SECTION 22 - EXHAUST INSTALATION
Parts Required:-
- Complete Exhaust System ( Comprising- Manifold, Long silencer, Short silencer, Intermediate
Pipe, Three band clamps, two silencer-clamping straps and a retaining strap.)
- 8 x exhaust studs and 8 x M8 Binx nuts (supplied in kit)
Step 1 Fitting Manifold
As previously mentioned the exhaust manifold is easier to fit before the engine is fitted into the
chassis. So when the top engine frame is fitted then you can fit the manifold. First fit the 8 x M8
studs supplied with your kit into the cylinder head. Tighten these studs using two M8 nuts locked
together onto each stud. Check before fitting the manifold that you have an Exhaust gasket in
each port, if you have not or wish to change them for new ones you can purchase these from
Westfield. Then locate all the clamping rings onto the studs and bolt up with the M8 Binx nuts
supplied.
8 x M8 Manifold Studs
8 x M8 Binx Nuts
4 x Clamping rings
Note; The Remainder of this Section can only be completed when the Bodywork is
Finally fitted.
Step 2: Main Cat Silencer and Pipe
If you are fitting a Rear Wing you need to fit the two Wing posts and cross stays before you can fit
this section of the exhaust because it goes through the middle of the posts. If you are putting your
XTR2 through an SVA test then you cannot submit it with the wing or post fitted, so just fit the
exhaust as now described.
The round end of the silencer has the Catalytic converter fitted and should go onto the manifold
with a band clamp as shown, with the oval end (widest section parallel to the ground) running
over the Differential area. Here will fit the mounting bracket with a long flat mounting strap that
can be riveted or rivnuted to the chassis. This would be best done when the whole system is in
position.
