wel im wondering how do u brace your wastegate? people say that tubular turbo manifolds tends to crack around the wastegate part, gets me worried about my manifold cracking on that part! lmk

Don't buy a piece of junk ebay manifold and you'll have zero problems.

I should mention, if you DID buy a piece of junk ebay manifold, you should not use a solid brace to the manifold on the wastegate flange - use something that allows for movement of the wastegate as the metal expands without it binding. Putting a solid brace will cause it to tear elsewhere.

Its not the wastegate that causes the cracking .

well its not a ebay manifold
it's a custom 304 ss sch 10 manifold

if its a think good quality manifold you will have no problem. The cheap *** ebay ones for $99's are the ones that need braced/ replaced.

im gonna be pushing about 15-18psi the most, do u guys recomend bracing the wastegate flange?

if it is a decently made manifold, good welds, proper penetration and back purged, you should not have any issues.

4 years on a full race ramhorn, wastegate is still there.

Dump tubes will also play a very big part in a manifold cracking there, the excess material hanging off, and vibrating really take a toll .
