Have you ever wondered just how much of a difference an aftermarket exhaust system could make for your 4×4? There’s no shortage of claims about the increased output, improved fuel economy, and richer sound that aftermarket systems have over OE tubes, but how true are they?
The fact is, these are three very real, and wholly attainable benefits that aftermarket exhaust systems can offer. A lot depends on the level of quality the manufacturer puts into the system though, and that includes everything from the materials they use to the precision of each system’s fitment. Everything begins with engineering; and fortunately, there’s an aftermarket exhaust manufacturer right here in Australia who understands that in order to get the best performance out, the highest degree of engineering excellence needs to go in.
Manta Manufactures 4×4 Exhausts in a Class All Their Own
It doesn’t matter if your 4×4 is the family’s dedicated daily driver or your personal weekend off-road warrior, an aftermarket exhaust system has the ability to reshape how you feel about your vehicle. Unlike other aftermarket enhancements, only high-performance 4×4 exhausts make boosting your engine’s output as easy as a bolt-on; and no one knows how to design exhaust systems better than Perth’s Manta Pro.
With more than 50 years of experience in crafting some of the finest, and most exclusive exhaust systems around, Manta specialises in exhaust systems for both regular production, as well as custom 4x4s and off-road vehicles, each with an emphasis on delivering:
- A significant improvement in throttle responsiveness;
- A measurable increase in low-end torque; and,
- Greater top-end peak power.
Regardless of the application, Manta’s commitment to expert engineering and maximized performance is what distinguishes their exhaust systems from all others. They know that it takes more than just a set of big pipes to make a 4×4 exhaust system that performs as well as it sounds, which is why they’re in a class all their own when it comes to the dynamics behind power, sound, and even fuel economy.
All the Premium Qualities That You Expect From a Premium Exhaust
Flow dynamics, together with expert knowledge of how velocity, turbulence, and pressure affect the movement of hot gases are the most crucial aspects of 4WD exhaust design, and Manta systems are designed to be among the industry’s most efficient when it comes:
- Promoting improved high-pressure flow, and low-pressure scavenging of spent exhaust gases and heat away from the engine;
- Maximizing, and stabilizing the velocity of spent gases moving throughout the full length of the system; and,
- Minimizing the causes of turbulence and back pressure that can effectively choke an engine if exhaust gas scavenging and velocity are improved.
These principles are the basis of every well-engineered exhaust, and Manta balances and dyno tests all of their 4WD exhaust systems to ensure that it maximize your engine’s torque and power curve. Gains of up to 15% more power and 50 – 100km more per tank of fuel are achievable simply by opting for a premium Manta 4×4 exhaust upgrade; and with their wealth of exhaust system configurations, you can be sure that they have a high flow, CNC designed system that’s perfect for your vehicle.
ADR Compliant Configurations For Every 4×4 Engine
With a low restriction exhaust selection that covers practically every 4-, 5-, 6-, and 8-cylinder turbocharged, supercharged, and naturally aspirated 4×4 engine sold in Australia, Manta’s standard range of tubes, manifolds, and mufflers is as extensive as they are effective. Their full lineup of ADR (Australian Design Rule) compliant, mandrel bent, 2.5“ and 3.0“ 4×4 performance exhaust systems are available in a wide range of configurations that include:
- Single and dual extractor systems, offering 3-into-1 and 4-into-1 header pipes, collectors, or dumps;
- Cat-back, DPF back, or full-length H-, X-, or Y-tube setups with braided flex joints; and,
- A choice of glass-packed or baffled mufflers or resonators, with single or dual endpipes, or twin sidepipes for the perfect sound.
Not surprisingly, these bolt-on configurations are designed to mount directly to OE mounts, and don’t require any cutting or welding to achieve a no-leak, OE-quality fit. This is especially important as the moisture, vibration, and extreme temperatures that 4×4 exhaust systems are commonly exposed to can lead to a host of damages and stresses that could contribute to crushed or busted tube welds, muffler or catalytic converter problems, and overall poor scavenging.
Manta also knows that good configurations alone aren’t good enough. Durability is as much a part of exhaust design excellence as engineering, and that’s why they only use materials and coatings that are tough enough to take on Australia’s most demanding environments.
It Takes Good Materials to Build Great Exhausts
If there’s any question about how much of a difference there is between OE, and superior quality aftermarket 4WD exhausts, you only need to look at the materials. From manifold to muffler, mass-produced, factory cast iron exhaust systems are undeniably tough, while still being relatively inexpensive to manufacture or replace. However, they’re also dreadfully heavy; plus they’re magnets for corrosion, and a proper headache to repair, especially if you’re on the road.
Manta relies heavily on lightweight aluminized, and automotive grade 409 stainless steel for the bulk of their 4WD performance exhaust systems. Weighing just 30% of their OE equivalents, TIG-welded, titanium-stabilised 409 tubes offer the absolute best balance of weight and reliability, are easily repaired when damaged, and feature a range of material advantages that include:
- High tensile strength and thermal expansion properties;
- Continuous heat resistance to 675°C, with periodic resistance to 815°C;
- 60% greater heat transfer capacity than other stainless steels;
- Greater resistance to environmental gates like rust and exhaust gas corrosion; and,
- Greater resistance to mechanical gates like heat cycling and excessive vibration.
Manta also applies heat-resistant coatings to their turbo dump pipes, as well as headers and mufflers. It’s a process that locks heat inside the system where it helps improve scavenging by decreasing exhaust gas density; and it’s a full treatment that they can apply to any of their one-off, custom exhaust systems.
The Final Word
At the end of the day, it doesn’t matter what kind of 4×4 you own, you want to get the best sound and performance out of it that’s possible, but you don’t want to sacrifice everyday driveability, or break the bank doing it. Only aftermarket exhaust systems offer all these benefits, and only one company in Australia has the expertise to deliver them without compromise.
When it comes to high-performance 4×4 exhausts, Manta Pro has everything you need for any ADR-compliant configuration, for any Aussie 4×4. From economical 4-cylinders to stump-pulling 8-cylinders, you can count on Manta to help you get the most from your engine.
