I have been searching for a new set of headers for my beast for a bit and it appears that the guy at Evolve Automotive have as solution that has shown "very satisfactory" gains and is cost effective. From what I have gathered thus far, they are planning on releasing a catted and a de-catted version of the headers (Evolve please correct me if I am wrong). Putting out a poll to see if anyone is intersted in trying to get a group buy going so that we can all save a bit of dough. Current pricing on the headers is ~$3,600. With a group buy consisting of 5+ people, an additional 15% can be taken off the final price. More info (dyno and pics) can be found at http://www.m5board.com/vbulletin/e6...53-evolve-rs-headers-e60-m5-exhaust-info.html.
