Type of Part: Genuine/ OEM, Performance
Model of Jaguar: XJS pre facelift 1975-1991, XJS facelift 1991-1996
Compatibility: AJ16 XJS from (V)194775, Will fit XJS AJ6 3.6 and 4.0 with correct manifold and rear boxes
Made in: England
Material: Stainless Steel
Features: Supplied with tubular manifold and centre boxes

This listing is for a full XJS 4.0 AJ16 stainless steel exhaust system with tubular manifolds and centre boxes. This is the later generation of exhaust system that is OE compatible with all AJ16 4.0 XJS's after 1993.5 (V) 194775. This system will fit earlier 4.0 AJ6 and 3.6 XJS cars if installed complete, we would need to change the manifold plate and swap to earlier rear boxes. Please let us know at the time of purchase.

The specification of this system is modeled on the 4.0 AJ16 1993.5-1996. This system is very different to the earlier AJ6 4.0 & 3.6 XJS system. It is larger diameter and looses the restrictive olive joints. 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 as you are buying the whole system it comes with all the joints, clamps and bolts as a kit. 

This is our tubular manifold boxed system which is our signature top spec system. Although it is a boxed system it will be a bit louder then standard system due to the tubular manifold and it being stainless steel rather then mild steel . If you are looking for a louder version of this system we can supply this system without centre boxes so its straight through to the rear box.

The rear boxes for the XJS from 1993.5 are different for earlier cars as the exit has a small S bend on it to drop the tip down below the exit on the bumper. If you want to fit this onto a car before the big bumpers upto (V) 188104 then we can supply it with the earlier rear boxes.


All UK and EU spec XJS AJ16 cars had catalysts as standard. In the UK its a legal requirement to run a catalysts. Our systems do not have catalysts but being OE sized you are able to swap in your catalysts if required (slip/slide joint fitting only). High flow HJS catalysts can be supplied but at a significant increase in cost. Our downpipes come with the lambda boss/ bung pre welded for you to run your 02 sensors. Our systems dont have facilities for upper heat sensors or EGR. These must be deletes and mapped out. 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 and are listed on this website under their part numbers. This is much more expensive as this full system is discounted as a system price
