1. Before starting work, familiarize yourself with the installation procedure by reading all of the instructions. 2. The exploded view (Figure 2) provides only general guidance. Refer to each step and section diagram in this manual for proper instruction. 3. Throughout this manual, the left side of the vehicle refers to the driver’s side, and the right side to the passenger’s side. 4. Disconnect the negative (ground) cable from the battery (or batteries, if there are two) before beginning work. 5. Route and tie wires and hoses a minimum of 6″ away from exhaust heat, moving parts and sharp edges. clearance of 8″ or more is recommended where possible. 6. When raising the vehicle, support it on properly weight-rated safety stands, ramps or a commercial hoist. Follow the manufacturer’s safety precautions. Take care to balance the vehicle to prevent it from slipping or falling. When using ramps, be sure the front wheels are centered squarely on the topsides; put the transmission in park; set the hand brake; and place blocks behind the rear wheels. Caution! Do not use floor jacks to support the vehicle while working under it. Do not raise the vehicle onto concrete blocks, masonry or any other item not intended specifically for this use. 7. During installation, keep the work area clean. Do not allow anything to be dropped into intake, exhaust, or lubrication system components while performing the installation, as foreign objects will cause immediate engine damage upon start-up. Tools Required: • 1? 2 ” and 3? 8 ” drive ratchets with standard and metric sockets and 1 ? 2 ” and 3? 8 ” drive extension • Standard and metric combination or open-end wrenches • Standard screwdriver • Clean shop towels or rags • Pry-bar Highly recommended tools and supplies: • Foot-pound torque wrench • Penetrating oil or light lubricant spray General Installation Practices 97083 v.2.0 3 Monster Exhaust SySTEM INSTallaTIoN 1. Disconnect the negative (ground) cable from the battery (if there is more than one battery, disconnect both negative cables). Secure the cable so it cannot accidentally come in contact with the post. 2. Raise the vehicle and support it securely with properly weight-rated safety stands, ramps or a commercial hoist. Take care to balance the vehicle to prevent it from slipping or falling. When using ramps, be sure the wheels are centered squarely on the topsides. Place the transmission in park (automatic), set the parking brake and securely block the wheels that are on the ground. CaUTIoN: Do NoT WoRK UNDER aNy VEHIClE SUPPoRTED oNly By a JaCK. SEVERE INJURy May RESUlT. 3. From under the vehicle remove the factory exhaust starting at the 2-bolt flange in front of the muffler. Remove the two (2) bolts, two (2) washers, and two (2) springs from the flange and retain for re-use. NOTE: Remove the factory gasket from the 2-bolt flange. The exhaust system will be hanging by the exhaust hanger pins. 4. Liberally apply an aerosol lubricant on all the hanger pins. Remove the exhaust system from the vehicle by removing each hanger pin from the rubber grommet. NOTE: Remove hanger pins from the front of the vehicle to the rear. 5. Drop the exhaust system to the floor and move out of the way. You will not be reusing any components from the exhaust system. 6. Install the Banks conical gasket onto the vehicle’s 2-bolt flange. 7. Install the hanger pin on the intermediate pipe into the corresponding rubber grommet. Install the Banks intermediate pipe onto the factory 2-bolt intermediate pipe outlet using the factory hardware.

Carbureted Fuel System GENERAL INFORMATION On these vehicles, the engine management system is considered part of the emission control system. The major components include the carburetor(s), feedback control system, the air injection system, a throttle control system and the EGR system. The system consists of sensors and switches that feed information to the Electronic Control Unit (ECU), which will then operate several solenoid valves to maintain the ideal air/fuel ratio under all conditions. As useful as the tests found in this section are, the first step in repair or service to engine management systems is still to gain as much information as possible about the problem; when and under what conditions it occurs. At highway speed? At idle only? Only under heavy load or hard acceleration? Wet weather? Defining the problem will eliminate many systems from consideration and possibly point to the affected system. Before diving into an extended electrical diagnosis, take the time to review the basics. Check every vacuum line for cracks or leaks. Check every electrical connector for corrosion or loose pins. Quite often, simply unplugging and reconnecting a connector will break up corrosion on the pins and restore the circuit. Watch out for poor grounds, particularly if the car has experienced major bodywork. COMPONENT TESTING Air Injection System The purpose of this system is to supply oxygen to the exhaust stream at a point in the exhaust manifold that is hot enough to burn off some of the hydrocarbon emissions. The main component is an air suction valve. The valve is spring loaded to stay closed, with engine vacuum supplied to a diaphragm that reduces the spring pressure and allows the reeds to open. The ECU regulates the engine vacuum to the diaphragm by operating a solenoid valve. 1. With the engine at normal operating temperature and at idle, remove the air cleaner and listen for a bubbling sound at the air suction port. There should be no sound at idle, meaning the air suction valve is closed. 2. If the noise is heard at the air suction port, disconnect the vacuum hose at the air suction valve and connect a vacuum gauge to the hose. There should be no vacuum. If there is vacuum and the noise stops, the problem is in the control system. If there is no vacuum and the bubbling sound is still there, the air suction valve is defective and must be replaced. 3. To test the valve, draw a vacuum at the air suction valve diaphragm and listen for a bubbling sound at the air suction port. If no sound is heard, the air suction valve or diaphragm is faulty.

NOTE: Be sure plug threads smoothly into cylinder head and is fully seated. Use a thread chaser if necessary to clean threads in cylinder head. Cross- threading or failing to fully seat spark plug can cause overheating of plug, exhaust blow-by, or thread damage. Follow the recommended torque specifications carefully. Over or under-tightening can also cause severe damage to engine or spark plug. 2. Install the spark plugs to the engine. Tighten: Tighten the spark plugs to 25 N.m (18 lb ft). 3.
