Z22Se 4-2-1 Exhaust - Manzo Brand, Initial Photos
Posted 10 October 2020 - 09:06 PM
Following the chronology it would appear that this Manzo brand one is a 'homage' to the Weapon-R exhaust.
Most importantly for me the trickiest fabrication was done - the manifold itself (4-2 part)- and I can handle the downpipe (2-1 part) and the cat etc. myself.
The following photos are mostly without commentary, but i'll answer questions if there are any.

All in all worth the money to use as a base, but you get what you pay for.

Interesting design. I had a crack at making a manifold many years ago. not welded for 10+ years and it was a proper abortion of a job! Needed a bit more practice before I started! I suspect this one would foul the clam as it looks to project from the engine a fair way but I like the 4-2-1 design of it. The collectors look a bit gash but as you say it could be price driven. Switch these out for a hydroformed collector and it'd be far better. Inside pics look on par with what I made

My constraints are that I don't want to change my backbox and need a cat, so I only need to deal with the in-between bits.
The collectors can be accessed by my long die grinder and I have a factory full of qualified welders who are more interested in having a look at it than doing their actual work.
Now that I have the ability to edit the ECU maps i'm sure I can squeeze something out of it.

You need to cut into the boot to fit this 👍.
My car produced good torque with this manifold compared to similar spec cars with a 4-1 manifold.

I have a new engine coming, so I am waiting until that arrives to help me mock up where the cut out needs to be.

Many years ago some swedish people did the Weapon R thing.
I found the thread but most of the pictures are gone.
On page 11 there is still a picture of the cut-out and the heatshielding he made up.
Oh, it is all in swedish.

I've mined the available pictures from the thread. That will help a lot.

Danke für die weblinks. Ich werde ein konto erstellen, um auf das forum zugreifen.
Here are new fitment photos done on a new engine i received so that people can see the manifold without a car around it. (click for bigger)
