THE BRIEF

We commissioned Scorpion Exhausts Ltd to design and manufacture a custom specification exhaust system, based largely on the highly successful Pugsport, to fit the Citroen Saxo VTR & VTS models.

The specification was to be a lightweight, very high quality stainless steel system, that produces more power and torque than the standard exhaust. It had to be silenced to a suitable level for road use. It has to give proven performance gains and the design of it has to suit the car's image. It needs to be easy to fit and not require any modification to the standard car.

Design of the system began with us supplying Scorpion with a standard specification Saxo VTR (phase 2) test car to build the exhaust on site at their factory in Derbyshire, UK.

A critical stage of the development was to subject the prototype components to a series of tests on the dyno (rolling road) to check the actual performance. Firstly, the standard VTR with the standard exhaust system was tested to give us some base power/torque figures to compare to. The car was then fitted with the Scorpion prototype system and we did some extensive back to back power runs.

In addition to the dyno runs we also subjected the car to "on the road" tests to see how the system performed whilst driving, and tested both the 'Road' and 'Race' tail pipe versions.

THE RESULTS

The dyno testing was a huge success. The prototype system was consistently producing 111bhp (peaking at 111.6bhp) showing a good increase in power and torque over the standard system (which produced 106bhp on the same dyno). On the road tests backed up the dyno results and the increased power was noticeable in daily driving, matched with a purposeful but not chavvy exhaust note.

Once we were happy with the final design our test car was subjected to 6 weeks of extensive road use. This was to ensure the exhaust performed in a variety of different environments and conditions that would occur on a daily basis. It was also to test the fitment of the system to make sure there were no problems in the design. The road testing was a huge success and the prototype system performed faultlessly. The noise level was spot on, and you could feel the the extra power and grunt on full throttle.

VTS RESULTS

Standard exhaust: 118bhp

Saxsport 3” Road System: 123.2bhp

The Saxsport exhaust tested was brand new and box fresh, and usually exhausts produce slightly more power after some more bedding in, running time and coking up. The Pugsport system has shown proven power gains of up to 7bhp on a Peugeot 106 GTi, so we see no reason why the Saxsport would not give similar results on a Citroen Saxo VTS

REDUCED WEIGHT!

The weight of the standard exhaust system on a VTS is around 15.8kgs (cat = 3.7kgs, centre = 4.6kgs, back box = 7.5kgs) compared to the weight of the Saxsport being 9.1kgs (centre pipe = 3.4kgs, back box = 5.7kgs). A weight saving of 6.7kgs, which isn't to be sniffed at really, as weight loss equals performance gain. If you take the weight of a VTS as 898kgs and having 120bhp, that gives 133.6bhp per tonne. With a weight loss of 7kgs thanks to the Saxsport, the weight goes down to 891 which produces a higher power to weight ratio of 134.6bhp per tonne…in racing every little counts!

CENTRE PIPE OPTIONS

The Saxsport centre has been designed with a dummy cat silencer identical to the Pugsport system. This does not currently have a position for the lambda sensor to fit.

Later Saxo VTS's which have three-plug ECUs and L4 emissions control use two lambda sensors and have an EGR pump fitted, part of which is bolted to the front of the head. These are usually 2001 onwards, so beginning from Y-platers. On these models, you need to cater for the second lambda sensor that fits into the standard exhaust. There are three different options for these models when fitting a Saxsport:

> Use a lambda sleeve

> Fit the Saxsport motorsport cat pipe which has lambda positions

If you fit a lambda sensor to the decat centre pipe, there is a possibility of the engine management light coming on, due to the second lambda detecting “dirty” air straight from the engine, rather than passing through a working catalytic converter first. If you fit the cat pipe or use a lambda sleeve, then the warning light should not appear on the dash. Please note that the cat pipe should pass an MOT but the decat centre pipe will not.

DECAT INFORMATION

This has a dummy cat silencer so will not pass an MOT on models which have a cat pipe after the downpipe (early VTR/VTS models). On later model VTR's which have a cat in the manifold, the Saxsport will still fit fine but will not replace the manny cat so will not be a complete decat system unless you remove the manifold cat. Advantage of keeping the manny cat is it should pass an MOT.

A BRIEF FITTING GUIDE FOR THE SAXSPORT EXHAUST

Each Saxsport exhaust is supplied with a fitting kit (shown below) that includes all you need to fit the exhaust. Below is a quick guide that gives you some useful tips and advice. If in any doubt at all please consult a professional mechanic.

Raise car and secure with axle stands to enable access to exhaust system.
Remove complete standard exhaust system by undoing the 10mm nuts at the downpipe to centre section joint, removing the bolts and unhooking the three rubbers along the exhaust.
Check that the exhaust joints of the Saxsport are free from debris. Clean as appropriate.
Fit back box to rear rubbers on hangers first as it’ll be more difficult to manoeuvre once the centre section is in place. Standard specification rubber mounts are supplied in the fitting kit but you can use stiffer uprated mounts if required from the likes of Powerflex.
Apply exhaust fitting paste (e.g. Firegum) to the slip joint at the rear part of the centre section.
Slide centre pipe fully into the back box pipe and fit rubber hanger to the centre section.
The Saxsport centre pipe is supplied with a small round metal sleeve that simply slides onto the front of the centre pipe. This is supplied because there are 2 different sizes of downpipe fitted to the Saxo depending on model. Please fit this sleeve if required.
Fit new fire ring to the front of the centre section. Exhaust paste is optional for this flexible joint.
Loosely bolt centre section to downpipe, noting the correct orientations of the bolt, collar, washer, spring, cap and nut.
Check orientation of the tailpipe in the bumper cut-out. Adjust rubbers and rotate back box and centre section as necessary.
Secure centre section to back box slip joint using exhaust clamp supplied or alternative.
Secure front of centre section, ensuring that here is still travel left in the springs to allow for engine movement.
Start the car, idle for several minutes and check for leaks in the exhaust system.
Remove axle stands, lower car back to the ground and enjoy the distinctive sound of the Saxsport!
