More Power. Better Sound.
At Atherton Mechanical Services in Atherton, we build performance exhaust systems for drivers who want sharper throttle response and a stronger, cleaner note. We fabricate each system in-house, shaping and welding to suit the engine rather than adapting a universal kit to fit.
When we upgrade your exhaust, we focus on how you actually drive — daily commuting, weekend runs or towing. We design the system to improve flow without sacrificing reliability. If you’re ready to upgrade to a performance exhaust, call (07) 4091 6556 and book your build.

Frequently Asked Questions
These are common questions drivers ask when researching performance exhaust upgrades and what they can realistically expect.
How much power does a performance exhaust add?
Power gains vary depending on engine size, turbo setup and existing modifications. Naturally aspirated engines may see modest improvements in throttle response and top-end power, while turbocharged engines can benefit more noticeably from reduced back pressure. Results depend on correct sizing, pipe design and overall system layout rather than simply increasing diameter.
Will a performance exhaust make my car too loud?
Sound level depends on pipe size, muffler type and resonator choice. A well-designed performance exhaust can produce a deeper tone without excessive cabin drone. It is possible to balance performance and comfort through careful component selection and layout, especially when the system is built specifically for the vehicle.
Is a 3-inch exhaust better for performance?
A 3-inch exhaust is common on turbo diesel and some turbo petrol engines because it can improve exhaust flow under load. However, bigger is not always better. Oversized systems can reduce low-end torque if not matched properly. The ideal diameter depends on engine configuration and intended use.
Built For Real Gains
A performance exhaust isn’t just about noise. We look at pipe diameter, bend angles, muffler selection and overall routing to support efficient gas flow and balanced sound. By fabricating and pipe bending in-house, we control how the system fits and performs. That allows us to tune the setup for stronger mid-range response, smoother delivery and long-term durability.
