Spent a couple of hours on it last night, got the Alternator back on, and cut the stock system.
Not sure who's car this manifold was fitted to, or who had fitted it?
The pipe needs bending away from the sump, but also down wards as it rests on the sub frame.
The Oxyacetylene is buried in my mates van, and TBH we didn't fancy trying to get everything lined up correctly in the dark.

Plan is (on Sunday) remove the stock front section from behind the Cat', weld the flexi here and the rear section of the raceland pipe to the Cat pipe.

Then bend the manifold down pipe into shape.
Tried tonight with a scaffolding bar, but the engine mounts were taking most of the force!

Damn, my plan was to spend sunday wrapping the manifold up...but due to me entering my home postcode by mistake when i sent it to the work address, i've got to wait till saturday next week now!

Its annoying being an impatient person, isnt it!? :lol:

OK all fitted.
Had some serious issues to fit it right.

Before I fitted it, I wrapped the manifold. Id managed to wrap it in three sections.

When I fitted it and lined up the stock system it was clear it would fowl the sub frame.
So I had to cut the heat wrap at the bend so I could heat it and bend it.

I then stainless welded a stainless flexi an inch past the manifolds flexi mount.
This sits just under the sub frame.

After marking out the stock pipe, the Cat' was removed and the stainless welded to the Cat'
This way its nice and easy to remove if needed.
Much better than sleeving it IMO.

The wiring for the lambda probe was extended by metre (5 wires) by soldering and heat shrink on each section.
This was probably the most time consuming part!
I fed the cable up past the drive shaft, and following the existing wiring.

Need to get some more heat wrap, as theres a large section that was removed, and its tappy around the flexi section.

Really pleased with it.
The sound is a lot more raw than standard, it wouldn't be for everyone.
Performance wise, I love it.
Second gear is ace, the speed it eats the revs, and you can really feel the cam change over now.
It feels like an old school turbo hot hatch!

The video posted was recorded tonight a +2 degrees C.
The clips of the car when stock were at +4 degrees C.
Both clips were taken on wet roads.
The car is on 16" rims, and has a lot of weight in the boot, so the time are there purely to show the difference between the stock race land manifold.
I know its not the most scientific test, but still.

Stock.
0 - 60mph 9.17 Seconds
20 - 80mph 18.11 Seconds

Race land.
0 - 60mph 9.10 Seconds
20 - 80mph 15.23



Stock Manifold Vs Raceland Manifold

I think the sound is a great improvement - I want one!! :D

Is that your youngun spluttering a little on the Raceland 20-80 run or is it a by-product of the new manifold at that point in the rev range? :wink:

Well done mate :)

I know now how they can be made so cheap.
The stainless is very thin so sounds a little rastpy.
Great if like me, you like that sound.
But anyone who likes an OE sound I could imagen it could be annoying.

Great work on the manifold mate, hat off to you.

Are you going to the club polo RR day by any chance?

Ooh I wasn't aware of one.
Will take a look and may come down for the crack if its localish.

Reason I took the vid rather than rolling roads were I trust how the rev counter looks more than an unaccrate rolling road.
Wouldn't mind hearing the car on full felt though :D

Cant see it all that well, but its different to yours.
sorry to hijack, but does anyone know if the strut braces for the gti will fit lower models? e.g. 1.4 8v?
