QuickSilver Exhaust Systems for the SL500 and SL550 from GMP

Since 1973, the QuickSilver have provided exhaust for the World’s Finest Cars. a range that encompasses prestige and exotic SportscCars, produce superior exhaust to increase performance durability, appearance, enhance sound and weight, saving up to 40 kgs against an OE

GMP Performance is proud to be include line up for Mercedes among the to offer you. Our customers a high standard and nothing of excellence is what we aim to offer. We QuickSilver Exhausts will not meet your expectations for SL but exceed them.

How Loud It Be?

Loudness is truly a matter of taste. We offer sound for many modern systems and our systems as Heritage, Sports, and SuperSports Plus. As a guide:

is an exact replica of the original

is for the car used every day

SuperSports is for the who enjoys his car mainly on the weekend or for fun

SuperSports Plus is for the enthusiast who to optimize the experience.

Benefits of a Steel ‘Sports’ Exhaust

All car are compelled to comply with more stringent worldwide and sound regulations and now seem to the strictest of these to all their

* We can improve on the materials used to longer component life.

* quality materials allow weight to benefit all areas of

For example our Lamborghini Murcielago eliminates over 30 kilos and our Exige ‘Ti’ system 8.2 kilos – both from the of the car improving balance.

If appropriate we can the exhaust to allow a worthwhile in the centre of gravity as with our 360 and Porsche GT3 SuperSports systems.

* We personalisation by providing an alternative with different tail-pipe and polished silencers.

* We can improve on the (especially on forced induction by reducing the internal restriction.

* is one of the most important sensations of a Sports Car. We provide the to choose a level of sound is appropriate to you.


Our ‘straight through’ silencers a perforated tube surrounded by a metal sock. Made semi-continuous (Type 434) steel filaments this outperforms conventional glass and alternatives at high temperature and is to insulate and retain the acoustic This is an essential component for high temperature applications.

For absorption we still employ strand Basalt filament offers excellent acoustic up to 1500 Hz. It’s thermal are comparable with continuous temperature glass but more at temperatures over 600° C. material requires rigid procedures in the factory.

So, for environmental we are moving over to use Advantex and stuffing, these have temperature and acoustic properties as the .

Advantex is manufactured by Owens Corp. Says Heinz President, Composites Systems The glass fiber remains in even under the harshest meeting manufacturer’s extended requirements. This has been at Toyota, Volvo, DaimlerChrysler and GM

In our conventional chambered silencers we various techniques to fabricate all the components. Stricter emissions are demanding ever-more complex designs and here are a couple of drawings made for us by the late Bob The first is a Ferrari F355 showing seven internal in one silencer and featuring internal of different length diameter to musical chords at different The second is another Ferrari, a with a similar layout.

Exhaust Development

After a car that we should be manufacturing a exhaust for, we review the performance, see how the manufacturer has designed the exhaust and then decide and if, we can improve it.

What combination of or advantages can we provide?

And what the customers for this model

After answering these we manufacture a prototype and obtain a car for

We often develop new systems in with a specialist in that where we can combine his experience of the with our exhaust skills.

The stage is to quantify the improvements by the sound volumes, weights and gains.

Is the fitting process Are the expected benefits present? Is the sensible? Is the appearance correct? Is the quality right?

Sometimes process must be repeated but when the answer to these is the newest QuickSilver ‘Sports’ can proceed to production.


We employ various techniques for manipulation, most commonly:

Our volume systems are mandrel on our Addison DB76 Databend This CNC machine pulls the around formers whilst a of articulated ***** (the are simultaneously pulled through the to maintain it’s section and the highest quality bends.

Our or low-volume ‘classic’ systems are press bent on Ben Pearson machinery. The tube is first cut to the length, one end has a plug welded, it is filled with dry silver the other end is welded up and then solid tube is bent The sand fill ensures the tube maintains it’s during bending in this but laborious process.


Steel — There are 120 different alloys of stainless with various properties, mainly used for car exhausts

Type 304 austenitic is generally as the best grade for automotive use and is the alloy that we use, in and annealed form, for 98% of our exhaust because of it’s combination of formability, durability and cost. (10%) and Nickel (19%) are to the base steel. As a non-magnetic it is particularly specified for armoured It has excellent corrosion resistance.

409 is probably the most popular for original equipment exhaust and especially catalytic converter and pipes. Chromium (11%) is the addition to the base steel. corrosion resistance is not as good as 304 but the cost is lower and availability

Types 316 and 321 are similar to 304 and occasionally for automotive exhausts. They particular chemical and heat virtues.

Types 309 and 441 are two examples of specialist with particularly high to heat and stress. We were asked by a major Sports Car to employ these grades in an manifold for a special model was subject to extraordinary conditions – ‘US Federal Certification requires emission-critical components to have a of 10 years’.

Titanium — and its are relatively new engineering metals they have been in use since about 1952. is not an ‘exotic’ metal, it is the fourth abundant structural metal in the crust. It is an extremely attractive for engineers because of it’s strength to weight ratio, elevated temperature properties and corrosion resistance.

We presently use in some of our Lotus exhausts as the availability of appropriate tube and improves, we are looking forward to more applications for this

Stainless Steel and the Environment

The source of Raw Material for making steel is re-cycled metal.

re-cycling route has been for many years and the economics of the steel-making industry depend on

Worldwide, over 90% of new stainless is produced from re-cycled

The steel is melted electrically and in cases refined by using air-distilled gases, such as Great care is taken to fume and dust emissions, plants are equipped to re-cycle into the steel making

Most of the materials consumed the steel-making process, including water, lubricating oils, acids and inter-leaving paper are in the plant or by specialist contractors.

It is advantageous for stainless steel and processors to ensure their and in-process consumables are returned for Our waste materials are collected

As stainless steels are corrosion their life expectancy is long. A minimum of maintenance is and so, although more expensive they offer attractive cost benefits over such as mild steels.

are no proven health risks the normal use of stainless steels

Catalytic Converters

Most car have been fitted a catalytic converter containing a core or ‘brick’ (which it

These ceramic catalysts cores with the equivalent of 800 cells per square inch giving a flow area of 45%.

The ceramic cores over a relatively short range, can be subject to overheating and are vulnerable to impact damage due to lack of flexibility.

The modern ‘Sports’ Cat has a microscopically thin honeycomb metallic core of about) 200 cpsi to which the Platinum and Rhodium are applied at a greater density (25 grams per foot compared to 10 grams on a ceramic product). This all in a flow area of approx 85% remaining clean enough to emissions requirements.

Their efficiency allows these cats to be smaller, lighter and durability is superior. Most ‘Prestige’ cars now have cats as original equipment.

Superior Materials, more flow, less weight, size, better sound, life — through the use of and Composite materials as well as stainless alloys innovative designs to produce the result the wants.

Of particular interest at present is the of a sintered stainless tubing. is composed of compressed stainless of variable densities which the potential to offer acoustic within the tubing of an exhaust — offering the reduction and even the elimination of the silencers.

QuickSilver Exhausts

QuickSilver was in 1973, originally in Esher, At this time the average expectancy of an original equipment system was only 18 months was a demand for something better!

settled down in Battersea, London from 1985 to

In 2004 QuickSilver’s marketing and moved to new purpose -built in Wormley, Surrey, to focus on the of a modern QuickSilver range of for the world’s finest cars.
