TRANSFORM THE SOUND OF YOUR B58

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.
