Extreme Turbo Systems Cat Back Exhaust System (Burnt Tips) P/N – 2015-WRX-CB The Cat Back Exhaust System from Extreme Turbo Systems (ETS) is constructed from 304 stainless-steel in four pieces. This TIG-welded exhaust system utilizes 76.2mm piping with 1.5mm-thick walls, with a laser-cut flange at the down-pipe attachment point and V-bands to mate the Y-pipe and two mufflers. Its construction allows it to press the scales at only 39.6 lbs., making it relatively lightweight compared to the other exhaust systems. Sound levels peaked at 92 decibels at mid-range and high RPMs, with some drone heard from inside the car. However,…

We’ve all seen videos of race leaders stumbling over the last drops of fuel in their tanks, their engines sputtering and misfiring as fuel flow sporadically cuts out. Sometimes they are lucky enough to coast past the checkered flag in first place, other times the competition catches up and blows past them at full tilt, watching their victory get snatched away at the last possible second.

Many racing sanctioning bodies require drivers to be able to exit a stopped car in only seven seconds in the case of an emergency. This may not sound like a long time, but it can feel like forever when flames fill the vehicle cabin. All the while, the driver must shut off the car, cut the power, engage the fire suppression system, release the six-point harness, remove the steering wheel, unhook the window net and open the door to get out. Each of these items play a key role in keeping a driver safe in different ways, while allowing them…

REGARDLESS OF WHETHER you’re talking about an athlete or a vehicle with a combustion engine, improving aspiration can make a tremendous difference to performance. Just as a runner trains at elevation to make breathing easier at sea level, helping a turbocharged vehicle breath easier will net horsepower gains. Text by Richard Fong // Photos by Jun Chen and Richard Fong // Testing by Jeren Walker In the last Test & Tune installment, our 2011 WRX realized a peak gain of 18.48 horsepower with just an intake, exhaust and a reflash. In this segment, we continue to search for power and…

SUBARU’S GVB WRX COULD BE ONE OF THE the best values in the segment, when measuring performance versus value. It’s less expensive than similar all-wheel drive sedans yet the WRX benefits from its torquey, turbocharged 2.5- liter EJ255 engine. When Subaru released this sedan, its bold lines and flared fenders made its silhouette difficult to discern from its big brother, the STI sedan (with exception of the rally-inspired wing). Our test platform had 35,000 miles on the odometer and enjoyed those miles in completely stock form. Baseline pulls revealed that the WRX comes underrated from the factory. Subaru advertised that the…

Excitement followed by immediate disappointment is what we experienced when we initially learned about the new Civic. We were ecstatic to hear that it would be turbocharged but those happy feelings were quickly deflated when we realized that it was only offered with a continuously variable transmission (CVT). After enough backlash (or perhaps as a result of Honda’s marketing strategy), Honda announced that the 1.5-liter turbocharged engine could be had with an optional 6-speed manual transmission. Our faith in humanity was restored as we planned to get a Civic on our dyno and begin testing the car’s response to modification.…

Whether it’s computers, phones, tablets, operating systems or music applications, Apple excels in treating its users like idiots but gets away with it by way of clever marketing. It removes control and functionality from its products while branding the changes as features. Thankfully, there are still people wiser than this on both a business and consumer level. In a world where tech companies remove features and jack up prices, AEM Performance Electronics proves that there is still hope. AEM’s CD-7 Digital Racing Dash Display give control back to the users, offering one of the most comprehensive feature-sets in the dash…

Even though today’s vehicles require less maintenance than ever before, there are still a number of items that need regular attention to keep them running just right. In this Tune-up Basics guide, we’ll cover the fundamentals that every car enthusiast should know from changing oil to setting tire pressure. Follow the steps in the individual sections and your car will be running strong for years to come. Ignition There’s No Fire Without a Spark Fluids Happy Engines are Lubed and Cooled Filters Capturing Contaminants Brakes Solid Stopping Power Electrical Voltage to Drive Settings Important Factors for Everyday Driving Car Paint…

It only takes a spark to light a fire. But if the fire needs to be lit in a turbulent environment, as is the case with a combustion chamber, you’ll need the right equipment to reliably convert ignition voltage into a spark. During the power stroke of an internal combustion engine, cylinder pressures can range anywhere from 300 psi at a light load up to 1,500 psi in some racing applications. To ignite this compressed mixture of air and fuel reliably, you need to have the right ignition components for the job. By Richard Fong What’s in a Spark? A…

Powertrains are complex systems of metal components put under the stresses of heat and rotational forces to put a vehicle into motion. Healthy fluids play a key role in keeping everything working as intended. While different fluids have different applications, their end goal is to minimize friction, reduce heat and extend service life. Fluids operate in inherently challenging environments, with contaminants and heat exposure necessitating regular changes. A properly maintained vehicle should have correct volumes of clean fluids flowing at intended operating pressures. Without fluids, a car would be doomed to imminent and catastrophic failure.

Impurities are constantly trying to find their way into your engine, undermining reliability and causing harm. Filters are the primary line of defense protecting a car from harmful contaminants. Modern vehicles utilize an array of filters, each separating foreign objects from entering vulnerable areas of the powertrain. Filters eventually reach limits of effectiveness, and need to be cleaned or replaced. Often scheduled alongside other frequent maintenance items, filter replacements are an essential part of caring for your car. Text and Photos by Stanley Yee Oil Filters As engine oil circulates through an engine and collects contaminants, it falls on the…

Proper vehicle maintenance can save you a lot of time and money, though proper brake maintenance in particular could very well save your life. This appears to be common sense, yet why do so many vehicle owners put it off? To anyone who has never done it before, brake servicing might appear too complicated or time consuming. Staying on top of the maintenance of your brakes and understanding the details of your brake system is easier than you might think, and can save you from potential future repairs.

Nothing can ruin a day of plans quicker than getting into a car that fails to start. Then again, it can be even more frustrating and dangerous when driving a vehicle that slowly begins to lose power and then goes “dead” while driving. While there is no way to avoid 100-percent of these incidents, over 90-percent can be avoided with proper maintenance and setup of a vehicle’s primary electrical system. Have you ever wondered why some vehicles are constantly burning through replacement batteries and alternators, while other vehicles get more than 10 years of service from a “5-year” battery? Understanding…

It’s easy to get overwhelmed by the number of maintenance variables that ensure the reliability and longevity of your vehicle. Fortunately, technological advances and engineering have stretched the service intervals of many wearable items. This in turn reduces the frequency of maintenance to reduce consumption and cost while simplifying the responsibilities of vehicle ownership. However, there are some basics that everyone should be conscientious of, mainly pertaining to your tires and your engine. These are simple but important default vehicle settings and practices applicable to any street vehicle. Text and Photos by Richard Fong Mechanical Traction Tire manufacturers have invested…

If you’re reading this then you aren’t normal. In fact, you’re probably abnormal in the sense that you care about you car way more than the average person. But why wouldn’t you? You dedicate your time and money to getting the most from your car. Whether it’s horsepower or handling, your car is most likely getting the best of the best in terms of performance components. So why do some of us neglect to make sure our cars look their best? If you simply don’t care if your car has a clean and shiny appearance, well there’s not a whole…
