XForce Race Exhausts: Push the Limits with These High-Performance Exhausts

Serious auto enthusiasts are under no illusions about how much of a difference high performance exhaust systems make over their factory equivalents. They know that even modest improvements in exhaust flow can mean a big step up in performance. That’s precisely why when enthusiasts need more than just modest bumps in performance, they turn to purpose-built rally- and race-ready exhaust systems for the biggest results.

High flow, dyno-tuned exhaust systems are more than just random lengths of large diameter tubes. They’re singularly engineered around flow characteristics that produce noticeably better performance. And for the latest generation of high output, high compression 2+2 sports cars from Toyota and Subaru, the difference that these exhausts can make, either on the road or at the track, are substantial.

Experience Superior Flow with Motorsport Ready Exhausts

It’s a fact: from their precision welds and premium craftsmanship, to their choice of 304 stainless steel or titanium construction, motorsport-ready race exhaust systems are a cut above even the best factory systems. They’re the perfect solution for the latest generation of rear-wheel drive 2+2s like Toyota GR86s, and Subaru BRZs and WRXs that breathe deeply and need to remove spent gases quickly.

These fleet-footed little sports cars continue to make a big impression on road tracks and rally circuits across Australia, so it’s no surprise that NSW’s own XForce has stepped up with their own core of street-legal exhaust packages that boast all the high flow characteristics of full competition systems.

XForce is passionate about aftermarket exhaust engineering and design. And with one of the most impressive competition-inspired and motorsport-oriented exhaust system lineups anywhere, their 2+2 high performance exhausts are recognised for a host of superior gas evacuation, and low restriction traits that include:

• Increased exhaust flow. XForce performance exhaust systems for cars excel at high pressure to low pressure scavenging, allowing them to draw spent exhaust gases through the system more efficiently.
• Accelerated exhaust velocity. Exhaust gas evacuation velocity is a crucial component of scavenging, and the optimized tube sizing of XForce performance exhaust systems gives them a valuable advantage when it comes to keeping gases moving quickly.
• Reduced exhaust restrictions and backpressure. Increased exhaust flow and velocity are directly related to reducing the number of in-tube restrictions; and mandrel bent curves and fully TIG welded joints and flanges are the key to maximising the removal of spent gases.

With their full range of race-tuned characteristics, XForce’s high performance exhaust systems also possess excellent heat transfer properties. It’s an essential quality for motorsport-ready aftermarket exhausts, especially on turbo-charged cars like the WRX.

Uncontrolled heat build-up from lingering exhaust gases can lead to oil coking, wastegate damage, and ultimately to complete turbo failure. That means anywhere big boost-producing turbochargers are in use, motorsport-ready performance exhaust systems are actually contributing to turbo and engine longevity.

A Full Array of Road and Track Benefits that Don’t Disappoint

While it’s easy to get lost in the technical attributes of motorsport-ready racing exhaust systems, it’s the impact they have both on and off the track that matters. An instantaneous, ADR-compliant increase in peak power is what enthusiasts expect from a serious 2+2 performance exhaust system, and Xforce cat back and cat delete systems don’t disappoint. With their dyno-tested increases in output and torque, XForce’s motorsport-ready exhaust systems are proven assets when it comes to:

• Improved acceleration. From better throttle management and launch control, to increased flexibility when climbing or heavy hauling, XForce’s race-ready exhaust systems for GR86/BRZs and WRXs offer a vast improvement in both road and track acceleration over factory systems.
• Crisper throttle response. The increased flow and reduced backpressure characteristics that are designed into each of XForce’s upgrade exhaust systems can be counted on for the crisp responsiveness that’s necessary for easier streaming, overtaking, or towing.
• A broader output and torque range. While engine power and torque curves are determined almost entirely by their design, XForce motorsport exhaust systems make it easier to widen output and torque ranges across all RPMs, especially when combined with chip or ECU tuning.

Make no mistake: from their 2.5“ – 4.0“ mandrel bent tubes and endpipes, to their high-flow stainless steel turbo mufflers and rear resonators, XForce’s motorsport-ready GR86/BRZs and WRXs race exhaust options are engineered like no other to deliver a unique blend of power and torque, both on and off the track.

It’s also no coincidence that their cutting-edge uniqueness applies to sound. XForce’s signature drone canisters are designed to deliver one of the most distinctive exhaust notes of any aftermarket performance exhaust for sale on the market. No matter if it’s on the road or track, they help keep the rumble to a minimum.

Positive Resonance Control That Doesn’t Restrict Power

Unlike the unfiltered exhaust note that’s common with competition exhausts, XForce race-ready exhausts are equipped with drone canisters. Also known as Helmholtz resonators, drone canisters are designed to cancel out unwanted resonant frequencies at specific engine RPMs without hurting power output. They’re attached ahead of the muffler where they’re in the best position to intercept unwanted sound waves; and based on their length, they boast a range of advantages that include:

• Compact size that’s tuned precisely for GR86/BRZ, and WRX powerplants;
• Elimination of the annoying exhaust drone that can occur at annoyingly low frequency ranges; and,
• The ability to maintain a motorsport-quality sound that’s aggressive, but not arrogant.

Ideally, XForce drone canisters make it easier for Toyota and Subaru 2+2 owners to enjoy the full benefit of a motorsport-ready exhaust without the risk of getting defected for excess noise. That makes them the optimal compromise when it comes to combination road and track exhausts that sound just as good as they perform.

The Final Word

At the end of the day, while high performance exhaust systems are all designed for improved exhaust flow, some systems are better than others. Rally and race-ready systems are engineered to push the limits of exhaust gas evacuation; that’s why they’re the setups of choice for Toyota and Subaru 2+2 owners who want even more than just a moderate improvement in performance. XForce’s motorsport-ready exhaust systems are the highest flowing, ADR-compliant systems in Australia. They’re an investment in performance and powertrain longevity that’s well worth making.
