If you love driving but don’t love the constant roar of your car’s exhaust, you’re not alone. For many Subaru WRX owners, a loud exhaust has been a long-standing source of frustration. It’s fun during a spirited drive, but not so great when you’re trying not to wake up the whole neighborhood.
Whether you want an upgrade, are curious how much a loud exhaust costs in India or elsewhere, or need to repair yours, smart exhaust systems give your ride the best of both worlds. This review breaks down a hands-on exhaust upgrade using the Xforce Varex Smart Box on a Subaru WRX and explains what you need to know about exhaust prices, options, and repairs for cars and bikes.
The Big Problem with Loud Subaru WRX Exhausts
Some Subaru WRX models are famously noisy, especially with a 3-inch exhaust that comes standard on many turbocharged cars. As a driver who has owned one of these cars for years, I can say that the noise is both a blessing and a curse. It’s great when you want to hear the engine howl, but not when you’re leaving early in the morning or pulling in late and hoping not to wake the neighbors.
For many, the noise stops being fun after a while. Most WRX drivers reach a point where they want something that makes the car sound sporty but not so loud that it draws the wrong kind of attention. Balancing that love for the classic Subaru rumble with the need for peace and quiet is tough. Daily life means idling at traffic lights, driving through neighborhoods, and wanting your car to blend in, not stand out.
Finding the Right Exhaust Quieting Solution
The WRX isn’t short on exhaust options, thanks to more than two decades of aftermarket development. If you own a WRX or you’re looking for bike exhausts, you’ll find everything from basic replacements to high-tech upgrades. Here’s what most WRX owners want from an exhaust system:
Key features for an ideal exhaust system:
- Quiet operation during everyday use and city driving
- Loud, sporty sound available on demand for mountain drives or track days
- No loss of performance
- Long-lasting durability
The Xforce Varex exhaust with Smart Box caught our eye because it promises smooth switching between quiet and loud modes while keeping engine performance strong. This system also includes a smart Bluetooth-connected controller, letting you set your exhaust’s loudness from the driver’s seat.
If you’re hunting for an original exhaust price in India, prices range by brand, model, and material. A high-quality stainless system will cost more, while a bike exhaust under 500 rupees will be a more basic steel version.
Inside Performance Exhaust: The Pros Behind the Install
Performance Exhaust in Knoxfield, Australia, is known for custom fabrication and exhaust modifications. Owner David Robinson has run the shop since 2003, but the workshop’s history goes back much further. They handle custom parts for everything from old classics to new imports, and they ship across Australia.
Making High-Quality Systems
Much of the work is done in-house, using jigs and mandrel-bent pipes to ensure every system fits and sounds right. They offer everything from heavy-duty mufflers for four-wheel drives to complete stainless systems for performance cars. Many systems are built in batches and pre-made for sale online.
Safety First
During installation, the team always uses “anti-surge” protection. These devices clamp to the car battery, just like jump-starting, to prevent stray electrical current from damaging sensitive electronics like the ECU.
If you’re searching for exhaust repair near me or want a shop that specializes in WRX or European cars, a place like Performance Exhaust is a smart bet.
Trusted Brands
The team regularly recommends Xforce products, citing their fit, sound, and durability for Japanese and European cars. Properly designed systems last longer and look better, avoiding the headaches that come with cheap or worn parts.
Wondering, “How much does an exhaust pipe cost?” For a mild steel system, expect a lower price, but if you want stainless steel or a variable-valve system, prices can climb higher. For repair, a loud exhaust repair kit or exhaust pipe repair sleeve is much less than a full replacement, and loud exhaust repair cost will depend on labor and parts.
Diagnosing and Fixing Existing Exhaust Issues
- Assess the Old Exhaust
On the WRX, the old exhaust was a mix of stainless and mild steel sections. The mild steel had started to rust, and the muffler packing was breaking down, making the car louder and less efficient. - Spot the Danger A major problem was discovered: the wrong dump pipe had been installed, which actually rubbed against the steering knuckle. Under hard cornering or acceleration, this could cause the steering to lock up—a serious safety risk.
- Fixing the Issues The old system had a recently replaced catalytic converter, but the dump pipe needed to be swapped for the correct one. Using the right model for the post-2003 WRX ensured no more steering interference.
Why The Right Parts Matter
Using the correct exhaust components is key. It avoids dangerous situations and keeps your car driving as intended. If you have a broken exhaust pipe repair cost question or want to know, “How to fix a broken exhaust pipe without welding?” you can try solutions like exhaust repair tape or sleeves, but replacing incorrect or overly worn parts is safest long-term.
Comparing Old and New: The Xforce Varex Difference
Old System:
- Mix of stainless and mild steel, prone to rust
- An incorrect dump pipe caused steering problems
- Muffler packing was deteriorating
- A partially blocked catalytic converter hurt performance
New System:
- Full stainless steel, including a properly-cast dump pipe and flexible joint
- All flange plates lined up to prevent rubbing and improve fit
- Gasket goo used on all connections to prevent leaks
- The new flexible joint and correct dump pipe eliminated steering interference
- Cleaner, more efficient exhaust flow
How much does an exhaust pipe cost? The price for a complete stainless steel system is higher than basic replacements, but you get longer life, better sound, and a safer fit. Repairs, using an Exhaust Repair Kit, can be a budget option if your current system just has mild leaks or wear.
Smart Control: How the Xforce Varex & Smart Box Work
Old systems used vacuum controls or basic open/close setups, but electronic systems like the Xforce Varex Smart Box plug into your car’s OBD port. Most cars after 1996 support this feature, including nearly all modern sedans, hatchbacks, and even older models like the WRX.
Tailor Your Exhaust Note
The Smart Box system lets you set four different exhaust valve positions: closed, 25%, 50%, 75%, or fully open. You can program these settings to match your style—quiet at low speed or idle, loud on the track or up a mountain road. Everything is controlled via Bluetooth, so you can tweak settings through your phone or a remote switch.
During a test in neutral, you can hear the valve open and close. While driving, the system automatically responds to your throttle, speed, and RPM, opening up for power or closing down for quiet. This gives you a custom sound profile at the push of a button.
Real-World Results
When the valve is closed, the WRX sounds almost stock—neighbors won’t hear you arrive. In open mode, it’s throaty and deep without being painfully loud. You can actually have it both ways, whenever you need.

Installing and Maintaining Your New Exhaust

- Route the Smart Box wiring through the boot or interior trim. Hide cables for a clean look.
- Bolt all flanges and use gasket goo to prevent future leaks.

- Use a “garden hose stethoscope” to listen for any signs of leaking.

- Run the car and check for leaks at every joint.
- Pay attention to new rattles—sometimes tightening connections or adding a rubber buffer will help.
- Adjust Smart Box settings to match your daily drive or track needs.

- For small holes or cracks, an exhaust repair tape or kit can help until a proper fix is done.
