Next 408 exhaust question - tips

[Sam410]

I was always under the impression the downturned tips were to prevent black spots on the back wall of your garage.

When I got my 410 it came with lovely chromed brass tips, but sadly one got pulled off leaving a very steep driveway and the then squashed by a following car. Since then I have had a number of cheap Halfords downturned chrome tips, which were always dreadful quality and only lasted a year or two before rusting and looking terrible. However a couple of years ago I found some on eBay (https://www.ebay.co.uk/itm/322995767559) which I am very happy with - stainless steel, decent thickness, and still in good condition nearly 15,000 miles later.
