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

It’s a great buy. In process of ordering my third one decided to write a review. I never write reviews . Such a simple product but worth every penny . My dogs favorite toy .

Not recommended at all for heavy chewers
Size: Large (5" x 3.25" x 9"), Size: Large (5" x 3.25" x 9")
They advertise this toy as a heavy chewer toy and it’s not. My big dog chewed through it in a couple days and that’s with me yelling at him to chew it gently. I like the toy and it’s great for smaller less advid chewers. I put kibble in the holes and watch my Shiba go to town throwing it around but my mixed lab/dane has a nub of rubber left. So maybe don’t advertise it as a heavy chewer toy. The rubber is way too soft for you to be suggesting that. It did come with a strong chemical smell that my dogs didn’t like and I had to wash it 3x before they’d touch it.

Great value, durable, enriching
Size: Large (5" x 3.25" x 9")
$5 for the large size for our 15lb chiweenie mix was PERFECT. Her emotional support chew toy got destroyed and I wanted something I felt safe leaving in her kennel while I was out. She anxiously chews. Bought this to try out and she took a bit to get into it, but now she loves it. Probably could’ve gone with a smaller size, but oh well. We put treats inside and smear peanut butter or wet food on the dumbbell like ends for enrichment. So far has held up over 3 weeks.
