FAQ

What is 441 grade Stainless Steel?

441 is a magnetic stainless steel which is therefore classified as a Ferritic stainless steel. People sometimes create a perception that magnetic stainless steel is of poor quality.  This is false and used in the right application magnetic steel may even perform better than non-magnetic stainless steel.

How does 441 hold up with our harsh Australian conditions?

The properties of 441 tube make it hard to beat. 441 grade stainless steel outperforms 409 stainless steel in both oxidation, corrosion resistance and high temperature strength. As in other types of stainless steels, it is the content of chromium that imparts corrosion resistance to the alloy. Our competitors use 409 grade stainless steel material which has a chromium content no more than 11.75%. Our premium 441 grade stainless steel material has a minimum of 18% chromium.441 grade stainless steel tolerates all heat and stress cracks due to the Niobium and Titanium content. These elements in the material help formability and heat dispersion.

DOES SIZE MATTER?

why we choose 2 3/4'' OVER 3''

This is the most frequently asked question we get!

Exhaust systems are fitted to remove hot, noxious exhaust gases from your engine, reduce engine noise and reduce exhaust emissions. Most argue that the key to this improvement is to reduce exhaust back pressure, usually achieved by using larger-diameter tubing and free-flow mufflers. However, what’s actually required is to minimize the resistance to gas flow in order to keep the exhaust gas flowing as quickly as possible so that the burnt gases are efficiently extracted from the engine. This means that the saying ‘bigger is better’ is not always the case. In fact, the optimum diameter of the exhaust tubing varies according to the amount of exhaust gas being produced, which depends upon engine RPM and load. Smaller turbo diesel motors (2L-3.5L) don't require such large diameter exhausts. We have done vigorous testing on the smaller motors to get the best performance possible. With this research, we have used various sizes of tube and in most cases 2 3/4" comes out on top.

DPF DELETE PIPE?

We do not manufacture or supply any DPF delete pipes. As per the Australian and Emissions Standards, there are large fines for the owner of the vehicle and the company removing the DPF in any instance. If the car was manufactured with a DPF, it must remain on the vehicle to be roadworthy on all Australian roads. Removal will void any warranty claims with the manufacturer or any insurance claims.

DO BEAUDESERT EXHAUST SYSTEMS INCLUDE THE DUMP PIPE?

Yes, any of the systems for turbo diesel vehicles will come straight off the back of the turbo and therefore include the dump pipe (excluding vehicles fitted with diesel particulate filters (DPF)).  We also include a provision (1/4″ gas BSP) to fit an EGT gauge on all of our dump pipes. These all come standard with ceramic coating.

DO BEAUDESERT EXHAUST SYSTEMS INCLUDE A MUFFLER?

Yes, you will receive a perforated straight-through muffler that keeps noise levels to a minimum, and allows maximum flow through the system. Depending on the vehicle, your system may also include a resonator to further reduce noise levels.

CAN BEAUDESERT EXHAUST MAKE A SYSTEM FOR ANY TYPE OF VEHICLE?

We manufacture systems for most types of 4WDs. If your car isn't on our website and you can get it to our workshop please contact our office (07) 55412767 or send us an email [email protected] to find out if we can do yours!

WHAT KIND OF INCREASES CAN I EXPECT BY FITTING A BEAUDESERT EXHAUST SYSTEM?

Average customer feedback indicates you can experience a power increase of approximately 10-12% and an increase in fuel economy by up to 8-10 %. Vehicles fitted with a DPF range from approximately 5-6% increase in both power and fuel economy. These results will vary depending on how the vehicle is driven, what it is being used for and various aftermarket accessories.

WILL A CUSTOM OR AFTER-MARKET SYSTEM BE ANY LOUDER THEN THE STANDARD?

In short – No.
We use one or two mufflers on turbo diesels (depending on the vehicle) to ensure quietness. We mostly use a perforated straight-through muffler, which absorbs noise levels and cuts out any droning inside the cabin. On the petrol & non-turbo diesel vehicles we use two mufflers (again perforated and straight-through) and also a rear resonator just to cut out any excess noise and drone that these types of vehicles tend to emit.

AM I ABLE TO ORDER MY SYSTEM WITHOUT A MUFFLER?

Yes you can. It is your choice as to what you want supplied. Systems come standard with a muffler or resonator depending on the system. We are able to replace the muffler section with a resonator if you wish for the system to have a deeper note. We can also supply a no muffler pipe, this is up to the customers discretion as we do recommend this for off road use only.

DO YOU FIT PERFORMANCE MODULES?

Yes! We supply and fit STEINBAUER modules! These modules work hand in hand with our exhaust systems to provide ultimate power and fuel economy.

HOW LONG WILL IT TAKE TO FIT THE SYSTEM?

The time it takes to fit the system will depend on the vehicle and how old it is. The hardest part is getting the old system off which can be fairly time consuming if nuts and bolts haven’t been undone in more than a decade! Generally these systems take approximately 4-5 hours to fit if there are no complications.

HOW LONG UNTIL I RECEIVE MY SYSTEM FROM TIME OF ORDERING?

If your system is in stock, we can generally despatch it the same day. If not, lead-time is approximately 5-7 working days for 441 Stainless Steel and 7-10 working days for 304 Stainless Steel. After your system has left our dispatch, delivery time will depend on your location.

WILL FITTED ACCESSORIES SUCH AS LONG-RANGE FUEL TANKS, SIDE STEPS OR GAS TANKS ETC. AFFECT INSTALLING A SYSTEM?

Our exhaust systems follow the same route as the original system and are made to suit standard, unmodified vehicles. Generally if your accessories (long range fuel tanks, extra water tanks, toolboxes, spare tyres, side steps, rear bars etc.) interfere with the original system then they will interfere with one of our systems. We manufacture alternative parts to suit some aftermarket accessories, however in some cases to overcome this problem the system may have to be fitted in our workshop so we can customise the route of the new system in this case additional labour & materials charges will apply.

WHERE CAN I HAVE MY EXHAUST SYSTEM INSTALLED?

We have our very own workshop located at

158 Enterprise Drive, Beaudesert, Queensland 4285, Australia.

HOW MUCH NOTICE SHOULD I GIVE TO MAKE AN IN-HOUSE BOOKING?

We prefer 5-10 days notice to make sure all parts for the system are manufactured before your arrival. If the system is in stock, and depending on how many other vehicles are booked for fitting that day, we may be able to fit you in straight away. Please contact our office to make a booking or send us an email to see which days we have available.

WILL THERE BE ANY FITTING INSTRUCTIONS IF I WANT TO FIT THE SYSTEM MYSELF?

We supply you with basic fitting instructions for all of our exhaust systems. When you order the system your sales consultant will advise you of the difficulty rating on fitting your chosen system. If you have any trouble with fitting the system please don’t hesitate to contact our office and speak to one of our experienced exhaust fitters.

WHAT IS THE WARRANTY ON A BEAUDESERT EXHAUST SYSTEM?
