ATTACHMENT OF THE PIPE UNDER THE BODY
The attachment of the pipe under the body is by
the rubber mounting at (1).
This can generally be unhooked by hand by ta-
king the weight off the exhaust pipe.
However, in certain cases, it may be necessary to
slacken the bolts retaining the support ( 2) under
the body in order to more easily unhook the rub-
ber mountings. During operation, the catalytic converter reaches
high temperatures, and consequently, it is vital
not to park the vehicle in a place where combusti-
ble materials could come into contact with it, and,
as a result, ignite.
Under certain conditions, these materials could
ignite.
IMPORTANT:
- the seal, between the exhaust manifold gas-
ket face and the catalytic converter (inclu-
sive), must be in perfect condition,
_ it is imperative that every gasket removed be

REPLACED (especially at the catalytic converter
flange)
- during removal and refitting, the catalytic
converter must not undergo repeated mecha-
nical shocks, as it will be damaged.
CUTTING THE EXHAUST PIPE
The exhaust pipes are of the monoblock type.
There is no join from the beginning of the cataly-
tic converter or the expansion box, to the end of
the silencer.
It will therefore be necessary, when replacing one
of the components in After Sales, to cut the
exhaust pipe.
For this, it is absolutely essential to accurately :
- mark the area to be cut,
- use the cutting tool Mot. 1199-01,
- fit the after sales sleeve .

MARKING THE AREA TO BE CUT
The area to be cut is defined by two punch marks
on the exhaust pipe.
99226-1R
Depending on engine, there are a maximum of
two cutting areas on the exhaust pipe, situated
between the catalytic converter and the
expansion box and between the expansion box
and the silencer.
The distance between the two markings is 90 mm.
To cut the tube, mark the central point (D) bet-
ween the two markings (P
1 and P2).

IMPORTANT: to cut the exhaust pipe, it is essen-
tial to use tool Mot. 1199-01; this tool allows
2mm thick pipes to be cut.
