Has anyone got a new manifold from Greddy after there cast iron cracked. I had mine a little over a year and it cracked down the middle.

 

If you read through the Greddy thread, a lot of people have had their manifolds crack on them. Some people have had it happen more than once.

I think the most popular replacement right now is here: http://www.pfabrications.com/inc/sdetail/2040
It is supposed to be much stronger than the Greddy manifold, though they recommend you retune your car if you install this.

 

Thanks.... I'm gonna try and see if they will warranty the manifold first before i do anything.

 

I have one for sale, dont have pictures now but can take some after work, its used. PM me if interested after greddy says they won't warranty like they did to me (after wasting 4 weeks of my time)

 

Just by the pfab mani

 

Its tubular, i don't want it to crack again.

 

Damn how does cast iron crack?

 

That's what i said!

 

x2!!!

 

When i had the Greddy turbo kit on my car I thought that with the P-FAB manifold I wouldnt have to worry about the manifold cracking. That was not the case though. Within 1500 miles the manifold started to crack along the welds in two different spots. Bottom line... You need to have a flex pipe welded into the down pipe.
