vehicles.
Catalysts
are normally quite durable, so it is unlikely that
you need to replace the full system including
catalysts. An MOT emissions failure or a rattle
(usually noticeable when hot at tickover - in 'D' or
on take-up_ will usually indicate the need to
replace the catalysts and perhaps the full system.

NOTE:
Catalyst equipped vehicles (1992/3 on).
Our
sports system could be used to replace the catalyst
exhaust system on UK cars registered prior to August
1995 (subject to any change of legislation, please
enquire.)
Current
MOT emissions limits could allow not cat equipped
vehicles to pass an MOT (providing the engine is set
up and tuned correctly) up to this registration
date. Please specify when ordering as manifolds with
lamda sensor holes will be required. (Our system
part number carries a 'WS' suffix).
Sports
Exhaust
Available for all Classic V8
models, our stainless steel Sports Exhausts
comprise tubular manifolds and large bore,
single pipe systems with sport silencers.
Designed to increase power and torque,
Sports Systems improve the look of your
Range Rover as well. The sound is pure V8
but comfortably refined inside the car at
cruising speeds. Each system includes
fitting instructions, gaskets special
mountings and fittings to assemble system
utilising existing mountings where
applicable. |
Enhancements
for Sports Exhaust
Our Sports Exhaust Systems
are designed to give an increase in power
& torque on an otherwise unmodified
vehicle. The way they achieve this is by
helping the engine to 'breathe out' more
efficiently. Naturally, they work just as
well (or even better) on modified engines,
since most modifications are designed to
make the engine breathe more efficiently.
Fitting K & N air filters at the same
time as our Sports System will help the
engine to 'breathe in' more efficiently - by
removing the restrictive standard air filter
- yielding even better results. (For K &
N filters, see our Fuel Section). To gain
maximum benefit from our Sports System,
particularly in large capacity V8s (3.9, 4.2
or even 4.6 litre versions), fit our Big
Valve Performance cylinder heads. These
heads are ported and gas-flowed to help the
engine achieve optimum efficiency. (For
Performance cylinder heads, refer to our V8
Engine Section). Finally, don't forget your
fuel system: all this extra efficiency will
be lost if your carbs are worn out or your
injection system is not up to scratch! The
original carbs should be adequate for an
otherwise unmodified 3.5 engine fitted with
a Sports System and K & N filters
(provided they are correctly set up). For
the same vehicle fitted with modified
cylinder heads or a bigger engine, however,
we would recommend fitting either a Holley
or Weber 4 barrel carb (see our Fuel
Section). Similarly, standard efi vehicles
will need no modifications to the injection
system when fitting a Sports System and K
& N. If further modifications are being
considered, such as a change of camshaft,
Performance cylinder heads or a bigger
engine, we strongly recommend a remapped ecu
to provide the correct fuelling. We can
remap your existing ecu to suit your
engine's requirements exactly, giving
crisper throttle response, more power and
torque and better fuel efficiency. (see our
Fuel Section). |
Manifold
Insulation Wrap
Tubular manifolds by design
produce a vast of amount of heat in the
engine compartment. This increases the
possibility of electrical/ignition
components not working effectively and
promotes a higher risk of fire (if any
combustible material comes in to contact
with the manifold), not to mention the
likelihood of severe burns when working on
the engine! By wrapping your tubular
manifold with Thermo-Tec insulating wrap you
can overcome all these risk factors.
Thermo-Tec keeps the heat within the exhaust
manifold so the exhaust gases have a much
higher velocity, this induces negative
pressure (scavenging) which increases air
intake flow, resulting in better performance
& economy.
Technical Notes: Thermo-Tec heat wrap
- which is race & rally proven - comes
in rolls 2" wide x 50ft long and moulds
to the contours of the manifold. Being a
Silica based fabric (it does not contain
asbestos or carcinogens) it is unaffected by
oil or water, withstands temperatures up to
1000 degrees Celsius and reduces under
bonnet temperatures by up to 70%.
Snap-Strap Retaining Kit. We strongly
recommend that you use Snap-Straps to retain
the insulation wrap. These are Stainless
Steel straps with a narrow profile (for
tight spots) that you cut to length and
fasten with 'snap' type heads. |
