Instructions
1
Raise vehicle and support exhaust system.
2
Loosen the two 13mm nuts on the exhaust clamp
between the front muffler/downpipe assembly and
the center section of the exhaust.
For systems with double sided mufflers, loosen
both clamps.

3
Remove the 13mm bolt holding the front exhaust
hanger on the rear muffler.
4
Remove the 13mm nut holding the rear hanger on
the rear muffler.
For systems with double sided mufflers, remove
the 13mm nut on both sides.
5

6
Pry off the rubber exhaust hanger on the driver’s
side for the middle muffler.
7
Gently lower the exhaust system. Slide rear
muffler(s) off of the front muffler/downpipe
assembly and remove from vehicle.
8
Remove the rear exhaust hanger from the stock
exhaust. Note orientation. This will be reused on
the driver’s side muffler of the STaSIS exhaust
system.
For systems with double sided mufflers, reuse
hangers from both mufflers.

9
Remove the 3 13mm nuts holding the front
muffler/downpipe assembly to the flex joint.
10
Gently lower and remove the front
muffler/downpipe assembly from the vehicle.
11
For vehicles with a single exhaust outlet valence,
gently pull valence from the corner towards the
center to remove.
For vehicles that already have a dual outlet
valence, skip to step 17.

12
Using a 10mm socket, remove the 3 plastic nuts
holding the passenger side cavity cover.
13
Remove the push clip retainer in the rear right
corner of the cavity cover. Remove the cover from
the vehicle.
14
Install the supplied exhaust hanger onto the
passenger side muffler of the STaSIS exhaust
system. Use the pictured speed nuts in the next
step.

15
Install the supplied heat shield for the right side of
the vehicle using the supplied speed nuts.
16
Make sure there is adequate clearance between
the heat shield and the sway bar. The heat shield
should be tight against the chassis. If not, gently
bend the heat shield.
17
Install the downpipe using the supplied hardware
and gasket.

18
Support the downpipe during installation of the
center section of the exhaust to minimize stress on
the flex joint.
19
Install the center section using the supplied
hardware and gasket.

20
Install the driver’s side muffler. Attach the exhaust
hanger previously removed from the stock exhaust
onto the left muffler. Slide one of the supplied
exhaust clamps on before installation. Orient the
clamp nut to be outboard. Tighten the clamp just
enough so you can still adjust the pipe.
(Apply anti seize to all assembly bolts to allow
for ease of removal)
21
Install the short intermediate pipe with exhaust
clamp onto the center section. Orient the clamp
nut outboard. Install the supplied exhaust hanger
on the right side muffler. Install the muffler and
exhaust clamp with the clamp nut oriented towards
the front of the vehicle. Tighten the clamps just
enough so you can still adjust the pipes.

22
Install the rear valence appropriate for your vehicle
with twin tips. Start on the outer edges and work
your way inward ensuring the mounting tabs are
firmly seated in the bumper cover.
23
Adjust the mufflers and pipes in order to gain equal
clearance and depth in the exhaust openings. The
STaSIS logo should be partly covered when the
exhaust is cold. The system will expand when hot
showing the full logo.
24
Once the adjustment is complete, tighten all the
clamps and install the bridge support bar between
the left muffler and the intermediate pipe. If the
two tabs do not line up, the adjustment is incorrect.
Support bar can be in tension to properly space the
muffler width in the valence.
During and after install, wipe off all assembly
and shipping particles from the exhaust. If
dust is not wiped off, once the exhaust gets
hot, the particles will burn onto the stainless
steel finish and become permanent.
Ensure the exhaust tips on both sides protrude
from the bumper evenly and are not touching
any body panels. Clearance to all body panels
should account for thermal expansion of the
exhaust, up to ½ inch in length.
25
Test drive to ensure there are no abnormal noises.
Minor smoke and aromas are normal with a new
exhaust system. These will fade rapidly under
normal driving.
