PROFILE


The ARM 340i/440i Single Exit Exhaust is the final step in your 340i/440i exhaust modifications. This is for the all-in 340i/440i enthusiast, seeking the lightest and loudest exhaust available.  You will see significant weight savings and an engine note that SCREAMS. 

The ARM 340i/440i Single Exit Exhaust connects to the end of the ARM 340i/440i Midpipe, extending the 3.25" midpipe all the way to a passenger-side single exit tip. The ARM 340i/440i Midpipe upgrade is required to fit the ARM Single Exit Exhaust. This item is for the axle-back section of the exhaust only, for the full exhaust upgrade please select the ARM 340i/440i Midpipe option above. 

TRANSFORM THE SOUND OF YOUR B58

Completely removing the muffler and all resonators, the ARM 340i/440i Single Exit Exhaust allows the most direct flow of exhaust from your B58 out to the single exit 3.25" tip.



CONSTRUCTION

Built from high quality T304 stainless steel and mandrel-bent curves, this ARM B58 Single Exit Exhaust is functional art for your BMW. This section of the exhaust is the final section to complete the ARM 340i/440i Midpipe that starts with the ARM B58 Downpipe. This specific section will connect to the midpipe and secure to the hanger on the passenger side, leaving a single 3.25 tip coming out of the passenger side of the diffuser.

Utilizing a 3.25” piping system you will get the absolute most exhaust flow out of your B58 powered 340i/440i. You will save over 20lbs when you replace your OEM 340i/440i exhaust with the full ARM 340i/440i Single Exit exhaust!



The ARM 340i/440i Single Exit exhaust can be fitted with no cutting or trimming of the OEM System and can be swapped in 45 Minutes with a basic tool set. This leaves it a great option if you want to swap back to a stock muffler in the future.

Shipped quickly and as described
It was what I expected as functionality, lightweight and easy to move about. I plan to use it in my enclosed patio to obscure weight bench and wts. My only complaint is that the bamboo cover on one edge is not secure. But I will probably use a magic marker to cover the natural back that is showing. I don’t have time to return it as my event is coming soon.

Good product, needs double hinges for versatility.
Size: 6 Panel, Color: Brown
Blocks out all the light, looks good, good color. Only con is that it is not double hinged so it is hard to position the extra panels because I bout 6 panels instead of the 4 I usually get. Good deal, very decent price with the free delivery. Very clean packaging, came in great shape, no smell or odor from the factory.

Very Pleased with Room Divider
Size: 4 Panel, Color: Brown
This room divider is even better than I expected. It's sturdy but is lightweight enough that I could get the box up a flight of stairs with no problem whatsoever. It folds and unfolds easily and is very easy to move. And there's no assembly required! It really is woven and is quite attractive. The main reason I chose this item was price (although I did like the way it looked) and I got more for my money than I thought I would.

Works well
Size: 4 Panel, Color: Coal Black
i bought this for 3 reasons. 1. Privacy when changing so I don't have to lock dog out of room. 2. In case MIL comes over and wants to snoop. She won't be able to see my bedroom. 3. A nice backdrop to use when taking photos of the clothing I make. This is perfect for me. My only "complaint" is that it is not the most sturdy thing. I have to finagle it in a way that keeps it from falling over. But for the price, it can't be beat!

Cheap and unstable
Size: 4 Panel, Color: Black, Size: 4 Panel, Color: Black
Although this has nothing to do with the product, it arrived a day later than previously stated. Making me have to create a makeshift room divider the day it was actually needed. When the product arrived it arrived in a box that showed no evidence of damage. Once opened, divider was found inside a plastic cover. Great protector for dust or scratching. The divider was fully assembled so there was nothing for me to do but remove it from packaging and use it where needed. After further inspection the divider was not only cheap and flimsy looking it was absolutely unstable. It would wobble and appears to have been assembled in a rush making some panels crooked. I noted significant damage to the bottom portion of some of the panels both front and back. It does not feel like an item worth the price. The color is as advertised and the product had no smell. The sizing was accurate.
