Two O2 bungs let you reinstall the factory O2 sensors or block them off with the two included bolts. Running this section opens the door to more advanced boost settings on a stock or Stage 1 tune, since the high-flowing 3\" pipe lets the 2.0T handle the extra exhaust flow of higher boost targets. Two CNC-machined flanges bolt directly to the OEM exhaust and turbo, and an OEM-location mounting bracket holds it in place to reduce vibration. Without an ECU tune or O2 sensor fix, expect a check engine light — resolved with an upgraded ECU programmer or an O2 sensor fix adapter.\u003c\/p\u003e\u003ch3\u003eIn the box\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eARM 3\" Test Pipe\u003c\/li\u003e\n\u003cli\u003eHardware and gasket kit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eSubmodel\u003c\/th\u003e\n\u003cth\u003eEngine\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudi\u003c\/td\u003e\n\u003ctd\u003eB8 A4\u003c\/td\u003e\n\u003ctd\u003eFWD\u003c\/td\u003e\n\u003ctd\u003e2.0T\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudi\u003c\/td\u003e\n\u003ctd\u003eB8 A4\u003c\/td\u003e\n\u003ctd\u003eQuattro\u003c\/td\u003e\n\u003ctd\u003e2.0T\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudi\u003c\/td\u003e\n\u003ctd\u003eB8 A5\u003c\/td\u003e\n\u003ctd\u003eQuattro\u003c\/td\u003e\n\u003ctd\u003e2.0T\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudi\u003c\/td\u003e\n\u003ctd\u003eB8 Allroad\u003c\/td\u003e\n\u003ctd\u003eQuattro\u003c\/td\u003e\n\u003ctd\u003e2.0T\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudi\u003c\/td\u003e\n\u003ctd\u003eB8 Q5\u003c\/td\u003e\n\u003ctd\u003eQuattro\u003c\/td\u003e\n\u003ctd\u003e2.0T\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cp\u003eBacked by ARM Motorsports' lifetime warranty against defects in craftsmanship and fitment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eEmissions disclaimer:\u003c\/strong\u003e This product is not legal for sale or use on pollution-controlled vehicles operated on public roads and is intended for off-road, race, or closed-course competition use only.

It fits with no cutting or trimming of the OEM system and swaps in about 45 minutes with a basic tool set — so you can return to a stock muffler later if you ever want to.\u003c\/p\u003e\u003ch3\u003eIn the box\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e1x ARM B58 Single Exit Exhaust\u003c\/li\u003e\n\u003cli\u003e1x Exhaust Clamp\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eSubmodel\u003c\/th\u003e\n\u003cth\u003eEngine\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eF22\u003c\/td\u003e\n\u003ctd\u003eM240i\u003c\/td\u003e\n\u003ctd\u003eB58 3.0L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eF22\u003c\/td\u003e\n\u003ctd\u003eM240i xDrive\u003c\/td\u003e\n\u003ctd\u003eB58 3.0L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eF23\u003c\/td\u003e\n\u003ctd\u003eM240i\u003c\/td\u003e\n\u003ctd\u003eB58 3.0L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eF23\u003c\/td\u003e\n\u003ctd\u003eM240i xDrive\u003c\/td\u003e\n\u003ctd\u003eB58 3.0L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eF30\u003c\/td\u003e\n\u003ctd\u003e340i\u003c\/td\u003e\n\u003ctd\u003eB58 3.0L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eF30\u003c\/td\u003e\n\u003ctd\u003e340i xDrive\u003c\/td\u003e\n\u003ctd\u003eB58 3.0L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eF30\u003c\/td\u003e\n\u003ctd\u003eM340i\u003c\/td\u003e\n\u003ctd\u003eB58 3.0L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eF30\u003c\/td\u003e\n\u003ctd\u003eM340i xDrive\u003c\/td\u003e\n\u003ctd\u003eB58 3.0L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eF32\u003c\/td\u003e\n\u003ctd\u003e440i\u003c\/td\u003e\n\u003ctd\u003eB58 3.0L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eF32\u003c\/td\u003e\n\u003ctd\u003e440i xDrive\u003c\/td\u003e\n\u003ctd\u003eB58 3.0L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cp\u003eBacked by ARM Motorsports' lifetime warranty against defects in craftsmanship and fitment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eEmissions disclaimer:\u003c\/strong\u003e This product is intended for off-road, race, or closed-course competition use only and is not legal for use on pollution-controlled vehicles operated on public roads in most states and provinces.

It starts at 4\" at the precision CNC-machined turbo v-band, steps up to a 5\" 200-cell sport catalyst, then tapers to a flared joint that matches the stock midpipe v-band exactly. Two O2 sensor bungs let you reinstall the factory oxygen sensors, and they sit higher on the pipe so you won't stretch the sensor wires during install. A tune or CEL delete is required to keep the check engine light off.\u003c\/p\u003e\u003ch3\u003eFlashing Stage 2+\u003c\/h3\u003e\u003cp\u003eBy freeing up exhaust flow, this downpipe preps your F-Series for higher-boost tunes — if you already run software for your N55, those files are likely already loaded and waiting for you to flash after install. Most Stage 2 tunes also want a front-mount intercooler; if you don't have one yet, look at our F3X FMIC. Stage 2 N55s typically see around 400whp and 400wtq.\u003c\/p\u003e\u003ch3\u003eImproved exhaust sound\u003c\/h3\u003e\u003cp\u003eThe downpipe accounts for roughly 20% of the exhaust system, so upgrading it produces a clear bump in volume — especially at full throttle and on cold starts.

Starting at the turbos, they use one solid 4.4\" x 3\" collector welded to an OEM-style 5-bolt flange that bolts up to any 4.0T turbo upgrade. A stainless flex section relieves stress from the turbos under hard acceleration, cornering, and braking, and the OEM transmission mounting brackets are retained to lock everything in place.

The result bolts to the turbos and midpipes with factory-like precision. A mesh flex section relieves stress between the upper and lower halves of each downpipe, and to take strain off the turbos we added two brackets: an upper that secures above the flex joint to the engine block, and a lower that secures below it to the transmission housing — the same anchor points BMW designed for the factory downpipes, for a strong and lasting fit.
