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.  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.  An N20 downpipe upgrade is the first hardware upgrade every N20 owner should invest in.  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. 

CONSTRUCTION

The ARM N20 Catless Downpipe is built with mandrel bent SS304 stainless steel and backed by the ARM Motorsports Lifetime Warranty.  The ARM N20 Downpipe starts with a 4" diameter 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.  

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. 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, a total gain of 30whp and 38wtq over Stage 1 alone.

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.

All ARM Motorsports Products are backed by a 30 Day Guarantee and ARM Limited Lifetime Warranty.

Perfect Drawer Organizers—Love the Assorted Sizes
Color: Clear
I really love these drawer organizers. The quality is great, and the assorted sizes are exactly why I decided to purchase them. I used a few inside my vanity to help keep everything more organized, and they work perfectly for separating smaller items without everything getting cluttered together. I like that there are multiple sizes included because it makes it easy to customize the layout for different drawers and products. One feature I really appreciate is the non-slip bottom. They stay in place well and don’t slide around every time I open and close my drawers, which makes a huge difference. The clear plastic design also makes it easy to quickly see where everything is without digging through the drawer making a mess. They feel sturdy and durable, not flimsy like some other organizers I’ve tried. I also like that they can be stacked when not in use, which helps save space. Best for: vanities, makeup organization, bathroom drawers, office supplies, and general home organization Overall, these are practical, well made, and really help make drawers look cleaner and more organized. Definitely happy with my purchase.

Clear, Stable, and Surprisingly Better Than IKEA
Color: Clear
I didn’t expect to be this impressed by drawer organizers, but the Vtopmart 25 PCS Clear Plastic Drawer Organizers really delivered. The non-slip silicone pads actually work — once placed, the trays don’t slide around at all, even when opening and closing drawers frequently. That alone makes a huge difference in daily use. What I love most is how much space they save while keeping everything clearly visible. The clear plastic makes it easy to find what I need at a glance, and the variety of sizes lets me customize each drawer instead of forcing everything into awkward layouts. All the organizers have a solid, usable depth, so items don’t tip over or feel cramped. Cleaning is effortless — a quick wipe and they look new again. Compared to IKEA organizers I’ve used before, these feel more practical, easier to maintain, and honestly more flexible. Add in the great price for a 25-piece set, and this feels like one of those simple purchases that quietly makes everyday life more organized and less frustrating.

nice set
Color: Clear Black
I bought this set to organize a messy desk drawer and it made a huge difference right away. Having multiple sizes in one pack is what really makes this set useful. I was able to customize the layout instead of trying to force everything into a few fixed compartments. The trays feel sturdy enough for everyday use and the clear design makes it easy to see everything at a glance. I used them for things like pens, paper clips, chargers, and random small items that usually get lost, and now everything actually has a place. They also don’t slide around much once placed, especially if the drawer is fairly full, which I appreciated. Setup took just a few minutes and instantly made the space look cleaner and more put together. If I had to note anything, the plastic is lightweight, so it is not heavy duty, but for organizing office supplies it works perfectly fine. Overall, a really practical set that helps you stay organized without overthinking it.

Great organizers!
Color: Clear
This is a really practical organizer set. I used it in my bathroom and nightstand drawers, and it helped clean everything up fast. The different sizes are the best part—you can mix and match depending on what you’re storing. Only reason I’m giving 4 stars is because the plastic isn’t super heavy-duty, but it’s still perfectly fine for everyday use. Good value for the amount you get.
