You’ve dropped serious cash on the bar work, the massive lift, and the custom canopy. Your 79 Series looks like an absolute weapon from the front and the sides. But walk around to the back... and what do you see? A single, flimsy factory tailpipe hanging weakly under the tray.
It doesn't look right, and it certainly doesn't sound right. You didn't build a tough rig just to sound like a whisper on the tracks. It’s time to balance out your build and fix the rear end of your Cruiser for good.
We’ve heard you. And we’ve built exactly what you’ve been waiting for.
NEW RELEASE: The 4” Twin Exit Exhaust System
Introducing the most aggressive 79 Series system we have ever built: the all-new Twin Exit 4” System.
Engineered for maximum flow, massive sound, and bold rear styling with dual massive 4-inch outlets exiting symmetrically at the rear. This isn't just an exhaust replacement; it is the ultimate visual and acoustic statement for serious 79 owners.
Why Choose the 4” Twin Exit?
- Massive Visual Impact: Dual 4” rear exits completely transform the posture of your rig.
- The Signature Roar: Delivers a huge, unmistakable Manta exhaust tone.
- No Compromise Flow: Specifically designed for high-performance builds chasing max power.
- Overbuilt: Engineered to withstand relentless towing, long-distance touring, and brutal off-road durability.
Configure It Your Way
When choosing the #1 performance exhaust in Australia, you dictate the rules of your build. The new 4" Twin is available in configurations built to match your lifestyle:
- Turbo-Back vs. DPF-Back: Choose a Turbo-Back system to unleash the absolute full performance potential of your engine. Need to stay fully emissions-compliant? Grab the DPF-Back version for massively improved sound and flow while retaining factory emissions equipment.
- Pick Your Volume: Want an earth-shaking roar? Select our No Muffler option for a loud, raw, and aggressive tone. Prefer something powerful but smooth? Our Muffler option delivers a deep, refined growl.
- Premium Materials: Available in Heavy-Duty Aluminised Steel (for tough value) or Premium Full Stainless Steel (for maximum rust resistance and lifespan).
Built loud. Built tough. Built for Australia.
SCROLL DOWN TO EXPLORE OUR FULL 79 SERIES RANGE
Not every rig needs a 4" twin exit. Depending on your tray setup, tune, and suspension, we offer an entire lineup of proudly Australian-made aftermarket performance exhaust systems for your Cruiser.
The Aggressor: 4” Side Exit Exhaust System
Built for owners who want serious, raw presence. By exiting aggressively right in front of the rear wheel, this setup delivers a tough, performance-driven stance that cannot be ignored.
- Best For: Heavy off-road use, performance builds, and owners chasing the most aggressive sound profile in the lineup.
- Available Variants: DPF-Back or Turbo-Back (with/without a Cat). Choose between a loud, medium and quiet exhaust setup by selecting your preferred muffler configuration.a
Big-bore performance with a clean, classic rear exit look.
Our 4” Single Rear Exit systems deliver excellent flow, deeper tone, and improved throttle response while maintaining a traditional rear exit style. Perfect for drivers who want strong performance gains without the side-exit configuration.
The Touring King: 3” Twin Exit Exhaust Systems
Want the gorgeous, symmetrical aesthetic of a twin-rear exit, but without stepping up to a massive 4” pipe? The 3" Twin is your answer.
- Best For: Touring-focused builds, towing caravans, and daily-driven Cruisers.
- The Advantage: Keeps exhaust velocity high for incredible low-end torque. You get a deep, beautifully controlled tone without deafening the kids in the back seat on a long trip.
Engineered Compatibility: Perfect Fitment Every Time
A premium exhaust means nothing if it doesn't fit your rig’s specific modifications. Our Manta performance engineers have done the hard yards. These systems are specifically engineered to accommodate:
- The VDJ79 4.5L V8 & the newer GDJ79 2.8L engines.
- Both Single Cab and Dual Cab chassis layouts.
- Vehicles equipped with aftermarket Long-Range fuel tanks.
- Heavy-duty touring suspension setups.
Every system is fabricated in-house to guarantee precise fitment and absolute long-term durability in punishing Australian outback conditions.
