Porsche 930 Stainless Steel Exhaust Installation

Step 1. Remove 8mm nuts from behind bumper where black rubber
bellows attaches to bumper. Also
remove 8mm nut from rubber trim on bumper. Do this on both sides
of car.

Step 2. Remove black rubber trim using 2pt Philips
screwdriver. Notice separation of bellows from bumper
on right picture. You may need to remove two screws holding
fender lower section to give a little
flex (refer to picture in step 5 - be careful). Also notice two
nuts holding bumper to body (actually to
hydraulic dampers). These will be removed during step 4.

Step 3. Remove two Philips screws holding license plate lamp
and detach lamp housing. Pull wires out
from behind bumper.

Step 4. Remove the four (two on each side) nuts holding bumper
to the body (picture in step 2). With the
help of another person (highly recommended), gently work the
bellows off the bumper and remove the bumper.

Step 5. Remove pipe connecting check valve to catalytic
converter. The two small circles show the bolts
holding the lower fender section referred to in step 2. Leave
check valve on car.


Step 6. Soak four nuts that connect catalytic converter to
turbo with penetrating oil. Since I was replacing
the exhaust, I cut two bolts that connected the catalytic
converter to the muffler. This allows more room to
get to the nuts on the turbo. Remove the muffler straps and allow
the muffler to hang off the catalytic
converter. You can remove the third bolt, if you can get to it,
to completely remove the muffler.

Step 7. Remove four bolts holding catalytic converter to
turbo. If you should remove a stud from the turbo,
replace it with a new one. Be sure to clean all remaining studs
with penetrating oil and a thread cleaning kit
(tap and die set will do - you will need M10X1.5). Replace 4 nuts
with new nuts.

Step 8. I had to modify my bracket to fit the new stainless
steel exhaust. This took a big vise, a 4 LB hammer,
and a couple of pipe wrenches (also a little blood, sweat, and
tears). I also cut off the inner strap flange and
only used the outer flange with the provided stainless strap.
When you are satisfied with the modified
bracket, attach the stainless steel exhaust using the four new
nuts to the turbo (don't forget new flange gasket)
and attach the exhaust to bracket using the stainless steel
strap. Since I installed a GHL (and I think B&B
are the same), I had room to get to the turbo nuts to tighten
them down because the tail pipes are
removable (and adjustable). Attach tail pipe using supplied
stainless steel strap (do not fully tighten).

Step 9. Re-attach the bumper using steps 1-4 in reverse order.
Adjust tail pipe and tighten stainless steel
strap.
