The VA Motorsports Catless Downpipe for BMW’s N55 engine is built for drivers who want real gains—not just numbers on paper, but sharper response, more boost, and that raw turbo sound that turns heads. Designed for the E8X 135i and E9X 335i, it removes the restrictive factory catalytic converter, opening up exhaust flow and cutting down backpressure where it matters most.

With less resistance, the turbo spools up quicker and more efficiently. That means better throttle response, stronger torque delivery, and a noticeable bump in power across the rev range. You’ll feel it as soon as you hit the gas—and you’ll hear it too. The exhaust note deepens, the turbo whistle sharpens, and the car finally sounds like it has something to say.

This downpipe is made from high-grade stainless steel, mandrel-bent for smooth, uninterrupted flow. The welds are clean, the fit is tight, and the design is focused entirely on performance. No coatings, no frills—just solid, purpose-built hardware that’s made to handle heat and hard driving without compromise.

By freeing up the exhaust path, this upgrade helps the engine run cooler and more efficiently, especially under load. It’s the kind of change that doesn’t just show up on a dyno—it shows up every time you get behind the wheel. More urgency. More feedback. More reason to keep your foot down.

If your N55-powered 135i or 335i is still running the stock setup, you’re leaving power on the table. This catless downpipe is your first step toward a faster, more responsive, and better-sounding car.

Material

304 Stainless Steel

PREPREG is a common term for a reinforcing fabric such carbon which has been pre-impregnated with a resin system. This resin system (typically epoxy) already includes the proper curing agent. As a result, the prepreg is ready to be laid into the mold without the addition of any more resin. In order for the laminate to cure, an autoclave production process is used, a combination of high pressure and heat.

  • Maximum strength and performance characterictics. In a hand layup production process, it is difficult to achieve 50% fabric and 50% resin content.  Typical hand laminates, even when vacuum bagged, end up with a significant amount of excess resin. Excess resin increases brittleness and reduces overall strength properties. On the other hand, most prepregs contain around 35% resin. This is ideal for maximum cured properties and generally impossible to achieve in normal hand lamination.
  • Uniformity and repeatability. The prepreg is of uniform thickness and each part coming out of the mold may theoretically be the same. Vacuum bagging technology may have some errors in processing, but prepreg ensures production consistency.
  • Reduce curing time. After the thermal curing cycle, no need to wait for the standard 48 hours can be fully cured.
  • Aesthetics. Although prepreg processing still requires mold preparation and demoulding, prepreg processing eliminates air bubbles, makes it easier to obtain a smooth, glossy surface as well as eliminates any seaming lines.
