Please study these instructions carefully before installing your new Cat-Back Exhaust System. If you have any questions,
contact our Technical Hotline at: 1-800-416-8628 from 7 am - 5 pm, Monday through Friday, Pacific Standard Time

SUGGESTED TOOLS FOR INSTALLATION:
❑ 3/8" ratchet set with SAE and metric deep sockets
❑ Jackstands and jack
❑ Liquid penetrant and rubber lubricant
DISASSEMBLY
1. Raise vehicle and support with proper
jackstands for the weight, leaving the
suspension hanging.
2. Use caution around hot exhaust systems to
avoid burns.
3. Use penetrating oil on all nuts and bolts.
4. Measure 10” from the back of the factory Y-pipe
hanger bracket and cut the factory intermediate
pipe.
5. Remove the bolts and clamps from the system
and lubricate the rubber isolators to ease
removal.
6. Use a long pry bar to pull the rubber hangers out
of the OE insulators.
7. Remove the old system. In some cases, you will
find it easier to cut the overaxle pipe to remove
it.
WARNING: Exhaust gas contains carbon monoxide, a deadly invisible gas. Correct any leaks before
driving!
IMPORTANT NOTE:
Proper installation is the responsibility of the installer. Improper installation will void warranty and may
result in poor performance and engine or vehicle damage.
