The MagnaFlow Street Series cat-back 16672 brings a resonant, powerful tone and dyno-proven flow to compatible SUVs, using mandrel-bent 3in main piping and a single straight-through muffler. It exits at the passenger-side rear with 3.5×5.5in polished welded double-wall straight-cut rolled-edge tips. The system replaces stock components rearward of the catalytic converter, is CNC-produced from corrosion-resistant stainless steel and engineered for direct-fit installation.
