PROFILE


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. 

TRANSFORM THE SOUND OF YOUR B58

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.


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 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.

IN THE BOX

• 1x ARM B58 Single Exit Exhaust

Best choice! Absolutely necessary for anything above basic stock bass.
Bonded to services well, completely removed panel reverberation in my tacoma. Also really made the doors so much quieter even when closing. Very happy with the result. Used only one set on my 01 tacoma 4 door. Installed inside doors on exterior skin panel, over interior door panel access holes (sealing the door to provide backpressure to door speakers (left drains open)), roof panel, and back wall of cab. Achieved about 70% coverage and am very happy. 2 8in SKAR SVR8 at 1oh on walmart power acustic 2500 (only rated to ~800rms at 2oh, forum showed testing at 1oh worked about 1kw) in 6th order with blow through into cab. With cab gain, im over 130db between ~30 and ~50hz. This was a necessary addition!

Looks good so far, will update once installed
Have not installed this yet, so this is only a first impression review. I bought it to use in the wheel well area on my truck, so I’ll update later once I actually get it on and see if it makes a real difference. So far it looks good out of the box and seems straightforward enough. One thing I’d recommend is making sure you have a sound deadening roller for install, because I would not try putting this on without one. Too early for me to say how well it works for road noise since it is not installed yet, but I wanted to post my initial thoughts for now and will update later.

Great product, very impressed
Looks good, adhesive grabs well, forms well to floor pans. Price is great will be ordering more again. It definitely deadened the tin can sound you can get.
