The photos below are of the raw catless downpipes we are designing for the new V8 Bi-Turbo Mercedes CLS63.  The components are being fabricated and prototyped on this white 2012 Mercedes CLS63. One unique step in particular is the creation of a ball joint that will allow the you to bolt this directly to your factory exhaust.  With an ECU Flash alone putting this over 700ft/lbs of torque, these downpipes will largely increase that as well as turbo spool giving this CLS63 a demon life.  Stay tuned for more developments soon!
