The N20 has a stock downpipe with a catalyst that drastically restricts exhaust flow. This limits not only the amount of power N20 can make on the stock tune, but also prevents upgrading to a stage 2 tune due to excessive back-pressure. <strong>An N20 downpipe upgrade is the first hardware upgrade every N20 owner should invest in.</strong> Upgrading your downpipe unlocks the most power, increases turbo spool, allows you to run stage 2+ tuning, and improves the exhaust note of your N20 powered BMW. </p> <h1 style="text-align: center;">CONSTRUCTION</h1> <p style="text-align: center;">The ARM N20 Catless Downpipe is built with mandrel bent <strong>SS304 stainless steel</strong> and backed by the <strong>ARM Motorsports</strong> <strong>Lifetime Warranty</strong>. The ARM N20 Downpipe starts with a <strong>4" diameter</strong> at the precision CNC machined turbo v-band connection and gradually reduces to a 2.5" diameter to optimize exhaust flow while matching up to the stock mid-pipe. The ARM N20 Downpipe also features two mounting points to reduce tension on the turbo from shifting and twisting during aggressive driving. </p> <p style="text-align: center;">The ARM N20 Downpipe features two O2 sensor bungs to allow for reinstallation of the OEM oxygen sensors. An<span> tune or CEL Delete will be required to avoid a check engine light from displaying on instrument panel.</span></p> <p style="text-align: center;"> By reducing the back-pressure on your turbocharger, the ARM N20 Downpipe prepares your 320i / 328i for higher boost tunes. Testing on our 328i with only a Stage 1 tune yielded a very respectable 17whp and 25wtq gain. While switching to a Stage 2 tune gave it an additional 13whp and 12wtq, <strong>a total gain of 30whp and 38wtq over Stage 1 alone.</strong></p> <p style="text-align: center;">In addition to helping your N20 make more power and torque, it also opens up the otherwise tame exhaust note. If you're running a stock midpipe and catback section you'll notice a substantial increase in volume under full throttle and a moderate increase in sound during part throttle. Coupled with a midpipe or full exhaust your N20 can sound quite impressive. The ARM N20 Downpipe connects to any aftermarket exhaust that is compatible with the stock N20 downpipe.</p> <p style="text-align: center;">All ARM Motorsports Products are backed by a 30 Day Guarantee and ARM Limited Lifetime Warranty. </p> <h1 style="text-align: center;">IN THE BOX<br> </h1> <div style="text-align: center;"> <span>• ARM N20 Downpipe</span><br><br> </div> <div
