Rs2 Mani cracks

[audinut]

Hi can anyone tell me if the cracks inside this RS2 mani are going to cause me issues in the future ?

The outer cracks I can get welded very easily but the inner cracks are slightly more difficult due to space restrictions

anyone have experience of doing something like this?

Is that a real OE RS2 exhaust manifold or a clone? Real ones have a high nickel content in the casting alloy.

If you are going to weld it you need to get it
nice and hot and use inconel wire with a tig, assuming
its a real one it should be fine.

yes its real - should i try and get the inside welded ?

I did get my RS2 original manifold welded but it last perhaps 5000 kms.
The cracks were very similar to the ones in your picture.
Welding was done by professionals: http://www.sintesicompetition.com/site/
but still it cracked again nicely and presto.

Wagner it's the (expensive) solution IMHO, expensive (not that much in comparison to the original from Audi) but better flow better fitting and very good quality.
