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.

Good Salt Grinder
Size: 5.3 Inches - 1 Pack
Bought this for the pink salt. It crushes it nicely and is easy to fill. The crushing didn't change the taste and this holds a considerable amount of sale. It's a great value for the money and would make a terrific gift.

Works great!
Color: 1 pk
I almost returned this item because, as some others also mentioned, the top is very hard to remove. It needs a little indentation for your finger! But I liked the size and style so I persevered and once you remove it a few times, it eventually comes off easier. This grinder works beautifully. It’s lovely on your table as well as your spice rack. The adjustable grind levels makes it easy to use and I highly recommend this item.

Exactly as I it hoped it to be!
Color: 1 pk
Such a great, little pepper grinder! Works very well and the adjustable grind size is a nice feature. Highly recommend if you need one that doesn't take up too much space.

much better than standard plastic cutting blades
Color: 2pk
They work well, and I'm not getting ground up plastic in my food. One issue--the thin tops can be difficult to pry off, even with fingernails. One of the tops came apart (metal cover, black plastic inner part), so I'll have to glue them together.

Grinds like a champ
Color: 2pk
It was meant to replace an older, different set of grinders, and so far, it's holding up well, and grinding the peppercorns easily. The salt crystals are mostly uniform, but that's OK since we don't use it as a finishing salt. If we ever need to replace them, which I hope not this soon, we'd buy this one again.
