The ARM Motorsports N26 Downpipe is the best hardware upgrade to get the most power from your 228i, 320i, or 328i. The N26 has a stock downpipe with a large catalyst that drastically restricts exhaust flow. An N26 downpipe upgrade is the first hardware upgrade every N26 owner should invest in.
By reducing the back-pressure on your turbocharger, the ARM N26 Downpipe prepares your 228i / 320i / 328i for higher boost tunes. In addition to helping your N26 make more power and torque, it also opens up the otherwise tame exhaust note. Coupled with a midpipe or full exhaust your N26 can produce a noticeably stronger exhaust note. The ARM N26 Downpipe connects to any aftermarket exhaust that is compatible with the stock N26 downpipe. The ARM N26 Downpipe features two O2 sensor bungs to allow for reinstallation of the OEM oxygen sensors.
