American Racing Headers is a great example of what culminates when highly skilled fabricators, with a complete understanding of motorsports and the science behind the parts they create, come together to take on a new world of high performance.
Taking the Bull by the Horns approach, American Racing Headers was formed to prove that superior quality and outstanding performance can and will be the keys to success. A staff with 40 plus years of combined high performance exhaust fabrication experience see to it that only the finest components and craftsmanship go into every header system.
Mercedes has always been a leader in styling, comfort, and performance. But when performance is top priority, you'd be hard pressed to find anything as awesome as the CLK63. By adding an ARH long tube header system to your CLK63, expect to unleash a minimum of 35-40 additional Rear Wheel Horse Power (before tuning). ARH direct fit, 100% U.S. made, 304 stainless steel header system is exactly what's needed to eliminate extremely restricted exhaust manifolds.
Features include: 1-7/8 inch long primaries, 3/8 inch thick laser cut flanges with tig welded hand ported inlets, leak free merge collectors with scavenger spikes, 200 cell metallic substrate cats and a direct fit 3 inch X-pipe that provides excellent ground clearance and great fit.
