Putting the mufflers on this bike is exhausting. [laugh track]. Okay, I just couldn’t resist that one.
I decided to replace the exhaust system due to the amount of corrosion I found on the original one. This year/model bike has two cross-over pipes while the earlier year airheads (before the 1981 model year, or before 09/1980) had a single cross-over pipe beneath the front engine cover. The rumor is the second cross-over pipe improves engine performance over the single pipe models. I got the exhaust system from Euro MotoElectrics
I also install the Brown’s side stand that came with the bike as it attaches to the left side header bracket and the front hole of the side stand bracket uses special bolt and nut supplied with the side stand. There is also a toothed washer for the rear hole that mounts on the rear engine stud with the standard nut to keep the side stand bracket from rotating on the engine stud.
Here is a link to the detailed installation procedure and a short video summary of the installation.

I just installed a Brown stand on my 71 R75/5 and it is pretty stout. Does the second crossover pipe interfere with the center stand?
Hi Scott, Well the center stand is the next item on the list to install. Since BMW used this center stand with the rear cross-over pipe exhaust system, I don’t anticipate any clearance problems.
