2005 Chevrolet Cobalt Exhaust System Installation

Borla Performance Cat-Back ™ Exhaust System Installation
1. Using the hardware supplied, place the front muffler assembly up into position as shown in figure 5 making sure to install the hangers into the rubber isolators. Hand tighten the hardware for now.
2. Place a clamp over the expanded end of the intermediate pipe and set it into position as shown in figure 6 installing the hanger into the rubber isolator. Do Not tighten the clamp.
3. Place a clamp over the expanded end of the rear muffler assembly and set it into position as shown in figure 7 making sure to install the hangers into the rubber isolators. Do Not tighten the clamp.
4. Check your exhaust system for proper clearance under the vehicle and also for tip alignment.
5. Once position has been determined to be correct, tighten the Accuseal™ clamps to 32-35 ft. lbs. and the flange hardware to 18-22 ft. lbs.
6. Before starting your vehicle, make sure to check all wires, hoses, brake lines, body parts and tires for safe clearance from the exhaust system.
7. Start vehicle and check for any leaks. If any leaks are found, determine cause (such as loose or incorrectly positioned clamp) and repair as necessary.
Note: When you first start your vehicle after the installation of your new Borla Performance Exhaust System, there may be some smoke and fumes coming from the system. This is a protective oil based coating used in the manufacturing of mandrel bent performance exhaust tubing. This is not a problem and will disappear within a very short period of time after the exhaust has reached normal operating temperatures.
