When you hit the tracks or beaches fully loaded, it’s easy to feel like your 4WD is a bit sluggish, heavy and lethargic, with a couple of hundred kilos of gear and the whole family on board, no matter how grunty your motors specs are, there still may be much left to be desired, particularly when driving on sand and through soft muddy tracks. Have no fear, gaining a few extra ponies under the bonnet is a lot easier than what you think and by installing one or two simple upgrades you’ll be grinning all the way to the fuel bowser too!

Since the early days of engine modifications, there is one simple principle that will allow your stock standard motor to perform at its highest capability, and that is allowing it to breathe freely. Due to manufacturing cost constraints and developing vehicles for markets with insanely strict restrictions and emissions standards, manufacturers develop engine systems with bolt-on restrictions. With many modern 4WD Vehicles having the potential to unleash smoother power delivery and quicker engine response by simply upgrading these limiting components!

To help you unleash the maximum potential of your offroad vehicle, 4WD Supacentre has worked closely with Australian manufacturers and fabricators to develop a series of top quality, high-performance Domin8r Exhaust systems that are designed to be DIY installed easily underneath your 4WD.

There are many factors to why a free-flowing exhaust can unleash your vehicle’s potential we will go over below;

MATERIAL

When shopping around for an exhaust system upgrade for your vehicle you can see many different materials from raw steel to high tech coated ceramics. With this plethora of options on the table, it pays to make the right decision for you to get the best value for money. The top of the line within the Adventure Kings Range of Domin8r Exhaust systems is the 409 stainless steel exhausts, unlike marine grade 303 stainless that many people are familiar with, 409 stainless is less shiny and has ferrous properties. 409 Stainless is one of the best choices for an exhaust system as it is durable and can withstand lots of vibration, and many hot and cold cycles without getting brittle, like it’s more popular marine grade cousin may, whilst maintaining excellent corrosion resistance.

The 409 stainless exhaust requires a few specialized techniques with construction so is a fraction more expensive than the Aluminised steel option within the Domin8r Exhaust range. As a more affordable option, Aluminised steel is extremely corrosion resistant, whilst being  durable in hot environments due to it’s thin hot dipped aluminium coating, applied in a similar fashion to galvinising, with greater durability for the underbody of your vehicle.

THE BENDS

We’re not talking about diving here! The way that a pipe is bent can and will determine how easily a gas will flow through it. There are 2 main methods for bending a pipe, firstly by applying pressure using hydraulics in a similar way to how you would bend a piece of wire with your hands, this is called ‘Pressure bending’. By pressure bending a pipe you effectively ‘pinch’ the cross section of pipe at the bend, this results in a restricted gas flow through the system, and reduced performance. Many vehicle manufacturers employ this method of exhaust manufacture because it is cheaper and easier to build on a mass scale, regardless of the performance lost by this method.

The other way that a pipe can be bent is by using a ‘mandrel’, this is an insert that holds the inside walls of the pipe at a consistent diameter, whilst the pipe is pulled around a ‘die’ or a curved mold. By using mandrel bends you allow exhaust gas to maintain its flow all the way out of the system and is the preferred method of manufacture for performance exhaust systems all over the world. The whole range of Domin8r Exhaust systems utilise mandrel bent piping.

DESIGN

When designing an exhaust system for mass manufacturing, factors like ground clearance are sometimes neglected in favor of a system that uses the least amount of material to get the exhaust gas from the motor to the rear of the vehicle. Being built by 4WDers for 4WDers Domin8r Exhaust systems are designed with off road driving in mind, paying special attention to the clearance underneath a 4WD, they tuck neatly underneath your vehicles underbody, meaning you will not get caught up on obstacles on the track, they also are designed to keep your tailpipe from sticking out and getting pinched on rocky sections of track.

All Domin8r Exhaust systems fasten directly to your vehicles turbo dump pipe, employing heavy duty 4 bolt flanges, and includes all fasteners and gaskets. The 3” dump pipe back systems all include high flow catalytic converters, and a high flow sports muffler, this means exhaust flow is promoted throughout the whole exhaust system taking getting hot exhaust gasses out and away from your vehicle.

SOUND

Not only does a Domin8r Exhaust increase your vehicles performance, response, and even fuel efficiency, but the exhaust note produced by the Domin8r systems is music to our ears! With a less restricted system, you can hear the engine responding to any accelerator input, and you can even hear the whistle of your turbo!

Some people are happy with the sound but for off-road applications require even more volume, this is where our Domin8r Muffler Delete kits come in handy!

By removing the Domin8r Exhaust Muffler from both the 409 Stainless steel and the Aluminised steel and inserting a muffler delete kit, customers feel even more response and a much louder exhaust tone, which many find suits their taste much more!

By adding a Domin8r exhaust system to your vehicle, you will be able to feel your engines response increase instantly and give you better fuel economy, paying itself off in no time!

With easy DIY installation and far more affordable than you could imagine. Today is the day you should add a Domin8r Exhaust to your vehicle!
