Enhance the sound and performance of your classic muscle car with the MagnaFlow Street Series Crossmember-Back Performance Exhaust System, part number mag15894. Designed specifically for vehicles like the 1968-1973 Pontiac GTO and select GM A-Body models, this system offers a deep, resonant exhaust note that balances aggressive sound with moderate exterior and mild interior noise levels. Crafted from durable, corrosion-resistant stainless steel, it ensures long-lasting performance even under demanding driving conditions. The crossmember-back layout replaces the exhaust from the crossmember on back, providing a straightforward upgrade that maintains a factory-like fit and finish. Featuring mandrel-bent 2.5-inch main piping and two straight-through mufflers, this system delivers improved exhaust flow and horsepower gains validated by dyno testing. The polished, weld-on 2.75-inch single-wall turndown tips with multiple exit options add a custom touch and enhance exhaust aesthetics. Extensive 3D scanning during development results in a direct-fit design that simplifies installation, allowing for DIY setup without the need for extensive modifications. Manufactured with CNC precision robotic techniques, the MagnaFlow mag15894 system combines quality craftsmanship with performance reliability, backed by a limited lifetime warranty. This exhaust system is an ideal upgrade for muscle car enthusiasts seeking improved sound, performance, and durability from their vehicle's exhaust setup.
