Step 1: (Carefully read all instructions before

installation) To remove the OEM muffler on the

short bed applicaton, cut the inlet pipe 7.25" in

front of the muffler, and also 7.25" behind the

muffler. To remove the OEM muffler on the long

bed vehicle, cut the inlet pipe 10.5" in front of the

muffler, and 7.25" behind the muffler. Once the

new Muffler Delete Pipe is partially installed, use

the specific extention pipe so you can mark and

trim the OEM tailpipe to fit the outlet of the

Muffler Delete Pipe.

Step 2: Deburr the cut pipes, then install the new

Muffler Delete Pipe and extention pipe using the

supplied 3.50" clamps and by fitting the welded

hangers into the rubber insulators. You can now

install the clamp-on tip on the OEM tailpipe using

the supplied clamp.

Step 3: With all components mounted loosely,

adjust the system for overall aesthetics and

clearance of frame & bodywork. (MAGNAFLOW

recommends at least 1/2" of clearance between

the exhaust system and any body panels to

prevent heat-related body damage or fire.)

Step 4: Once a final position has been chosen

for the new system, evenly tighten all fasteners

from front to rear. The supplied band clamp must

be VERY tight to properly align the pipes and

prevent leaks (Approximately 40ft-lbs). U-bolt

clamps should be tightened to approximately

30-35ft-lbs. Inspect all fasteners after 25-50 miles

of operation and retighten if necessary.
