Gibson 05-06 Pontiac GTO Base 6.0L 2.5in Axle-Back Dual Exhaust - Stainless

The Gibson 618000 axle-back exhaust system is built for your 2005-2006 Pontiac GTO with the 6.0L engine. This system uses a baffled and chambered muffler design, meaning it tunes the exhaust note using resonance chambers and directional louvered ports. This advanced design helps draw exhaust gases into the muffler and expel them at a higher velocity, which can lead to improved acceleration and a more aggressive exhaust rumble without excessive interior drone. It's a solid option if you're looking to get more out of your GTO's performance sound.

Constructed from stainless steel, the tubing is mandrel-bent to ensure consistent diameter throughout, which helps maintain smooth exhaust flow. The dual slash-cut tips are polished and double-walled for a clean, finished look. Gibson includes all the necessary hardware and factory-style hangers for a hassle-free, bolt-on installation. This means you can typically get this system installed without needing to cut or weld, making it a straightforward upgrade for your GTO.

This axle-back system is designed to bolt directly to your existing cat-back exhaust, making it a focused upgrade for the rear section. Gibson backs this exhaust system with a Lifetime Limited Warranty, giving you confidence in its durability and performance for years to come.
