Got a crack on Greedy exhaust manifold
Hi I was wondering if anyone else had this problem.
My greedy exhaust mafifold which has ceramic coating got a crack between the last two cilinders. I will try to see if they will be covered by warranty.
Has anyone else notice if their manifolds are still intact?

I saw a greddy tt'd G35 at Performance Factory with this problem. I think the manifold was welded and it cracked again (this happened before it was brought into the shop). It was shooting out white smoke from under the hood but still making halfway decent power.

bump this up. was getting ready to ceramic coat my manifolds and other parts and noticed a crack between 3-5 on pass. manifold. dang crack is about 200 degrees around the whole diameter. brought it to my welder and he can't patch it without it cracking on cooldown. may need another one.
anyone else had luck with welding it and it staying sealed?

same happened to mine, i had one of the earlier kits. they replaced mine for like 200 bucks i think... i think it happened about 2.5 years later IIRC.
i wonder if they have made adjustments to their casting mold yet? they are aware of the issue and stock replacements, so i would assume they have tried to fix it by now?

no room to weld on the inside. found a place today that specializes in welding cast cylinder heads. they made me feel very positive that with their process it will never fail again (in that area atleast). seems that is the spot where most are cracking so, i should be good after the repair. they will also need to resurface the mounting flange when done and i guess their trick is letting the thing cool down over a 24 hour period. should be better than new. cost=$100

good luck with the warranty service. I've had bad luck with greddy products in the past. After so many failed products, I concluded they make poor quality products. No customer service either....
Exhaust rotted out from the inside out, spec II boost controller solenoid broke (leaking) after 3 months.. (took them over half a year to send me another one), Boost gauge needle was way off after a month of usage... they said "too bad."
