best headers for C55
#3
MBWorld Fanatic!
Evosport, Renntech and Kleeman make headers for the C55. I have the Evosport headers. They have been working great for me over the last 6 months. Search for my "progressive dyo results" thread. My dyno/tuner guy at ICS Stamford states Renntech & Evosport produce about the same gains, but the Renntech headers are higher quality stainless and hence much more expensive. Others on this forum have the Kleeman long headers and love them.
