face away from eachother. Then
slide two rubber isolators (G)
onto each hanger so holes align.

the factory h-pipe assembly inline
with the heat-shield screw sticking
out of the floor on the driver side

assembly and two ring clamps (I)
over the end of the axle pipes.

side and passenger side h-pipe
tubes (A) and (B) onto the fac­tory cat assembly and new axle
pipes. Install the supplied band
clamp (K) over the balance tubes
in the center of the H-pipe.

to the ground, and tight to the
converter assembly. Tighten
securely.

new JBA tips clean.
