Exhaust System, Hooker, 1986-87 Monte Carlo/Grand National, 2.5" Cat-Back

1986-87 Buick Grand National/Chevrolet Monte Carlo SS Exhaust, (Cat-Back), by Hooker Headers®

Hooker Headers® cat-back exhaust brings a deeper street-machine sound to the G-body.

Give the Grand National or Monte Carlo SS a stronger street-machine voice with this Hooker Headers® cat-back system. Designed to connect behind the factory catalytic converter, it replaces the rear exhaust with a dual-outlet layout and turbo-style mufflers for a deeper performance sound. The system is intended for the factory four-bolt converter connection used by the listed applications. Its formed tubing and matched rear sections provide a coordinated installation rather than a collection of universal pieces. Retain the original catalytic converter and follow the installation instructions when positioning the pipes and hangers for axle, suspension and body clearance.
