Do you have both sides by chance?
I'll tell you from tons of experience on other vehicles the lower end headers are poop in quality. They'll be a rusted up mess in less than a year and headman in particular is good for having cheesy welds on it lower end products. They do help in power in most applications but as always I don't see them doing much for a Disco unless they are followed with high flow cats and a 2.5" dual system with a balance pipe. Not sure if there are even any other options for a Disco but I always expect to pay at least $400-$500 for a decent set of headers. The painted ones suck and get really hot, ceramic coated helps but you'll pay for it and again I'm not sure if such a product even exists.
If you want to get a little boost in umph and don't want to fool with headers, try porting your stock manifolds. Its easy to do and will often yield the same gains as headers on small displacement engines. There are tons of videos and how to online and even a first timer can be really successful if he/she doesn't rush things.
The factory manifolds aren't all that restrictive anyway, its all the garbage that follows them that chokes up the exhaust system.

They do have ceramic coated ones, they are about $500.
If I went the hedder route I was going to delete my cats and run a whole new custom exhaust, I know a shop that could do the whole thing, custom pipe bending and all, for about $125 plus mufflers.

If you wrap the cheap ones they cool off quite a bit, the main issue I've had with headman stuff is the welds breaking right at the manifold plate. That's mainly based on small block and big block GM applications but I imagine the same process is used welding all of their budget minded headers. $125 for the rest ain't bad, almost makes buying the ceramic coated ones worth it.

I have both, need to drill out studs. PM me and I;ll send you my email address. They are sitting in the scrap pile.. I'll pull them out and box them and get a quote.
