Mine has a leak in it. What will it cost, and how hard to install (not that I plan on doing it). Its a 1989 2.8L. Thanks.

 

If its a gasket that's leaking it's real easy on your car.If its the manifold you can get the leak welded.There should be alot of them at your local junkyard if you need a new one.

 

Thanks, he implied that it was the metal. He said "Its a bitch, probably around $300". I am trying to see if its worth it. Assuming it is really screwed up and I had money to burn, would a performance exhaust manifold make a difference?

 

so 300 is the estimate for a new manifold and install.That seems with in limits.well on that 2.8 I don't think a performance manifold will make a difference to justify the extra money spent.

 

Always upgrade, never replace! Get some headers if you're going to go to $300 worth of trouble. Install them yourself and then have a shop attach the y-pipe to your stock cat. You'll spend maybe $50-100 more than you were planning for the stock parts, get better performance (that the little 2.8 sorely needs) and you can resell the headers to some other 2.8L owner later on when you decide to swap in a V8.
