Pontiac GTO Zeta Muffler Delete Axle Back Dual Black Tip Exhaust 2005-2006

Upgrade the exhaust sound and performance of your 2005–2006 Pontiac GTO with this T-304 stainless steel muffler delete axle-back exhaust system, engineered to deliver a more aggressive exhaust note while maintaining precise OEM-level fitment. This system transforms both sound and rear-end styling for a more performance-focused driving experience.

Designed specifically for the Pontiac GTO platform, this axle-back system replaces the factory mufflers with a straight-through configuration, improving exhaust flow and reducing restriction. The result is a deeper, louder, and more responsive exhaust tone that enhances the vehicle’s V8 character.

Constructed from premium T-304 stainless steel, this system provides excellent durability, corrosion resistance, and long-term reliability. Finished in anodized silver with dual black exhaust tips, it delivers a clean yet aggressive visual upgrade that complements the GTO’s performance styling.
