Exhaust question

Allow me to ask a dumb question. What is the difference between the mufflers/silencers I can buy from Flying Spares and those that I can pick up at a corner auto parts store? Besides price and the “coveted” RR logo, I mean.

5935 will need new exhaust which intend on doing along with new mounts and motor mounts.

I reckon you won't find pipes & silencers to fit at your local auto parts store but I could be wrong. Next time I need a new exhaust I plan on having a bespoke stainless steel one made at a local exhaust centre copying the shape and design of the old one.

You won't find anything to fit at a local auto supply store.

Some of the exhausts are stainless, mostly found on the 2-door cars. Which ones do you have? (stainless is non magnetic on those cars - and yes - magnetic stainless exists, but not on our exhausts.)

I have been told by a Rolls specialist in NJ before that the factory exhaust has a specific back pressure tuning that is critical to the engine and to help prevent it from burning exhaust valves. Now whether this is true or not I have yet to test, but it does pose an interesting theory.

The exhaust on my 1980 SWII California is totally stainless, pipes and silencers.

Thank you? I think........

I had heard that they needed RR specific mufflers/silencers. That’s why I’m asking. If I have to pay RR prices for them that’s not an issue. If I don’t, we’ll, I’m going that route. It’s a project car but I also am well aware that it’s a “high end” car as well. So what’s the difference? What makes them special?
