The Revolution RS for the Honda S2000 features full 2.5 inch diameter piping for superior performance. The purposeful single-sided cat-back layout with minimal bends produces an effective but light-weight system. Careful attention to hanger locations makes it compatible with both AP1 and AP2 chassis. The extra large GReddy resonator controls unwanted drone, that is typically associated with larger diameter S2000 systems. Like all GReddy Revolution RS systems the fully hand-welded 304 Stainless-Steel exhaust carries a Limited Lifetime Warranty.
