"HERE IT IS"

CF2 and CF3 manifold

The manifold fits both models, The only differance is the CF3 has 2 lambda ports in the primary collectors.

The flexi sections are different on both models, but are designed to be a replacable part ( encase the flexi breaks )

100% TIG welded, not a MIG weld in sight.

Laser cut flanges

CNC mandrel bent pipes.

Pipe lengths and diameters are designed for low down torque and a smoother torque curve right through the rev range.

The CF2 and CF3 are the same price, £400 inc postage.

As they are made to order, there will be a small leed time.

If you are interested, contact me at:
[email protected] or on the forum.

The idea behind the replaceble flexi was my suggestion :) Wish the Mrs would let me buy the kit, think i have a crack in mine. I'll have to sweet talk her cos it looks like a great piece of work.

Love the fish scale welds. Only seen them on high end Jap stuff. Very nice!

Mate, and what a good suggestion it was. It also ment I could make the main part of the manifold to fit both models and make different tail sections that just bolt on. It's worked out good for everyone:cool:

Shame I already got the Supersprint one fitted :D

I do wonder though how much different torque curves would be between the two as it looks like good quality work.

Did you base your design on any existing well known manufacturer's? i.e. benefiting from someone else's R&D as I would have done..... :D

Mate, where do I start. For starters I work at a well known exhauts manufacturer. We specialise in motor sport exhausts. I've made exhausts on so many cars it's not funny. A small list.

Caparo t1 development
Radicals ( all of them )
Ultima ( all production manifolds and systems )
GT40
lola t280
lola t70
Ascari kz1's
ascari A10
pre-war and modern aston martins
caterhams
Ariel atoms
Ferraris
Porches
Lots of single seaters

The list goes on and on

In the exhaust world there are some standard rules, but exceptions as well.
The Over all manifold length for 4-2-1 and 4-1 is around 39",for a 4-2-1 it depends on how the length gets diveded up. For getting power in different areas in the rev range u change primary and secondary lengths and diameters, this comes with years of practice, and making lots of dino manifolds for lots of different engine developers and tuners, e,g cosworth. My self, I've got 10 years experiance. Thats a lot of custom exhausts

So the answer is, no, I didn't copy someone elses manifold

Nice list of projects there fella :D

Are you able to do unsilenced center sections and backboxes??

I don't at the mo for the 156, but as soon as I do one on my car I'll be good for it. It you need anything and can send me the part to jig I can sort it out.

It looks great!!! I have replaced my euro3 manifold (with the pre-cats) with a euro2 manifold from an 156 and the noise is disturbing!!! I can't drive it like this any more...my nerves:rant:!!!
I am thinking of replacing the euro2 manifold to get rid of the noise so I'm searching for the replacement...is this manifold noisy??(a have a supersprint exhaust and a custom middle section...) What's the pipes diameter??

edit: I have an 147 2,0 ts

No the manifold isnt noisy, its got a good note. The primarys( 4 pipes ) are 1 5/8"(41mm) and the secondarys( 2 pipes) are 1 7/8"(48mm) and the system is 2 3/8"( 60mm ) The only thing is, i didnt know the tail flanges are the same on a 147 and a cf2 156 manifold, Are they? as you have put one on your 147. It would be real nice if they are:) There is another post( wizrdovoz manifold ) from someone that got one from me, take a look. He could'nt say enough good things about it. I would think s/s do a center section.

Νo the flanges are different between the cf2 156 manifold and cf3 147 manifold...I took the cf2 156 manifold, I cut the pipe and weld it to match with the 147 pipe, just before the flange to the catalytic converter. But I think that the cf3 156 and cf3 147 manifolds are the same...as I can see from the pictures I can't spot any difference!

that would be smallvilles 1.6 147, its top notch work fella:thumbs:

The difference between the cf2 and cf3 is, the 2's cat inlet is straight and the 3's is on an angle. If you want one just let me know. I have heaps of pics of my work if you want to see what standards I work to.
