How Good Are Pacemaker Exhaust Systems?

Date Posted: 14 January 2025

When talking about performance exhaust systems, if you’re an Aussie, one name consistently comes up - Pacemaker exhausts. That’s not surprising, as Pacemaker has been revolutionising the industry for decades. From cutting-edge technology like mandrel bending to their iconic pipe-over-cone design, they’ve set the bar for what drivers expect from premium exhaust systems. However, let’s go a bit deeper and see what makes Pacemaker truly stand out.

The Tech Pioneering of Pacemaker Exhausts

First and foremost, Pacemaker exhaust systems have long been recognised for their pioneering approach to exhaust technology, blending innovation with high-quality manufacturing. As the first company to introduce mandrel bending technology to the exhaust header market, Pacemaker set a new standard.

Mandrel bending involves inserting a flexible support or ‘mandrel’ into the pipe during the bending process, which prevents the pipe from collapsing or deforming. This technique ensures that the pipe maintains a consistent diameter throughout the curve, a key factor in maintaining smooth and uninterrupted airflow.

In contrast, traditional press bends create restrictions by compressing and distorting the pipe’s shape, leading to reduced flow efficiency and potential performance loss. With mandrel bending, exhaust systems benefit from improved airflow dynamics, reduced turbulence, and more consistent pressure levels, ultimately resulting in better engine output.

On top of that, Pacemaker's extensive range includes advanced 4-into-1 and Tri-Y collector designs that are engineered to optimise exhaust gas extraction from the engine. These configurations improve cylinder scavenging and reduce backpressure, resulting in better power output and efficiency. The Tri-Y design, in particular, is favoured for its balance of performance and versatility, making it ideal for both street and track applications.

To ensure durability and performance, Pacemaker also incorporates a shot peening process into its manufacturing. This aviation-inspired technique smooths surfaces, removes impurities, and strengthens components by relieving stress points, which helps extend the lifespan of the headers.

With a legacy of technical innovation and commitment to quality, Pacemaker has cemented its reputation as a leader in exhaust engineering, so you may think that they decided to rest on their laurels. That’s not the case. These prior advancements only set the stage for their signature innovation - the pipe-over-cone technology, which revolutionises exhaust flow and longevity.

Pipe-Over-Cone Tech

Traditional header designs often rely on a welded flange or slip joints to connect pipes; while functional, these methods can create points of turbulence where gases meet, reducing the overall efficiency of the exhaust system. Pacemaker’s innovative pipe-over-cone approach eliminates this issue by integrating a smooth, overlapping transition at the collector.

This design ensures that exhaust gases flow seamlessly from one pipe to the next without encountering interruptions. By reducing turbulence and preserving velocity, this technology improves power delivery and contributes to a quieter, more refined exhaust note. It’s a win-win for performance enthusiasts looking to maximise output without compromising on everyday drivability.

But that’s not all - durability is another major advantage of this design. The pipe-over-cone connection eliminates weak points like welds that could crack under extreme heat or vibration. The result is a header system built to withstand the rigours of high-performance applications, whether on the street or the track.

This innovative technology is a perfect example of Pacemaker’s commitment to pushing boundaries in exhaust design. By combining performance, durability, and craftsmanship, the pipe-over-cone system redefines what drivers can expect from a premium exhaust system, and there are no indications that Pacemaker will stop innovating any time soon.

Pacemaker’s Product Lines

When it comes to specific products, Pacemaker is best known for their lines of headers (which you probably could have guessed based on all the effort they put into advancing the tech), but they also manufacture whole performance exhaust systems, as well as accessories.

Pacemaker Headers

An essential component of Pacemaker exhausts - Pacemaker headers (for Ford Falcon).

Pacemaker’s headers are the company’s flagship product line, and it shows. Their headers alone make them one of the best exhaust brands in Australia, even if you disregard all other products. Just one example is the Big Block Tri-Y header for the Ford Falcon 460, designed to deliver superior scavenging and exhaust flow. All headers come with a two-year warranty, ensuring peace of mind for enthusiasts and professionals alike.

4x4 Exhaust Systems (King Brown) and Sports Exhaust Systems

If you’re not just looking for headers, don’t worry; Pacemaker also manufactures whole exhaust systems, applying the same innovative and meticulous approach. The King Brown 4x4 exhaust line is a fan favourite among off-road enthusiasts. You’ll find a wide range of products, from the King Brown 3" cat-back exhaust system for the Nissan Patrol Y62 to the exhaust system for the Toyota Hilux GGN25R.

Built for rugged conditions, these systems are backed by an impressive five-year warranty, making them a reliable choice for extreme adventures. Similarly, Pacemaker’s sports exhaust systems cater to a wide range of vehicles, offering versatile options for drivers who want improved performance and sound. These systems also come with a five-year warranty, reflecting their durability.

Accessories

For those seeking smaller components, Pacemaker also offers a variety of accessories, from reducer cones and heat tapes to bolts and flanges, all backed by a one-year warranty for added assurance.
