WANTED 3.0si front exhaust manifold w/ cat

[Astonyeah]

Need a new front exhaust manifold with cat as mine has bit the bullet! For the right price would take both front and back for balance’s sake.

Front 18407511674
Back 18407560907

Located in West Berkshire.

Cheers all

If I can ask, how different or what are the differences between a 3.0si manifold and that off a 2.2, 2.5 or 3.0i?

 

[Astonyeah]

No idea! The part number on realoem fits all N52 Z4s (inc 2.5i and 2.5si), but is different for M54s - all I can seem to find for sale is for M54s! I figure the shape or something is different, who knows?

I only ask as I have one available

FYI,

Have you considered trying to rejuvinate your cat? Citric acid + oxalic acid. Sounds like voodoo but the science is real. Here are some quick links but some detailed searching should help:

Hadn’t considered that cheers, it may be a possibility on my bank two, but bank one is FUBAR - see thread link in my OP!

No part number as I've never seen one on a manifold.

Just the one picture. It's not the greatest.
I'm sure I toop pictures last weekend but I can't find them. I'll get better this weekend whilst I'm home. I work away.

Nice one cheers man, I’ll have a look tomorrow in the light and yeah some more pics would be great, when you can please

Got one sourced. Cheers all. Now to get it fitted! Anyone know if the rear bank needs to come off as well or can the front be jimmied off with the rear still mounted?
