These downpipes are THE best bang for the buck mod available for your B58 and they’re available in both race & high flow configurations. Back pressure is significantly reduced with our race or high flow 200 cell race cat which results in faster spool, an increase in power. There is a more aggressive exhaust note. This downpipe features a full 4.5″ stainless steel design as well as a CNC 304 grade stainless steel flange that offers a smooth transition from the turbo to the mid pipes. All VRSF downpipes are hand crafted from SS304 grade stainless steel and include a lifetime warranty as well as our “No Hassle” satisfaction guarantee (includes fitment). Please note that the warranty on the catted downpipe is limited to one year. Made from hand crafted, tig welded 4.5″ 304 grade stainless steel. Available with a 200 cell high flow cat (1 year warranty). Fits RHD and LHD models with no modification necessary. Smooth radius bends to decrease turbulence and increase flow. Fits the stock catback as well as all aftermarket catbacks. Gains from 25-30hp with tune. VRSF Lifetime Warranty for race versions, 1 year warranty for high flow catted versions.
