The MagnaFlow Street Series cat-back exhaust for 2005–2006 Pontiac GTO (6.0L) delivers a resonant, powerful tone and dyno-proven flow. It pairs mandrel-bent 2.5in main piping with straight-through mufflers and a dual split rear exit with 4in polished welded tips for a balanced sound and upgraded rear appearance. CNC precision manufacturing and 3D-scanned direct-fit engineering simplify installation while stainless construction resists corrosion.
