Has any one out there with a v6 had any issue with the factory header cracking and can any one suggest some aftermarket replacements I have a 2001 mustang v6

 

You don't have a factory headder, it's an exhaust manifold. The passanger side exhaust manifold is known to crack becaust the a/c drips onto it, a common problem. There are a couple of different brands you can chose from, either shorty(stock length) or long tube headders. Check out some of the site sponsors on the home page, you will be able to find what you are looking for through them. Plus you get a discount for being a member here.

 

Try to get some 95-98 headers and pick up some power.

 

Not really. The 99-04 exhaust manifolds are some of the best ford ever produced, they are not restricting until arround 300hp.

 

okay well the 99-04 ones are ok but the 94-98 headers are a lot better made and will flow better
i just switched to them and they are a great replacement for a cracked stock manifold

 

thanks for the info
