2007 Audi RS4 Exhaust System Installation

Borla Performance Cat-Back™ Exhaust System (Part number 140251) has been designed for the 2007 Audi RS4 equipped with 4.2L V8 engine, all-wheel drive 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.

Exhaust System Installation
1. Place a clamp over the expanded end of the front pipe assembly and set it into position as shown in figure 4 making sure to install the hangers into the rubber isolators. Do Not tighten the clamp.
2. Place a clamp over the expanded end of each mid muffler assembly and set them into position as shown in figure 5. Do Not tighten the clamps.
3. Place a clamp over the expanded end of each rear muffler assembly and set them into position as shown in figure 6 making sure to install the hangers into the rubber isolators. Do Not tighten the clamps.
4. Install the vacuum plug into each hose as shown in figure 7 and tuck the lines up and away from the exhaust.
5. Check your exhaust system for proper clearance under the vehicle and also for tip alignment.
6. Once position has been determined to be correct, tighten the Accuseal™ clamps to 32-35 ft. lbs. making sure the clamp opening is not over any of the notches in the pipe.
7. Before starting your vehicle, make sure to check all wires, hoses, brake lines, body parts and tires for safe clearance from the exhaust system.
8. Start vehicle and check for any leaks. If any leaks are found, determine cause (such as loose hardware 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.
