Exhaust elbows

[Al]

Greetings,
In reading various post where cost of exhaust elbows are indicated as being expensive the question on my mind is that because it is thought so compared to what?
I am somewhat perplexed with the specifics of exhaust elbows as the two boats of any size and powered by diesel, have had and have home made elbows constructed with stainless steel pipe fittings. The cooling water fittings are brazed or welded in to these elbows.
Not had any problems and they appear to be lasting for years as they have not been replaced with OE or after market elbows.
There is no significant cost involved. What am I missing here given the need to replace this piece on any boat where cost is a factor or availability for that matter.
curious minds want to know
Regards,
Al

Not expensive imo, for the L120, except for the shipping to get them here. They are heavy!

The issue can be the cost of factory replacement parts.
Our 1980 vintage Cat 3406 is on it's 3rd exhaust elbow that I know of. 4 years ago the factory cast part was quoted at $7,000. I had a stainless fabricator make one for $900.

DEPENDS , if the exhaust elbow is hooked to the engine with pipe fittings , they are common and hardly "that" expensive.

Over $100 but not by much.

If its a special item that only fits a certain engine other suppliers may offer it .
