I was thinking of installing a set of exhaust headers for a little more sound/performance, but after searching, I'm really only seeing 2 options out there:

1) cheap ebay headers for about $100
2) something like supersprint for $1500+

In looking at realoem, it appears that the E53 and E39 use the same exhaust manifolds for the M54-equipped cars. However, all the ebay listings that list fitment for the E39 show the same part for the E46, which I understand will mate to the head but are too short and will need custom work to attach to the E53 stock exhaust.

Is there a decent quality bolt-on solution in between? I'm willing to spend more (not $1500), but even the few see for $5-600 appear to be the same cheap ebay headers for the E46 just at a higher price.
