This listing is for our Simply Performance complete XJS V12 exhaust system. This system is one of our signature products. Its made to be all OE compatible. Although this is all available separately on our ebay site this is discounted as a complete system.
We have listed some more information below. If you need to discuss your requirements please ask. To confirm, the system listed is for a complete V12 system without centre boxes. If you require centre boxes please ask, these are additional cost.
We generally keep these all in stock. If you need this quickly please get in touch to ensure we have it in stock to deliver in time.
This system is designed to OE fit 1975 - 1992. For pre 1980 cars you will need to change the over axle mounts in your cage. For anything after 1992 please get in-touch so we can discuss. As this is OE compatible the part numbers for each piece are listed below.
The exhausts we produce are hand made here in the UK in 304 grade material. Our system is made to the patterns of the OE non catalyst system so you can take all of our parts and they can be fitted within an original system non-cat. The system is a free flowing system. All the joints and bends are made to be the least restrictive as possible. They use standard Jaguar fittings and if you buy the whole system it comes with all the joints and bolts as a kit. We use a centre box replacement pipes to replace the restrictive centre boxes that Jaguar installed on the V12. The rear boxes are a light performance version along with an original style tip that is made as an oversize style 2 1/4" OD which give the car a nice deep tone on idle, upon acceleration you get a rasp from the V12. The system is very clearly a V12 sound not like many that sound like a V8 or something american. The system does introduce more noise inside but you can have a conversation in the car at most speeds. If it is too noisy or a concern we can supply centre boxes at extra cost.
As we did not get cats until 1992 here in the UK we do not install the lambda sensors in the downpipes as standard, We do have downpipes with the lambda boss/ bung pre welded, if you have cats then this may be something that would be good for you. Please remember, this system is a de-cat, you will have to check your local law whether that is OK or not.
We offer a complete kit which also includes the fitting kit but all parts can be bought individually.
