PROFILE

The ARM Motorsports N20 Downpipe is the best hardware upgrade to get the most power from your 320i or 328i. The N20 has a stock downpipe with a catalyst that drastically restricts exhaust flow. An N20 downpipe upgrade is the first hardware upgrade every N20 owner should invest in.

CONSTRUCTION

The ARM N20 Downpipe features two O2 sensor bungs to allow for reinstallation of the OEM oxygen sensors. An tune or CEL Delete will be required to avoid a check engine light from displaying on instrument panel. By reducing the back-pressure on your turbocharger, the ARM N20 Downpipe prepares your 320i / 328i for higher boost tunes. Coupled with a midpipe or full exhaust your N20 can produce a noticeably stronger exhaust note. The ARM N20 Downpipe connects to any aftermarket exhaust that is compatible with the stock N20 downpipe.
