This Borla Performance Cat-Back™ Exhaust System (Part number 140105) has been designed for 2002-2005 Nissan Altima equipped with a 3.5L V-6 engine and automatic or manual transmissions. Borla Performance Industries recommends that an exhaust shop or professional after market parts installer, who has all the necessary equipment, tools and experienced personnel needed for proper installation, should perform the installation of this system. However, if you decide to perform the installation, we recommend someone should help you. Ensure the installer uses all under car safety precautions including eye protection.

Original Exhaust System Removal
Note: With a used vehicle, we suggest a penetrating spray lubricant to be applied liberally to all exhaust fasteners and allowing a significant period of time for the chemical to lubricate the threads before attempting to disassemble.
1. Remove the ground strap shown in figure 1 located on the right rear muffler.
2. Unbolt and remove the center support bar shown in figure 2 located just behind the front muffler.
3. Unbolt the flange shown in figure 3 located just ahead of the front muffler. Place the hardware and gasket to the side for use during the installation of your new exhaust system.
4. Lubricate all hangers and rubber isolators.
5. Using a muffler stand or an additional person to hold the exhaust system up in place, remove the hangers from the rubber isolators and remove the exhaust system from the vehicle.
