there is a rev hard manifold i want to buy, but it has a hairline crack in it. he said it does not leak and he can weld the crack. he is including a downpipe with it, should i pick it up for 200 bucks or not? let me know what you all think

 

if it dont leak it will.

 

got any pics by any chance?

 

it can make a big differnce i had a few hairlinecracks and i replaced my mani and got the 2psi i was missing when from 6 to 8 then when i did the soapy water test i found a leak in my bov gained full spool with 500 less rpm now fullyspooled 8psi at 2800 rpm
