BMW N63 & N63TU Midpipes For 750i, 550i, 650i - ARM MotorsportsThe ARM N63 Midpipes are designed to unleash the true sound of your 4. 4L twin turbo BMW by replacing both sections of the factory N63 midpipes with a straight piped, free flowing exhaust system.

The ARM N63 Midpipes are designed to unleash the true sound of your 4.4L twin-turbo BMW by replacing both sections of the factory N63 midpipes with a straight-piped, free-flowing exhaust system. The OEM N63 midpipes contain two resonators and a center muffler that significantly mute the aggressive tone of the N63 engine. By removing these restrictions, the ARM N63 Midpipes allow the engine’s natural sound to come through.

Below are sound clips of the ARM N63 Midpipes paired with ARM N63 Downpipes, a combination that dramatically transforms the exhaust note of your N63-powered BMW.

If you already have ARM N63 Downpipes and want to increase the sound level even further, the ARM N63 Midpipes are the perfect upgrade. They provide a noticeable increase in both volume and tone compared to running downpipes alone.

For those who prefer to keep the factory downpipes but still want a more exciting exhaust note, the ARM N63 Midpipes deliver a livelier sound without requiring a downpipe upgrade. In either configuration, the OEM axle-back section is retained, allowing you to keep full control of the factory exhaust valves.

  • Replaces both front and rear midpipes
  • Deletes middle resonators and center muffler
  • Full 3" design for improved exhaust flow
  • Retains OEM exhaust valve functionality




As shown in the diagram above, the ARM N63 Midpipes will replace the middle section of the exhaust, between the downpipes and the axle back section. By retaining the OEM axle back section the original function of the OEM exhaust valves are still retained. Giving you the option to drive around in "Comfort" mode with the valves closed, or switch to "Sport" or "Sport +" to unleash all the sounds of your N63!

CONSTRUCTION

The ARM N63 Midpipes are a full 3" system which connects to the OEM axle back section to retain the OEM valve controls and exhaust tips. The ARM N63 Midpipes are compatible with either the OEM N63 slip-fit downpipes or the ARM N63 Downpipes. If you have an original 2-Bolt style (Pre-2012) downpipes, you can convert to the slip-fit style connection by ordering the ARM N63 Downpipes and N63 Midpipes. 

The ARM N63 Midpipes come in two main sections, the front section and the rear section. The front section connects to the downpipes which utilize the slip-fit style connection. To secure the front section even further, it is also held in place by two brackets which mount to the original N63 midpipes mounting points.

The rear section of the ARM N63 Midpipes connect to the front section using a slip-fit connection. The rear section also utilizes the OEM exhaust hangers to fortify their position even further. The rear section then connects to the OEM axle back section of the exhaust using slip-fit connections which allow you to retain the OEM rear mufflers and valves.


IN THE BOX

• 2x ARM N63 Front Sections
• 2x ARM N63 Rear Sections
• 2x Bracket Clamps
• 2x Sleeve Clamps

Didn’t fit but I made it fit.
The part appears decently made in China. The end that terminates below the oil filter would not mount (too tight). I gently sanded the o-ring groove, lubricated and I put the part in freezer. After two hours of sanding the groove I got the part seated. Good thing I was patient today. Pain in the butt.

Trusted reliable brand
Size: 5 Liter, Style: 1 Pack, Configuration: 5W-30
I recently used LIQUI MOLY Molygen New Generation 5W-30 for an oil change and overall I’m very impressed with the quality. The oil feels like a premium product and the difference in engine smoothness was noticeable almost immediately after the change. The engine runs quieter and smoother, especially during cold starts. This oil uses advanced additive technology designed to reduce friction and protect internal engine components, which helps improve efficiency and extend engine life. It also helps prevent deposits and keeps the engine cleaner over time. () Another thing I like is that it maintains stable viscosity even under high temperatures and heavy driving conditions. It provides excellent lubrication and wear protection while also helping improve fuel efficiency. The oil is also compatible with modern engines, including turbocharged applications, this is a high-quality synthetic motor oil that provides excellent protection and performance. If you’re looking for a reliable oil that keeps the engine running smoothly and helps reduce wear, this is definitely a great option and worth the price.

The best thing you can use in a Tahoe! Period!
Size: 5 Liter, Style: 1 Pack, Configuration: 5W-30
This is like liquid gold for your vehicle,it's molecular make up,is far superior to any oil out there,as it gets hot,it's molecules bind to every component inside your engine and attaches itself to the metal and fills in the stress points,all points really,it basically soaks into the metals,and is by far the most long lasting and does not break down like other oils,I get 10k off one oil change and I have 273,000 miles on my 03 Tahoe and this stuff is incredible I don't have any ticks,clicks,knocks, Nothing,not on fire up,cold start,my truck runs about five degrees cooler,I get a couple more miles to the gallon and my motor purrs like new,I could probably go 12-15k between oil changes,but I change it with the filter at 10K a new AC Delco pf46e and a 5-1/4 qt jug of liquid moly 5-30 full synthetic a new crush washer and I'm good for 10,000 miles Easily.
