the stainless 16v header build

[alex g]

[QUOTE=blackgti1.8]Nice work mate. They reckon that headers are not as hard as they look, but I've never suscribed to that theory
Very long secondaries - much longer than I've seen before.
Is this your own design, or is it a published spec?

yer they aint that easy, in theory they are but anyone who has had experience with metal warping and stretching and distorting through welding will know that lining up so many cuts and angles in a small area is quite hard.

the design was inspired by all the headers i could find out there it takes areas from a lot of systems, the long secondaries are similar to track style extractors and a little like the supersprint, i wanted to get some flex in ther so there was no chance of cracking.

it is going straight into a 2 1/2 in system with a backbox, does anyone have any reccomendations for a stainless backbox

Measure the size of the space available for the backbox, space is very tight on a Mk1. Just got to that stage with my project and couldn`t use the original box I wanted.

Headers look great man. I love the twin flexpipe

Awesome work!! They'll sound rather fine

Just a question.....You could have gone 4 into 1 but went for 4 into 2 into 1. Why?

4 into 2 into 1 are supposedly best for a road car - better spread of torque,
or at least that's what I've heard. 4 into 1 (I think) can give you more power, they need to be tuned carefully, because they come in at over a narrow band of RPM.
Maybe dubstarmk2 might like to comment on this...

Bump this up for big respect on this DIY.

Where did these end up Al and how did they perform?

[alex g]

finished them many moons back,still sitting in thr garge waiting for the inevatable

[mikinoz]

Name your price and you can see how they go on my car!

Seriously though, that is some amazing work. Whats the go with the RHD exit on the muffler? What is the thinking there, I may need to head to your thread to check out what you were planning. (or you bolted it up back to front! )

[alex g]

Side exit mik just in front of the rear rhs wheel

Did I mention I notched the sill so it sits nice and high a tight, and made my take on arch spats that double as heat shields
