90-110 & Defender Sport Stainless Steel Exhaust Systems - V8
Available for all 90*, 110 & 130 V8 models up to chassis no WA159806 (including efi and large-capacity engine transplants), our stainless steel Sports Exhausts comprise tubular manifolds with large-bore single pipe systems and sports silencers. Designed to increase power & torque, Sports Systems enhance the look of your Land Rover as well.
The sound is pure V8, but comfortably refined inside the vehicle at cruising speeds.
Each system includes fitting instructions, gaskets and fittings to assemble the system utilising existing mounting positions.
Also available: manifold fitting kit and Thermo-tec manifold wrap. See panels.
*Please note, the sports system for 90 models is not suitable for the 50th Anniversary Defender V8.
HOW TO IDENTIFY MILD OR STAINLESS STEEL EXHAUSTS USING THE PRICE GUIDE
If you require a FULL standard system, then the part number in the Price Guide will have an MS (Mild Steel) or SS (Stainless Steel) suffix. If you require a PART SYSTEM or just a component, please refer to the sections on the following pages.
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 Sport 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 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 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 Electrical Section).
