Description

The Island Racewerks F2x/F3x/F87 N55 Dump Pipe exhaust system is meticulously engineered for drivers seeking enhanced efficiency and uncompromising performance, specifically intended for race night applications. This optimization leads to a notable decrease in wastegate duty cycle (WGDC), enabling the turbocharger to operate more effectively and with less strain. The result is a more responsive vehicle setup, improved boost control, and increased tuning headroom for aggressive engine maps. The dump pipe is constructed in the USA from premium 304 stainless steel, selected for its superior corrosion resistance, high-temperature stability, and long service life. It features proprietary CNC-machined OEM-Style flanges for a perfect seal and precise fitment, ensuring maximum durability through repeated thermal cycling. Key features include 304SS tubing, proprietary CNC OEM-style flanges, a 1/2” stainless hanger, a lifetime warranty, and it is made in the USA. This dump pipe is explicitly for "RACE NIGHTS ONLY." Fitment is confirmed for the F22 M235i (& xDrive), F30 335i (& xDrive), F32 435i (& xDrive), F33 435i (& xDrive), F35 335i GT (& xDrive), F36 435i (& xDrive), and F87 M2 (OG).
