Evo3 Exhaust Y pipe leaks
 

.

Can you weld?

Edit: I guess I should ask if it is the gasket or a joint on the pipe?

Definitely a new gasket if you haven't tried that yet, or you could try using 2 gaskets at once. I've never tried that, but I hear it works.

If it's leaking at the welded "Y" joint, I suggest you take it to a muffler shop and they can weld it for you.

If it's leaking at the flange, either get a new gasket (or as suggested above, use two gaskets) or "make" a gasket out of thicker material.

Its at the flange, do you know where can i get a new gasket or a thicker gasket for it?

your local autoparts store or amazon or another online retailer.

OK, it's leaking at the flange.

I have to ask, when you tighten the nuts on the flange, are you tightening each side alternately, till they are tight ..... ??

When the two sides of the flange are butted up against each other, in a relaxed fashion, do they meet squarely .. ?? If not, try to "bend" the longer side till the two sides meet flush and the flange is secured.

You're sure the "flange onto the pipe" weld is good ... ??

Like @RobertPaulson suggested, you could take the gasket into the auto parts store and ask them for a new one. OR maybe buy some exhaust gasket material and make your own.

If it's a small leak, some exhaust sealer goop may stop it up.
