Mercedes 2007-2009 E63 / CLS63

It took one good look at the Mercedes E63 and CLS63 to realize there was huge power waiting to be unleashed and ARH went to work. The result was gains well over 30 RWHP and 35-40 RWTQ UNTUNED. Our 100% US made, 304 S/S header system is exactly what these powerful V8’s need. Features include 3/8” thick flanges with tig welded and hand ported inlets, 1-7/8” long tube primaries, leak free merge collectors with scavenger spikes, 200 cell metallic substrate cats (or cat delete) and a direct fit 3” X-pipe that provides excellent ground clearance and great fit. If you are an E63/CLS63 owner looking to make that one time purchase that makes a real performance difference, the ARH header system is it.
