311 exhaust
 

I found my exhaust manifolds leaking water. What suggestions does anyone have for replacement of stock exhaust for reasonable price. I have 420s with trs drives.

The 420's have a pretty nice exhaust system. Where is it leaking? Maybe it just needs the faces cleaned and new gaskets.

They are leaking below elbows. I took them apart to replace the gaskets,but found that two manifolds are roted away no gasket surface left. So i need to replace them. Used set or new.

Eddie Marine EMI Thunders are probably your best bang for the buck. Stainless Marine makes decent stuff too, might be more $$

Shop around for deals on them.

Bummer. Hiowever, a weld build-up and remachine may still be more cost effective than new. If you have a good machine shop you trust, it may be worth checking into. Loss of base metal at the gasket surfaces does not mean the manifolds are non-useable, repairs can be done.

Thanks for all the info I'll check into that also.

Gil dry headers!
