Group Buy: DKF Drone Canceling Exhaust Hanger

Hey guys Im new to the Forum but you all can find me on Zpost. I come here to spread the word about an exhaust hanger that I have been using now for about a year. DKF has been on Zpost making full exhausts for the Z4M Roadster and Coupe. In their process of success they engineered an exhaust hanger that bears the exact same fitment properties as the OEM exhaust hanger found on the E36 chassis. Basically the benefits found in the R&D for the Z4M can be had in the E36. Ive attached all the info if anyone is interested.

DKF has yet to get any pics of these installed on an E36 so this may involve a volunteer for a test fit. One member can try this set out free of charge. Who ever is interested let me know, looking foward to test fitting the first E36M3

yes they are they provide perfect tip alignment If you are doing an aftermarket exhaust or about about to do one theses little hangers here can save you a ton of time. And give you that exact tip placement you are looking for.

This is some information from DKF hope this helped in explaining what the hanger do and how well they are made:


DKF Hangers:
-For anyone who has installed exhaust on our cars and worked hard to get the perfect tip alignment, DKF has created a serious solution for this. The hangers allow left to right and up and down adjustment independent of one another. This is a huge improvement when compared to the spherical joint that BWM uses where all alignment relies on the spherical joint and a two bolt flange.

-The hangers have also been designed to dampen and help eliminate drone by using an isolation pad between the hangers and body, isolation mounts between the mufflers and the hangers and isolation washers

-I have been using the hangers for about 300 miles and really like them. They have allowed me to get perfect exhaust tip alignment with he rear bumper and do help tone down the drone inside the cabin.

-In the realoem.com diagram I added, the green arrows point to the OEM parts the DKF hangers replace

Here are the specifications and description DKF e-mailed to me:
Hanger specifications


1. 3/8 304 S/S lazer cut
2. lazer welded joints
3. vibration isolation washers
4. isolator mounts
5. 1/4 silicone rubber to insulate hanger from bottom of car.

The unique design of the hanger virtually allows you to correct any tip issues you may encounter, by allowing you to align your tips perfectly, in any plane you choose. As many of us know , if you over torque the OEM hangers this can produce cab vibration and drone which as we know can be very unpleasant and hard on the ears ( not to mention nerves). The silicon isolators will virtually eliminate the dreaded cab vibration and drone by allowing the exhaust to stretch in the correct direction eliminating stress on the hangers. The washers provided in the kit are silicone which help delete the transfer of vibration which lead to cab/drone. Lastly we have selected a 1/4 inch silicone isolation pad, to virtually eliminate the transfer of vibration from the hanger to the car. The innovative design of the hangers and the use of the silicon isolators allow us to greatly reduce or eliminate the cab/drone caused by the vibrations transmitted to the car body through the exhaust. The end result is a more enjoyable driving experience.
