Frequently Asked Questions
What are the primary advantages of upgrading to a 3.5-inch exhaust system?
The 3.5-inch system offers maximum exhaust flow for high-performance builds. While the standard 3-inch system is perfect for most applications, the 3.5-inch upgrade is ideal for those running larger turbochargers, aggressive fueling, or high-boost setups, as it provides the least possible restriction for massive power output and further reduces EGTs.
Is a 3.5-inch system overkill for a standard 4.2L 79 Series?
For a standard or mild-tune engine, a 3-inch system is generally optimal. The 3.5-inch system is a specialized upgrade for owners looking to extract peak performance or those who have already completed significant engine modifications (like upgraded injectors and turbo). If you have a highly modified engine, the 3.5-inch will help you achieve the absolute best performance possible.
Will the larger 3.5-inch pipework fit under my 79 Series ute without modifications?
Yes. Despite the larger diameter, our 3.5-inch system is precision-bent to follow the factory chassis routing. We have carefully engineered the bends and hangers to ensure it clears the chassis, transmission, and fuel lines just like our 3-inch systems, allowing for a bolt-on fit even with the increased pipe size.
Does the increased diameter affect the sound profile?
Yes, the 3.5-inch system produces a deeper, more aggressive note. The increased volume in the pipework changes the exhaust resonance, giving the 4.2L engine a very distinct, powerful sound. We still maintain our signature drone-free cruising, but you will notice a more authoritative presence when you really put your foot down.
Is this system available in stainless steel?
Absolutely. We provide this system in our premium-grade stainless steel to ensure it holds up against the toughest off-road conditions, mud, and salt. Given the high-performance nature of the 3.5-inch exhaust, stainless steel is the ideal choice for long-term durability and resistance to the high exhaust temperatures associated with high-output builds.
