Upgrade your BMW M135i, M235i, 335i, 435i, or F87 M2 with the VRSF N55 High Flow Catted Downpipe, designed to enhance exhaust flow, turbo efficiency, and overall engine performance. This high-performance downpipe replaces the restrictive factory catalytic converter with a high-flow 200-cell metallic catalyst, significantly reducing backpressure while maintaining emissions compliance and minimizing exhaust odor.

The N55 High Flow Catted Downpipe provides improved turbo spool, sharper throttle response, and noticeable horsepower and torque gains, making it an excellent upgrade for street-driven and performance-oriented BMWs. When paired with tuning, this downpipe offers increased power, enhanced drivability, and a more aggressive exhaust note without excessive cabin drone.

Crafted from premium SS304 stainless steel, the VRSF N55 High Flow Catted Downpipe features a precision-engineered design with smooth mandrel bends to maximize exhaust flow while ensuring a direct bolt-on fitment for all F2X and F3X BMWs equipped with the N55 engine. This downpipe is compatible with both stock and aftermarket exhaust systems, making it a versatile choice for enthusiasts looking to improve their BMW’s performance while retaining a refined driving experience.

VRSF downpipes are hand crafted from mandrel bent SS304 grade stainless steel and our CNC precision machined flanges are also constructed from billet 304 grade stainless steel. All VRSF products include a lifetime warranty as well as our “No Hassle” satisfaction guarantee (including fitment). All M135i & 335i models produced up to 07/13 require the 3.5″ version of this downpipe. M135 and 335i models produced after 07/13 require the 4″ model of this downpipe. All M235 and 435i models require the 4″ version of this downpipe. Please confirm by looking at your Turbo Wastegate. It is located on the lower passenger side of the engine next to the Turbo. See picture below for reference.

For additional heat management, we offer Cerakote High-Temperature Ceramic Coating, capable of withstanding temperatures up to 1800°F. This advanced thermal barrier coating helps retain heat within the exhaust system, reducing engine bay temperatures, lowering intake air temperatures, and improving engine and transmission oil cooling.

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.
