Stock exhaust manifold with mods?
 

My exhaust manifold is cracked and I've already welded it back together 3 times. I don't have the cash for a 3 piece so how long will a stock replacement manifold last with my mods? If the mods even matter.

New or used stock manifold? The more heat cycles they have, so going from fairly hot, to cool, back to hot, etc, etc..the more prone to cracking. It's hard to say if you purchase a used one how long it would last. But a new stock manifold should last you awhile, even with your mods, IMO.

Price of a new manifold from Dodge would probably cost more than a three piece. Around here, it would.

^^ that is probably true. For now he might be better off just grabbing a pretty decent used one from a wrecker or something and run that for awhile.

it was a new one but I lost out on eBay I should have just bought it a quit trying to save some pennies LOL.
