So I'm another guy who has the famous cracked exhaust manifolds from Greddy.
Had the kit for about 10k miles and from what I can see the right one is the only cracked. My question is where is there a shop or person who may have a set? Greddy said the wait time is about 45 to 60 days. Is there another company who makes exhaust manifolds to fit the greddy kit? Also what have you guys done to prevent this matter from cracking again?

 

have it welded good

 

I'm thinking with the pita removing the engine might be better just to replace them. they are showing rust as well

 

Can you physically touch the cracks? Maybe they can be repaired in the car

 

Yeah I can touch them. Kind of tight but yes I touch them everyday. Everything is so tight and close so I'm worried with welding

 

I would take the time to remove them from the car...even if you just remove the front clip...you want to give a welder full access to make the repair. I would also have the other one inspected while your front clip is off. and I would also buy flex hose and have them installed to your cats/test pipes and/or on your exhaust to prevent this from happening again.

 

Tough decisions...

Keep us posted

 

I have flex hose on my test pipes. Think that is a must have for those headers because they are not so flexible like the stainless when hot. I have put all together (turbo to header, wastgate etc)before putting in car, have noticed that is very important to make flat all surfaces where the nuts come so when you fasten all must go easy. The factory molding is not so good finished.
If you remove the right motor mount you can tilt the engine to left and than you have much more space to work.
I would like to buy another ones cracked so I can make my own stainless headers. If anybody would like to sell let me know.

 

I just ordered a pair from Greddy about 2 weeks ago, they said it would take 4-6 weeks before I get them though.... I would like to also find an alternative to these Manifolds as well.....

 

 

4-6 weeks damn. I'm just going to have it welded then while I wait. Greddy sucks

 

thats only what sucks from Greddy

 

any word on where I can get a set of Greddy manifolds

 

^^^I'm gonna go with greddy...

 

yup nothing has changed since 2003 when greddy released the kit. Only place to get greddy manifolds is greddy. No alternative manifolds can be used.

 

thanks guys hopefully they have some in stock. is the greddy manifolds from the hr and de the same? they look the same

 

If you ordered them November 4th when you posted, you would have them by now!

Yes the HR/VHR/DE manifolds are all the same. Get them ordered while you can because that kit is discontinued and they might not even make more of them much longer.

As for the Greddy sucks comments... while they did make the manifolds a little thin in the area that they crack... its not a rare problem for cast turbo manifolds.

 

how much are the manifolds from Greddy?

 

If you have them welded make sure they use a copper nickel filler rod

 

I saw on GTM's website they sell them. Give them a call.
