I've been toying with the idea of putting raceland headers on my 99 M3. Aside from noises are there any more benifits from them?

Raceland headers worth it?

The headers themselves bolted up to the exhaust side of the head without too much trouble, but the downpipe portion of the header (bank 1 and bank 2) were coming into contact with each other. I didn't want to deal with that, so I ended up ditching those headers.
Another thing to keep in mind is they are based on the EURO M3 exhaust - so the flanges are different. It is a two bolt flange instead of the US model three bolt flange. Not a big deal, just have your local exhaust shop use two bolt flanges or V- Band's for your midpipe.
My advice: get some used euro headers, or pony up for some name-brand headers like Supersprint or Krommer Kraft (if you can find them).
I hope this helps..

They seem like decent headers on paper, but I could not get mine to fit properly.. Maybe I had a bad batch, or they were damaged in shipping?

Yes, I have installed several sets on supercharged setups. They don't really do much. You'll find that if you call up Turner, they'll tell you the same thing and actually talk you out of buying them.

The SuperSprint Euro fitment is so-so. I installed the end-to-end SuperSprint Euro setup. The biggest problem I had is where the header mates to the midpipe. The flanges (welded in place) do not align well.
You also need to do some minor grinding of the head where the header copper plugs get installed. Also, you'll need to source the copper bolts. You might find that the stock O2 sensor is not long enough to reach the connection at the valve cover/fuel rail as well. I ended up adding some length to both both O2 sensors for bank 1 & 2. Once installed they are very nice. Took me a while to get them installed properly.
