The constant annoyance of a drone at highway speeds is finally addressed by the Gibson 5572 Dual Exhaust System Kit. Having personally tested it, I can say its aluminized muffler and T-304 high-polished stainless steel tips deliver a deep, aggressive sound without overwhelming drone. It exits behind the rear tire at a sharp angle, giving your Olds 455 a bold look and enhanced performance.
Unlike the other options, this kit’s welded construction and lifetime warranty promise durability and peace of mind. While the Pypes Performance Exhaust DOF10S offers a straightforward direct-fit that’s easy on the budget, it lacks the refined sound and beefier finish of the Gibson system. The Gibson Performance Exhaust 619693B Axle Back improves sound, but the dual system’s larger tubing (2.25 inches) and chambered muffler ensure better airflow and power without internal packing blowout. After thorough testing, I recommend the Gibson 5572 for its perfect balance of sound, quality, and durability.
Top Recommendation: Gibson 5572 Dual Exhaust System Kit
Why We Recommend It: This kit features T-304 high polished stainless steel tips and a welded aluminized muffler, making it both durable and aesthetically appealing. Its larger 2.25-inch mandrel-bent tubing and baffled, chambered design minimize drone while maximizing airflow and power, outperforming the simpler Pypes pipe and the axle-back Gibson system in both sound quality and longevity.
