Installation Instructions for Chevrolet Cruze 1.4L Stage Kit

Quick guide from the manual

This kit is designed for 2012, 2013, and 2014 Chevrolet Cruze models with automatic or manual transmissions. Installation requires mechanical expertise and specific tools. Safety Warning: Never work on a hot exhaust system; allow the vehicle to cool for at least one hour. Always wear eye protection and use proper vehicle support (hoist or jack stands).

Required tools and supplies

• 3/8" Drive Ratchet
• 3/8" Drive Extension, 6"
• 13 mm socket
• 15 mm Socket
• Reciprocating saw/hacksaw
• Pry Bar
• Wire Brush
• Spray Lubricant

Original exhaust system removal

1. Apply penetrating spray lubricant to all exhaust fasteners and rubber isolators. Allow time for the chemical to work.
2. Use a 13mm socket to unbolt the flange and let the exhaust hang to provide clearance for cutting.
3. With a muffler stand or an assistant supporting the front muffler, cut the pipe at the designated location. Remove the hanger from the isolator and remove the front muffler.
4. Support the rear muffler assembly, remove the hangers from the rubber isolators, and remove the assembly. It may be necessary to remove the tip isolator bracket.

Exhaust system installation

Warning: Do not use air impact tools to tighten fasteners, as this may result in bent flanges or exhaust leaks. Torque all fasteners according to the manufacturer's values.

1. Using the provided hardware and new gasket, position the front pipe and hand-tighten the hardware.
2. Place a clamp over the expanded end of the intermediate pipe, position it, and install the hanger into the rubber isolator. Do not tighten the clamp yet.
3. Place a clamp over the expanded end of the rear muffler assembly, position it, and install the hangers into the rubber isolators. Do not tighten the clamp.
4. Place a clamp over the expanded end of the tailpipe assembly and set it into position. Do not tighten the clamp.
5. Tighten the front flange to 18-22 ft-lbs. Push the exhaust up to fit properly in the tunnel. Tighten all clamps from front to back to 32-35 ft-lbs.
6. Check for proper clearance under the vehicle. Adjust and re-torque as necessary.

Post-installation and calibration

Before starting the vehicle, ensure all wires, hoses, brake lines, body parts, and tires have safe clearance from the exhaust system. Start the vehicle and check for leaks. Drive the vehicle to a dealer to have the Engine Control Module (ECM) updated with the correct Stage Kit Calibration. Install the provided Emissions label in the engine compartment and the Premium Fuel Required label inside the gas cap access door. Note that smoke and fumes during the first start are normal due to the protective coating on the tubing and will disappear quickly.
