Renntech releases Mercedes SLS AMG long tube headers, +20 horsepower, $8200Renntech has released their Mercedes SLS AMG long tube headers. They don't come cheap, MSRP being $8200. They seem to be a quality piece that is ceramic coated. Power claims are 20 horsepower and 20 pound-feet of torque but there are no dyno or performance numbers to substantiate any power claims. The headers include 200 cell sport cats and we wonder what the gains and price would be without the integrated cats.
