The ‘Spitfire’ Stage 1 kit (without air filter cover, for customers who already have a performance air filter system fitted) maximises air flow to give significant power increase.

Product Description

The ‘Spitfire’ Stage 1 kit (without air filter cover) maximises air flow to give a significant power increase. This variant of the Stage 1 kit is sold without the air filter cover, for customers who already have a performance air filter system fitted.


The stainless steel exhausts, utilising free flowing straight-through absorption chambers, maintain the look of the original parts with a subtle design twist.  The resulting sound is deeper and more mellow than the standard exhaust.


Garage 56 has addressed the issue of cracking exhaust systems: uniquely the Garage 56 exhaust features a flexible joint just ahead of the silencer body.  This vastly improves the isolation of the silencer from the vibration of the engine.


The kit comes complete with new stainless steel mounting brackets and fasteners.

Is the Stage 1 Kit compatible with 2014 models
In short, YES. The 2014 edition addressed issues with the chassis, overheating and suspension, but not the engine.


Does the stage 1 kit require upgrading the brakes
We have found the factory fitted brakes to be adequate. However, with the engine producing more power and revving more freely, you may well find yourself driving faster than you used to. Be alert to signs such as brake fade.


Do we fit the Stage 1 Kits?
Garage 56 kits are available direct from Williams Automobiles, who can fit them to your car. Of course, they are available directly from us, for you arrange fitment yourself: the job of fitment can be done by any reasonably competent “home mechanic”.
If ordering from our website, there is the option of a delivery address different to your billing address, useful if you want to have the Stage 1 kit delivered directly to a garage or workshop.

You will need to use your existing hexagonal base AV (anti-vibration) mounts. If your car is fitted with the old specification round section AV mounts, we recommend you acquire a set of the later specification AV’s from your Morgan parts supplier.
