CTS Turbo race downpipe set for Mercedes Benz C43 C400 C450 E43 E400 E450 with M276 engine
Unlock the M276 3.0 twin-turbo V6 in your Mercedes-Benz with this CTS Turbo race downpipe set for the C43 AMG, C400, C450 AMG, E43 AMG, E400 and E450 AMG. CAD-engineered to fit perfectly in place of the restrictive factory catalytic converters, they are manufactured from cast T304 stainless steel, hand TIG-welded and back-purged for years of reliable service.
They also wake the car up: a louder, deeper growl with a much more pronounced crackle on downshift, and a confident punch as you bang through the gears. With an aftermarket exhaust already fitted, expect even more volume.
