MK3 Headers, worth it?

I was browsing around for some simple mods for my 98 Jetta GLX VR6. I found some headers that seam like it would be a fairly easy bolt on job. I have access to hoists, and all that at my school. Just wondering if anyone has put on headers and actually found a performance gain? Did fuel mileage decrease? etc.

Ah ic. I know with things like my snowmobile the equivilant of a header makes a huge differnce, but then again its just comparing apples to oranges. Does anyone have sound issues with them? I know on my VR6 I have a gutted cat and then a muffler, its loud, like really loud, around 95 decibels just driving down the highway. Will this make it louder?

Yeah headers will make it louder, there isnt really any power gains to be had. You need to buy good quality headers too, or you risk cracking the headers. Apparently Brospeed are good. I would invest your money elsewhere, the stock ones are already tuned for pretty decent flow.
