Borla Performance X-Pipe Installation
1. Orient components on floor referencing page-2 drawing. (See Fig. 6)
2. Place a clamp over the expanded end of the X-Pipe assembly, and set it up
into position. (See Fig. 7) Do not tighten the clamp.
3. Using the original hardware insert bolts into the spring hangers and tighten
the bolts. (See Fig. 8)
4. Using the hardware that is provided insert the blots on R/H & L/H side
flanges and tighten the clamps. (See Fig. 9)
5. Check your exhaust system for proper clearance under the vehicle and also
for tip alignment. Starting at front flanges and moving to rear of vehicle,
tighten flange hardware bolts. Orient position of bolt (on supplied clamps)
between (not over) pipe notches and tighten to 35 ft. lbs. torque. (See Fig.
10)
6. Align tips and tighten hardware. Loosen clamps to rotate or slide pipe for
better alignment.
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 or incorrectly positioned clamp) and repair as neces-
sary.
Congratulations!!! You have completed the installation of the world famous
Borla Performance Stainless Steel Exhaust System.
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 coat-
ing 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 temper-
atures.
WARNING: Use extreme caution during installation. Torque all fasteners according to manufactur-
er’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.
