Removal of Stock System:
Filter-back exhaust:
1. Apply some penetrating lubricant liberally to all exhaust fasteners,
hangers and rubber insulators.
2. Loosen the nut on the band clamp located behind the particulate
filter using a 15mm wrench or socket. Refer to Figure 1.
3. Cut the exhaust as shown in Figure 2. Remove the muffler and tail
pipe from the OEM rubber insulators. Remove from the vehicle.
Down pipe:
4. Remove the heat shield from the turbo by removing the five 8mm
head bolts. This shield cannot be fully removed but sliding it out of
the way will allow access to the V band Clamp at the turbo outlet.
See Figure 3.
5. Loosen the OEM V-band Clamp at the turbo outlet. Once loose, the
clamp bolt can be released from the clamp. There is a retaining tab
located at the 12 o’clock position on the OEM down pipe that must be
pried off the turbo flange to allow the pipe assembly to be removed.
Refer to Figure 4.
6. Remove the 2 OEM bolts from the ball flange at the outlet of the
down pipe. Keep these bolts, they will be reused. Use a pry-bar to
shift the particulate filter rearward to allow the OEM down pipe to
drop down a few inches.
7. The OEM down pipe must be cut in order to remove it. Use a
sawsall with a long enough blade to cut through the pipe. Note the
location of the cut. Refer to Figure 5.
8. Remove the lower section of the OEM down pipe. The upper
section of the down pipe can now be removed by working the down
pipe down while rotating it clockwise approx 90 degrees as viewed
from below. This will take some work, as it is a very tight fit.
