A satisfying performance build starts with parts that work well together. The charge piping needs to suit the engine. The intercooler needs to match the application. The exhaust hardware should support the sound and performance goals you have in mind.

Evolution Racewerks, often called ER, offers upgrades that address those areas with vehicle-specific components. At Extreme Power House, our selection includes charge pipes, turbo-to-intercooler piping, intercoolers, downpipes and midpipes for a range of enthusiast vehicles.

BMW is a major part of the lineup, with products for several generations of turbocharged four-cylinder, six-cylinder and V8 applications. The range also includes Audi A4 B7 intercooler systems, Toyota Supra downpipes and Alfa Romeo Giulia and Stelvio 2.0-liter exhaust upgrades.

Whether you are developing a familiar N54 project or planning the next change to a newer performance car, Evolution Racewerks gives you hardware worth considering for the job.

Start with the Parts That Carry the Boost

Charge pipes are an important part of a turbocharged engine’s airflow path. They carry compressed air between components, and their construction, routing and connections all matter to the finished setup.

Evolution Racewerks charge pipe products offer aluminum alternatives to selected factory plastic or rubber components. Depending on the application, features include mandrel-bent tubing, CNC-machined connections, beaded pipe ends and supplied couplers or clamps.

For owners planning additional boost, these are useful details to consider before focusing only on the next power figure. A properly matched pipe and secure connection can address a potential weak point in the system and help prepare the vehicle for its intended modifications.

ER also offers different sections of piping. A main charge pipe, a turbo-to-intercooler pipe and a lower intercooler pipe do different jobs, so you can choose the component your particular project requires. That application-specific approach makes the range relevant to both focused replacements and more extensive hardware upgrades.

BMW N54 and N55: Keep Developing a Proven Enthusiast Platform

N54 and N55 BMWs remain rewarding cars to modify, and the Evolution Racewerks range gives owners plenty of supporting hardware to explore.

For selected N54 applications, XPH offers charge pipes for vehicles such as the 135i, 335i, 535i and Z4 sDrive35i/35is. Different versions address the relevant chassis, pipe layout and valve configuration.

The Z4 N54 charge pipe, for example, is listed for use with factory or compatible factory-style diverter valves. It uses aluminum tubing, machined connections and supplied installation hardware, with finish choices that can complement the rest of the engine bay.

N55 owners can browse products for E- and F-chassis applications. Our range includes turbo-to-intercooler piping for selected 335i, 435i, M135i, M235i and original F87 M2 vehicles, as well as dedicated charge pipe and lower intercooler pipe listings for selected 535i, 640i, X5 and X6 applications.

This breadth is especially useful when your car falls outside the most frequently discussed coupe and sedan builds. A 535i or X5 project still deserves hardware designed around its particular engine bay and connections.

Cooling Upgrades for a More Complete Build

Supporting a turbocharged setup also means paying attention to charge-air temperature. An intercooler removes heat from the compressed intake air, making cooling capacity an important part of a performance plan.

Evolution Racewerks offers Competition Series front-mount intercooler systems for selected BMW applications, including N20/N26-powered models, N55-powered 335i and 435i vehicles, and an N54 Z4 kit.

The ER Z4 Competition Series intercooler uses a bar-and-plate core and is designed to retain the factory intercooler location. Its product description explains the attention given to charge-air cooling and the relationship between the intercooler, surrounding airflow and radiator layout.

For the enthusiast, the appeal is a cooling upgrade developed as a system for the vehicle. Core design, end tanks, piping and installation layout all contribute to that system.

An intercooler is worth evaluating alongside tuning and charge piping, especially when the project involves repeated performance use. The appropriate combination depends on the engine, installed hardware and operating conditions, rather than a single advertised gain.

Audi A4 B7 Owners Have Two Cooling Approaches to Explore

Evolution Racewerks extends its intercooler range beyond BMW with products for the Audi A4 B7 2.0T.

At Extreme Power House, Audi owners can compare the Sports Series Dual Side Mount Intercooler upgrade with the Competition Series Front Mount Intercooler kit. These offer two distinct layouts for developing the car’s cooling setup.

The Sports Series dual side-mount system appeals to owners who want an upgrade without the visible appearance of a front-mounted intercooler. The Competition Series FMIC takes another approach, using a large bar-and-plate core and aluminum piping as part of the kit.

The listed B7 Competition system includes a 20-by-11-by-3-inch core, with pipe sizes selected around the system’s airflow requirements. Its supplied piping replaces the original hoses and piping, making it a more comprehensive change than a core swap alone.

For an A4 B7 owner planning a tuned or more extensively modified build, these options give you a useful choice in layout, appearance and the scope of the cooling upgrade.

BMW M Applications: S55 Piping and S58 Exhaust Options

BMW M cars are another important part of the Evolution Racewerks selection at XPH.

For the S55-powered F80 M3, F82/F83 M4 and F87 M2 Competition, ER offers charge pipes that replace the turbo-to-intercooler piping. The listed kit uses 6061 aluminum and includes threaded provisions for compatible auxiliary injection or boost-reference equipment.

That combination gives owners a way to update the charge-air hardware while considering future modifications. The supplied ports provide flexibility for an appropriately designed setup, without requiring every owner to use them.

For newer S58 applications, our range includes Competition Series midpipes for the G80 M3 and G82 M4, along with dedicated G87 M2 products. Selected Sports Series resonated midpipes are also offered for the G87 M2 and F97/F98 X3 M and X4 M.

These products let M-car owners explore the exhaust side of the build as well as supporting engine hardware. A resonated configuration offers a different approach to sound shaping, while the complete exhaust combination determines the final character.

Toyota Supra Downpipes for Four- and Six-Cylinder Applications

Toyota Supra owners can find dedicated Evolution Racewerks Sports Series downpipes at Extreme Power House.

For the 3.0-liter B58 Supra, the range includes a 4.5-inch high-flow catted downpipe. Its listed design incorporates a 200-cell metallic catalyst, giving owners a specific exhaust component to evaluate as part of a broader build.

Four-cylinder Supra applications also have dedicated options. XPH lists separate products for the B48 EU/Asia-spec configuration and the B46 US-spec configuration. That market distinction is important when selecting hardware: matching the engine and regional specification is more useful than shopping by the Supra name alone.

A downpipe forms part of the exhaust path immediately after the turbocharger, so the right choice needs to suit the vehicle’s hardware and calibration requirements. Consider the overall exhaust plan and the product’s stated use restrictions before ordering.

For both engine versions, ER gives Supra owners an application-specific option to compare when developing the next stage of the car.

Alfa Romeo Giulia and Stelvio 2.0L Performance Hardware

Evolution Racewerks also offers a Sports Series 4-inch metallic high-flow downpipe for selected Alfa Romeo Giulia and Stelvio 2.0-liter applications.

This brings another manufacturer into the ER range at XPH and gives Alfa owners a product developed around their turbocharged four-cylinder platform. The listed downpipe uses a 200-cell metallic catalyst and is offered with selectable finishes.

For a Giulia owner, the exhaust may be part of a wider plan to bring more character to the sedan. For a Stelvio owner, it can form part of a performance-focused SUV project. In either case, the important starting point is the specific 2.0-liter application; this listing should not be treated as a part for the different Quadrifoglio powertrain.

Including Alfa Romeo alongside BMW, Audi and Toyota reflects the range of projects that Evolution Racewerks can support.

Choose the Details That Suit Your Build

The most useful performance parts combine their intended function with thoughtful construction and fitment.

Across selected ER charge pipe products, you will find features such as factory-style O-ring connections, machined sensor flanges, beaded ends and silicone couplers. These details influence how the component connects to the surrounding hardware and how the system comes together during installation.

Selected products also offer finish choices, including brushed aluminum, polished aluminum and black anodizing. A polished finish can become a visible feature in the engine bay, while black offers a more understated appearance.

Before ordering, confirm your chassis, engine, drivetrain and the specific version required by the listing. Some products have additional distinctions involving transmission type, diverter valves or regional specification. Product-specific installation and use notes are part of choosing the correct component.
