It depends on what you want to do and what kind of supporting mods you have or going to have.

If you are going for sound it will only make a real difference if you have a full exhaust as well. If you have headers installed and leave the factory muffler and resonator on then there won't be a huge change in the sound of the exhaust note.

If you are going the performance route you will want a catback exhaust to compliment the header. Pretty much any muffler shop can build you one and it will allow the exhaust gases to flow much freer. I would also look at adding a freer flowing intake / M50 inlet manifold to free your engines breathing up altogether. However, if you want to go the extreme route you could always supercharge and have yourself some fun.

Headers alone won't make a difference but with support mods you can make an improvement in the sound of your car and performance.

Yeah, that is very true and I should have thought about asking if it was a 6pot or 8pot.

If you have a supercharged V8 at around 6psi, it'll add around 50 hp.

You won't get the kind of results out of headers on a BMW engine that you would on, say, an LS1 or similar American muscle. In addition, headers for a BMW engine are usually rather pricey. Dinan headers for the V8 are over $10K. Supersprint are more reasonable, but have a reputation for cracking.
