Title: Cosmetic options for these clamps.
Post by: McCabe-Thiele (Ted) on September 23, 2023, 02:00:41 PM: I know there have been discussions to the effect that re-chroming does not last on exhuast pipe clamps - never mind the cost.
I am undecided when it comes to the replacement exhuast - the Delkevic comes with SS I think so I would not need to restore them.
The original four pipe system is not completely out of the equation as yet.

Is there a coating finish that can stand the heat that works without running into treble figure costs?

No matter what coating you apply the rough finish means that unless the coating is unusually thick the rough spots will break the surface of the coating, that allows water access and that means rust, in a relatively short time they’ll look as bad as they were before you started.

I’m experimenting with grinding the rough surface off and then either chroming or ceramic coating them in a chrome like finish. However, it’s time consuming and boring to prep the clamps.

However that’s almost free to do and the ceramic finish isn’t very expensive, about £5-10 per clamp.

Delkevic is far cheaper but it’s nowhere near as attractive as the 4 into 4 system, you pays yer money and takes yer choice.

Today I like the old original four pipe system.

For now I might just settle for some paint so they do not rust in storage!

my clamps looked similar condition to yours, I cleaned them up and used a small touch up brush to paint between the fins only.

I used aerosol Dupli Color Supertherm 800c silver paint, it cured when the engine heated up and still looks OK now about 5 years later.

Of course it's not concours finish, you'll need to buy new clamps for that...

All the best

I wonder if there are an aluminium set off a different model that would fit the 550?
