I assume it's yours I seen on jcwelds Facebook page

Ellis, just done a B8 RS4, they sound good!

Just noticed your avatar there broster. Damn I want one of those JCWF exhausts on my Audi, incredible noise they create.

with TP extrusions you usually need to order 1/2 a ton of material, which is just a little over 1m!

get some alu tube the right diameter and squash it in a vice between 2 bits of wood?

These chaps might advise although looks custom - their highest stock oval is 20mm which means you'd need it to be 106mm wide overall to retain that circumference. They only list 70mm which would only give a circ. of 162mm which is about 51mm round tube.

An actual ellipse or a radiused rectangle?

Or not fussed?

The latter being easier to work out dimensions as you've got a circumference that has more in common with a regular circle.

75mm dia hose has a circumference of 235mm

So at 45mm height you'd have a circ. of 141mm so would need to add 47mm of width so it'd be 92mm wide.

Columns are height, circ. and additional width, all mm.

Btw if you Search for eliptic thin wall mild steel tube, or words to that effect . You should find what you need

Okay only asking as I'll keep a lookout in work

Whats it for?

I'd need about a metre in total

How long do you need it to be?

Would be perfect if it was bigger

Electrical oval tube?

Could you take thin wall tube and press it? Wouldn't be scientific but it would probably be oval..

Really struggling with this but I'm after some oval tubing which will suit a 75mm round hose (I know that contradicts...)

Needs to be light and doesn't need to be strong so plastic/carbon/aluminium will all work but no steel/iron/granite please.

I could do with it being relatively flat too but I can't do the maths to work out heights/widths.

Any pointers?
