The ARM M240i Single Exit Exhaust is the final step in your M240i exhaust modifications. This is for the all-in M240i enthusiast, seeking the lightest and loudest exhaust available.  You will see significant weight savings and an engine note that SCREAMS. 

The ARM M240i Single Exit Exhaust connects to the end of the ARM M240i Midpipe, extending the 3.25" midpipe all the way to a passenger-side single exit tip. The ARM M240i 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 M240i Midpipe option above. 


Completely removing the muffler and all resonators, the ARM M240i Single Exit Exhaust allows the most direct flow of exhaust from your B58 out to the single exit 3.25" tip.


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 M240i 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 M240i. You will save over 20lbs when you replace your OEM M240i exhaust with the full ARM M240i Single Exit exhaust!

The ARM M240i 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.
