2.5 manifold question

[ecosnige]

Hi just looking at the thread u proberly guessed it was cracked is there a definate answer to replacements?
Id much prefer to get new or alternative exhaust rather than weld and advice welcome.

Take it to your local weld shop and get them to repair it but also add some bracing top and bottom across the flanges. No point in repairing it only back to its too weak state.

As Paul, says I paid the guy some beer money and he was happy!! Looks ugly but must be a whole lot stronger!!

Just had mine welded top and bottom. It seems to be holding up ok

Would the m400 manifolds fit????? i had a look at a 3r and they look identical what are the manifold diferences?could i have a m400 one modded to fit if it is slightly diff??Also one more q here how much are m400 manifolds i was sure i read they are very reasonable im more than likly wrong lol.

M400 manifolds are around £140 each IIRC.

M400 manifolds are not a panacea, they can crack also..Mine did.

I thought the 2.5 and 3.0 manifolds are different. If so, the M400 ones will not fit. Perhaps someone can confirm this?

[ecosnige]

I realise the m400 one might crack also but i heard its double skinned ??my 2.5 and a 3r i seen looked exactly the same tbh if the angle of the engines is the same ie the block hasent changed at all then i cant see why it would not fit surly this would be a great replacerment for cracked older manifolds seeing as there only 140 each??long life wanted 200 to weld mine up.So im thinking get some new m400 ones get them welded before i fit to make extra strong and fit lol.There is soo many posts about manifolds there must be a answer instead of a short fix that has broke on mine a few times.I have recipts for welding on manifold.

I asked the factory and apparently the stud patterns are different between the 2.5 & 3.0 manifolds. It looks as though having buttresses welded top and bottom is the way forward, as suggested above.

hi where do you get the manifolds from for the 2.5 as i want both. Is there a contact number or email. many Thanks, sorry for the thread hi jack

Have you tried Noble, bet they're cheaper than you think, i read on here that someone charged more to repair cracked one than Noble charge for new.

They never replied to my emails, so just assumed they didn't sell parts and that it was a different email for parts

Telephone Noble and ask for Bill. They were £80 each.
