used in hot and cold water supplies in place of traditional copper lines.
If you run the engine without pipes , you will inevitably start a fire under the hood from the flames shooting out of the exhaust ports
Polybutylene is typically made through polymerization of butene or butadiene monomers. These monomers are chemically bonded together in a repeating pattern to form a long chain polymer called polybutylene. The process usually involves high pressures and temperatures, along with catalysts to control the reaction.
The price of a polybutylene pipe will depend on how big it is, if it has any alloys in it, and how long it is. Without this information, it is near impossible to give a quote on price.
Probably not, but where does the water from the sink and shower go and what sewer problems are you having?
