S. COMP STK DUAL GN

The Hooker 16810HKR Super Competition Cat-Back Exhaust System is engineered to deliver enhanced performance and a distinctive exhaust sound for 1986-1987 Buick Grand National and Monte Carlo SS models. This system utilizes 2.5-inch mandrel-bent, 16-gauge aluminized steel tubing, ensuring consistent inside diameter and maximum exhaust flow. It includes all necessary tubing, head pipes, dual turbo mufflers, tailpipes, and hardware for a straightforward installation. The system is designed to bolt directly to the factory 4-bolt catalytic converter outlet flange and exits at the stock locations, utilizing existing stock hangers for easy installation. The un-coated aluminized finish provides durability and long life. Hooker recommends using this system with their Aero Chamber Series muffler # 21502HKR for optimal results.
