Euro-tuners are making more power with performance mods like cold air intakes and MagnaFlow cat-back systems. MagnaFlow?s VW Beetle, Golf and Jetta systems feature 2.25? fast-flowing mandrel-bent stainless steel tubing, a straight-through stainless steel MagnaFlow Performance resonator, a MagnaFlow Performance Muffler, and a polished set of stainless steel rear exit tips. These VW systems look good, sound good and add up to to an extra 21.9 horsepower and 18.8 ft.-lbs. of torque for the 1.8L Jetta.
