2007 Cadillac Escalade 6.2L AWD Cat-Back Dual Extreme Exhaust Installation Instructions
When installing this exhaust system make sure to use proper safety precautions. Use jack stands when working under the vehicle, set parking brake, block tires and use safety glasses and gloves. Allow exhaust to cool before attempting installation. Severe injury or burns could occur if safety measures are not taken.
SUGGESTED TOOLS: 1/2″, 9/16″, 15mm wrenches & sockets, WD-40, hacksaw, and jack stands
1. Disconnect the negative battery cable before removal of OEM exhaust. This will allow the computer to reset and recognize the new exhaust. Lay out the exhaust on the floor so it looks like the drawing and compare parts with manual.
2. To remove the stock exhaust, unbolt it at the 2-bolt flange located in front of the muffler. Disengage the welded hangers using WD-40 from the OEM rubber grommets. Do not damage stock nuts and bolts or remove the rubber grommets as you will re-use them to mount your new system. Now, cut off tailpipe and remove exhaust.
3. Install headpipe #A onto your existing stock flange and attach using stock hardware. Do not tighten. Insert welded hanger into rubber grommet.
4. Install muffler #B onto headpipe 1.5-2” with the louvers facing towards the converter. Use a jack stand to support the muffler. Use clamp #G to secure the muffler to the headpipe. Do not tighten. Muffler inlet is looking into louvers.
5. Next, remove your spare tire and spare tire heat shield. Kit will only fit with those items removed.
6. Install passenger side tailpipe #C into muffler 1.5-2”. Use clamp #H to secure pipes together. Do not tighten. Insert welded hanger into rubber grommet.
6. Install tailpipe #D into muffler 1.5-2” and secure with clamp #H. Do not tighten. Insert welded hanger into rubber grommet.
7. Install rear tailpipe hanger #I. Remove hitch bolt as seen in picture. Insert rubber grommet on hanger.
8. Install exit pipe #E onto the tailpipe 1.5-2” and secure with clamp #H. Do not tighten. Rotate pipe to best suit your vehicle. Insert welded hanger into rubber grommet. Adjust pipes to fit your vehicle with tips on so you make sure there is proper clearance.
9. Install stainless steel tip. Clamp down. When you have everything in place, firmly tighten all bolts and clamps down securely. Use stainless steel cleaner and a Scotch Brite pad weekly to prevent tip from discoloration. Inspect all fasteners after 25-50 miles of operation and re-tighten as necessary.
