2006-2008 Audi A3 Exhaust System Installation

Precision manufactured using aircraft quality T-304 stainless steel; this system is designed to endure years of heavy use. Installing a Borla Performance Exhaust System on your vehicle will eliminate the restrictive design of the stock exhaust, allowing your engine to discharge exhaust gas easier. The result is more horsepower and torque, longer engine life, and a distinctive throaty growl- all this, with easy bolt-on installation. These installation instructions have been written to help you in the installation of your Borla Performance Exhaust System. Please read it completely before installing your system.

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. Loosen the clamp shown in figure 1 located just ahead the front muffler.
2. Lubricate all the hangers and rubber isolators as the one shown in figure 2.
3. Using a muffler stand or an additional person to hold the exhaust system in position, remove all the hangers from the rubber isolators and remove the exhaust assembly from the vehicle. As shown in figure 3.
Warning: Use extreme caution during installation. Torque all fasteners according to manufacturer’s torque values and tightening sequence. DO NOT use air impact tools to tighten fasteners on Borla Performance Exhaust Systems. Use of such tools may result in bent flanges or gasket contact areas leading to exhaust leaks.

Borla Performance Cat-Back ™ Exhaust System Installation
1. Place a clamp over the expanded end of the front muffler 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 the rear muffler assembly and set it into position as shown in figure 5. Do Not tighten the clamps.
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.
