Step 1: (Carefully read all instructions before

installation) To remove the OEM system, unbolt

the tailpipe and muffler at the mating

connections, disengage the welded hangers from

the OEM rubber isolators and remove the

assemblies. Do not damage the rubber isolators

or fasteners, as they will be reused to mount the

new system.

Step 2: Install the new muffler assembly by

fitting the welded hangers into the OEM rubber

isolators and fastening the inlet of the Resonator

Assembly to the catalytic converter extension

using the OEM fasteners. Leave all clamps and

fasteners loose for final adjustments of the

complete system. Install the Y-Pipe and Muffler

Assemblies in the same fashion using the

supplied 2.50"/2.25" clamps.

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 clamps

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.
